Want to buy a new Mac and don’t want to spend a fortune? Buying a new Mac is an expensive business, but there is a way to get a new Mac for less money.

We don’t mean buy a second-hand Mac from someone on eBay. We mean you can get a brand-new Mac directly from Apple for less money. Read Should I buy a secondhand Mac?

Want to know how? Shop at Apple’s Certified Refurbished Store. On the Refurbished Store you can find Macs from the past few years all with money off Apple’s usual price. See just how much you can save here: How much can you save at Apple’s Refurbished Store.

The price isn’t the only reason to shop at Apple’s Certified Refurbished Store though. Here we’ll tell you all the reasons why you should buy a refurbished Mac.

Apple’s not the only place that sells refurbished Macs. We discuss the Best place to buy a refurbished MacBook or Mac in a separate article and also make some recommendations below.

1. Refurbished Macs are as good as new

You might be thinking that buying from Apple’s Refurbished Store is a bit like buying secondhand, assuming that the Mac had a previous owner and for one reason or another they returned their Mac to Apple. Your concern might be that this means there is something wrong with the Mac, but as you will see from the point below, Apple will have identified and fixed any faults.

The Mac you are buying probably hasn’t come straight from the factory, but its interlude with a prior customer will have been brief. The previous owner may have exercised their consumer rights and returned it unused within 14 days (which is the extent of Apple’s refund and exchange policy). Or the Mac might have been used as a demonstration model, but this doesn’t mean that it will have been used by lots of people and it is unlikely to have undergone any intensive processing.

2. You can get the current generation Macs for less

You can save money on the current generation of Macs if you shop in the Refurbished Store.

For example, in July 2023 we found a refurbished 13-inch MacBook Air with M2 chip for $929, which is a saving of $170, and less than the M1 MacBook Air still sells for.

It usually takes a few months before Apple starts selling the current generation of Macs on the Refurbished Store, but Apple started selling refurbished M2 Pro and M2 Max MacBook Pro and M2 Mac mini in the refurbished store in May 2023, about four months after they initially went on sale in January 2023.

3. You can get more for your money

Buying from the Refurbished Store is a great way to get a more powerful Mac than the current entry-level for less money.

If you shop for your Mac in your local Apple Store, at an Apple Authorized Reseller, or in Apple’s online store, you can only buy the newest version of a particular Mac. Turn instead to the Refurbished Store and you will find Macs from the past few years at a lower price than their successors.

The really enticing thing is that these older Macs often aren’t a lot different from the current models. Sure, the newer Mac might have the next-generation processor, but if you had the choice of an M2 or an M1 Pro then the M1 Pro would still be a more powerful option. See our Mac processor comparison.

For example, we took a look at the Apple Refurbished Store in July 2023 and found a refurbished 14-inch MacBook Pro with M1 Pro chip (14-core GPU, 512GB SSD, and 16GB Unified Memory) for $1,539. This is a saving of $360 on the $1,899 price it had when it was new. But the deal is even better when you consider that a brand new 13-inch MacBook Pro with M2 chip, configured to have the same 512GB SSD and 16GB memory, would cost $1,699 and would be a less powerful Mac with a 10-core GPU.

Typically you can see the following savings at Apple’s Refurbished Store for the current generation and older generation Macs:

• $90-$170 off a MacBook Air.
• $190 -$610 off a MacBook Pro.
• $90-$200 off a Mac mini.
• $200-$260 off an iMac.
• $270 off a Mac Studio.

There are also some big savings to be had on Intel-powered iMacs.

4. Apple tests and replaces parts if necessary

You might be thinking that this is all very well, but these are Macs that are likely to have been returned to Apple due to a fault with them. Would it be unwise to buy a Mac that has already proven to be faulty?

The great news here is that you can be sure that any fault will have been rectified by Apple. The company says that all refurbished Macs include “full functional testing, genuine Apple part replacements (if necessary),” as well as “a thorough cleaning”.

The Mac you are buying will have had more checks than any Mac coming straight from a factory so you can be sure that any problems will have been caught.

5. You get a one-year warranty and 90 days of tech support

Even better, you get a one-year warranty, so if anything does go wrong getting it fixed will be easy and free.

You also get complimentary technical support, which means you will be able to phone Apple up if you have any problems with setup, installation of software, and any connection problems.

You can also extend the one-year warranty up to three years if you buy AppleCare protection when you purchase your refurbished Mac.

If you buy secondhand from another source you will only have any remaining warranty left over–and since the model you are buying is likely to be more than a year old this protection will have expired.

6. It’s dispatched for free with free returns

Because you are buying the Mac from Apple directly it comes with other benefits. For example, not only will there be no shipping costs associated with your new Mac (Apple will dispatch it to you for free).

You will also be protected by Apple’s 14-day returns policy, which means that if you change your mind you can send it back, no questions asked, within two weeks.

7. You could get your new Mac today!

Another benefit is that if the Mac is in stock at your local Apple Store you could pick it up today. And if you would prefer that it was delivered to you, it could arrive as soon as tomorrow.

8. You can purchase your refurbished Mac with financing options

If you don’t have the money right now you can still get your new Mac. Apple offers financing options. In the U.S. Apple offers its own Apple Card which brings the advantage of 3% Daily Cash Back when you buy from Apple.

The Apple Card isn’t available in the U.K., but Barclays and PayPal Credit provides finance if you want to buy a new Mac. You just need to apply for financing when you check out.

You can also trade in an old product to get credit toward your new purchase. You could get up to $775/£615 credit for trading in a MacBook Pro, for example.

9. You don’t have to deal with a previous user

Dealing with Apple is a real benefit. You don’t need to deal with a previous owner who might not be completely honest about problems with the machine, or might be difficult if later on you experience problems.

Dealing with Apple directly should give you peace of mind that you are buying exactly what is advertised and that if there are any issues they will be dealt with professionally.

10. You might be able to save even more

Apple isn’t the only place you can buy a refurbished Mac. There are a number of Apple Resellers and Refurbishment specialists who will also sell you a secondhand Mac that has been thoroughly checked over.

We’d advise that you are a little more cautious if it isn’t Apple selling the refurbished Mac, and we recommend that you don’t buy a very old Mac, even if it has been refurbished, but this can be a good way to get a reasonably new Mac for less.

These refurbished stores will have thoroughly checked the Mac so you can be confident it will work!

Do Macs get viruses? Do Macs need antivirus software? The answers to these questions aren’t as simple as they might seem. In this article, we look at the dangers faced by Mac users, and the pros and cons of using Mac antivirus software.

Historically, the Mac has been considered safe and secure for a number of reasons that we will go into below, but in recent years the consensus has fluctuated. In its 2020 State of Malware report, Malwarebytes said it saw “a significant rise in the overall prevalence of Mac threats in 2019, with an increase of over 400 percent from 2018.” The following year, the company found that overall malware detected on macOS decreased by 38 percent but that the worst kind, namely “backdoors, data stealers, and cryptocurrency stealers/miners,” increased by more than 61 percent.

One reason for the decline in 2020 was the pandemic; as restrictions were lifted, malware saw a resurgence in 2021, with the number of Mac detections soaring by more than 200 percent to an astonishing 164 million. Even Apple software boss Craig Federighi acknowledged in May 2021 that Mac malware was a problem… although it’s worth bearing in mind that at the time he was trying to make the case for iOS’s very different approach to security. “Today,” he said, “we have a level of malware on the Mac that we don’t find acceptable.” Federighi revealed that 130 different cases had been documented since May 2020, and that one of these had affected more than 300,000 Macs. He even admitted that members of his family had got malware on their Macs.

When the judge asked about the fact that Mac users can purchase and download software from various places on the Mac, rather than being limited to the Mac App Store, Federighi said: “Yeah, it’s certainly how we’ve done it on the Mac and it’s regularly exploited on the Mac. iOS has established a dramatically higher bar for customer protection. The Mac is not meeting that bar today.”

Federighi noted that Mac users don’t download as much software as iOS users, and argued that if iOS was as open to third-party downloads there would be a real problem for that platform. “If you took Mac security techniques and applied them to the iOS ecosystem, with all those devices, all that value,” he said, “it would get run over to a degree dramatically worse than is already happening on the Mac.”

To get a feel for the number of attacks on the Mac platform, browse our complete list of Mac viruses, malware and trojans. Adware and Potentially Unwanted Programs (PUPs) make up the majority of the malware detections on Macs, according to Malwarebytes.

Do I need antivirus for Mac?

So should Mac users start panicking? No. Mac malware does pose a risk that users should be aware of, but it doesn’t follow that Macs absolutely must be equipped with antivirus software. Such products have their advantages and you may choose to install one for more peace of mind, but we don’t view them as essential for the Mac.

For one thing, there are measures put in place by Apple at the operating system level that should protect Mac users from the worst malware threats. These built-in security features make attacking a Mac particularly challenging. They include Gatekeeper, which blocks software that hasn’t been digitally approved by Apple from running on your Mac without your agreement, and XProtect, which is Apple’s own antivirus built into macOS and inspects every app for malware.

As you can see, Apple goes to great lengths to protect you from malware by making it almost impossible for you to download it in the first place, let alone install it. Additionally, Apple does a pretty good job of keeping on top of vulnerabilities and exploits; if your Mac needs to be protected from these, a patch will quickly be pushed out over auto-update.

Thanks to these features, before you can install an app, your Mac will check it against a list of malware, and even if there is no reason for concern it will not make it easy for you to open an application from a developer that hasn’t been approved.

These features and other protections built into macOS (which we will discuss in more detail below) mean it’s not an essential requirement to install antivirus software on your Mac.

However, as good as these protections are, there have been occasions when malware has managed to infiltrate the Mac platform, and times when Apple hasn’t responded to a threat as quickly as Mac users might hope. If you want the very best protection from threats, therefore, consider adding a dedicated Mac security suite such as Intego Mac Internet Security. You’ll find Intego at the top of our roundup of the best antivirus for Mac, among other free and paid-for antivirus apps that might give you some peace of mind, including McAfee and Norton.

Read on to find out more about how Apple’s security measures work–and why they may not be enough to keep your Mac secure.

How Apple protects Macs from viruses

Macs are generally safer than PCs, but with threats to the Mac growing due to the platform’s increasing popularity, Apple has had to build in protections to macOS and the Mac hardware itself. 

In this section we will look at the built-in protections in macOS to establish whether they are enough, or if you should also install antivirus software on your Mac.

How XProtect works

The Mac’s malware scanning tool, XProtect, works invisibly and automatically in the background and requires no user configuration. Apple has a list of malicious applications that it checks against when you open downloaded applications. XProtect is regularly updated by Apple, and it updates in the background, so you should always be protected.

This is similar to having antivirus software from a third-party software developer running on your Mac, with the bonus of being written into the operating system and therefore not hampering performance.

If you download and try to open files contaminated with malware, you may see an explicit warning that the files will “damage your computer,” along with a reference to the type of malware. In that case you should delete the file immediately.

This is great news for Mac users, but is it enough? How does XProtect compare to the antivirus solutions out there? Well, XProtect may not be as up to date as some third-party products and it doesn’t look for as many strains of malware. Read our roundup of the Best Mac antivirus apps for an in-depth evaluation of the options out there.

How Gatekeeper works

Thanks to Gatekeeper, macOS blocks downloaded software that hasn’t been digitally signed, a process whereby Apple approves the developer. This leads to the familiar error message when you try to use or install unsigned software: “[This app] can’t be opened because it is from an unidentified developer.” One change to Gatekeeper that arrived in macOS Catalina a few years back was that software is checked for malware and other issues every time it runs, rather than just the first time you install it.

For maximum protection, GateKeeper can be set to only allow software to be installed if it was downloaded from the Mac App Store. Or you can set it to allow you to install software from the web, but from verified developers only.

You can adjust these settings via the Security & Privacy section of System Preferences:

1. In Security & Privacy, select the General tab. 
2. Choose from the options underneath Allow Applications Downloaded From.
3. Choose App Store or App Store and Identified Developers.

The safest option is App Store only, but if you also want to be able to install legitimate software from the web then App Store and Identified Developers is the best plan. There used to be a further option to disable the feature by choosing ‘Anywhere,’ but this option is no longer available.

All software downloaded via the App Store is signed, but should you attempt to open an app you’ve downloaded from the web that isn’t signed, you’ll see a Gatekeeper warning like the one below:

This may mean you’ve almost installed malware. On the other hand, of course, it may be a legitimate app. In which case (and if you’re sure) you can bypass Gatekeeper’s protection and install it.

To do so, go to the Finder and locate the app there. Now hold down Ctrl when you click on the app, and then select Open. This will mark it as being trusted. For more details, read how to open an app from an unidentified developer.

Being able to download unsigned software might sound like a benefit, but it essentially enables you to bypass the protections offered by Gatekeeper. That’s a mixed blessing, and more and more malicious apps are instructing users to do exactly this when they are installed.

Sandboxing and related protections

Software that is approved by Apple is also sandboxed, which means apps do only what they’re intended to do. App sandboxing isolates apps from the critical system components of your Mac, your data and your other apps, so they shouldn’t be able to do any damage. It doesn’t protect you from malware getting into the system, but it does limit the extent of what the malware can do once it’s in there.

The main problem here is that while apps sold on the Mac App Store have to be sandboxed, other Mac apps don’t.

However, even without app sandboxing, there are related features built into macOS that should still stop apps snooping on your data. Since macOS 10.15 Catalina in 2019 it has been a requirement for all Mac apps to get your permission before they can access your files. macOS will also ask for your permission before an app can access the camera or microphone, or log what you type.

Another change that arrived with Catalina is that macOS itself is now stored on a separate disk volume. This means that your important system files are all completely separate and therefore more challenging to access. Apps can’t get to your system files where they could cause problems.

Security updates

Apple regularly issues security updates for the Mac. While these can serve to demonstrate that the Mac isn’t infallible, with Apple all too frequently having security flaws pointed out to it, they are generally issued promptly.

Less pleasingly, these security updates have generally been issued as part of a larger macOS update: for example, macOS Monterey 12.2.1 closed a security vulnerability in WebKit that would have made it possible to execute malicious code. Because these security fixes were issued as part of a macOS update, which often requires the computer to reboot during the install process, Mac users may be less likely to install the update promptly, even though these updates can be set to install automatically.

Since the launch of Ventura, however, Apple has started separating out the security updates from wider macOS updates and rolling them out automatically. This way the update can happen in the background, without a restart.

Password protection and Passkeys

Apple improved the way users can manage passwords in macOS Monterey and also made some changes to two-factor authentication. You can find all your Passwords in System Preferences > Passwords. You just need to unlock it with your main password to see every other password you have. (You can also view this information on your iPhone in Settings > Passwords.)

In Monterey a new authenticator was added, so you can set up verification codes instead of using an authentication app. To add a setup key you need to click on a password and then choose Enter Setup Key, which you should be able to obtain from the provider. Once input the 2FA verification codes should automatically fill.

In macOS Ventura Apple moved from passwords to passkeys. Apple explains: “Passkeys use iCloud Keychain public key credentials, eliminating the need for passwords. Instead, they rely on biometric identification such as Touch ID and Face ID in iOS, or a specific confirmation in macOS for generating and authenticating accounts.” Passkeys are more secure, according to Apple. Essentially your device will hold one part of a cryptographic key pair and the other part will be stored by the website or service you’re logging into. Your device will authenticate you biometrically (with Touch ID or Face ID) and log you in. For more information, read How to use Passkeys.

Recording alerts

In macOS Monterey Apple added a Recording indicator in the menu bar so you’ll know if an app is recording you. A bit like the light that indicates the mic is in use on your iPhone.

Pasteboard alerts

Similarly, as of macOS Ventura, any app that wants access to your pasteboard has to request permission.

Safari protections

Anti-phishing technology in Safari will detect fraudulent websites. It will disable the page and display an alert if you visit a suspect website.

Anti-phishing isn’t the only way that Safari protects you when you’re surfing. Apple also allows users to prevent advertisers tracking them around the web. You can see a Privacy Report including details of all the cross-site trackers Apple has stopped from profiling you.

You’ll also notice that plug-ins such as Silverlight, QuickTime, and Oracle Java won’t run if they aren’t updated to the latest version, another way of ensuring your Mac is safe. And of course now that Adobe has discontinued Flash people should hopefully no longer fall for malware hidden in Flash Player.

Safari will also flag up weak passwords and make strong password suggestions when you open an account on a website. This strong password will be saved in your iCloud Keychain so you won’t have to remember it. It’s a lot safer than using the same password you always use. For more on this subject, read about How Apple plans to retire passwords.

In the past, one issue with Apple’s suggested passwords has been that sometimes they don’t match the website’s requirement. For example, a website may require one upper-case letter, one special character, one number and so on. As of the launch of Ventura, macOS allows users to edit suggested passwords so they meet these requirements.

New in Safari 15 were improvements to the Intelligent Tracing Prevention that arrived in Safari 14. Now web trackers won’t be able to see your IP address so they won’t be able to create a profile about you. Check this by choosing Safari from the Safari menu > Preferences > Privacy > Hide IP address from trackers.

Photo privacy

A few years ago there was a lot of bad publicity for Apple when celebrities reported that their iCloud photos had been stolen. (For more on this, read How to stop photo hacks on iPhone.) There have been a number of security enhancements in iCloud since this happened, and Apple has given users other ways to protect their photo privacy: for example, the ability to hide photos and albums. In Ventura, Apple expanded this so that hidden albums, and the Recently Deleted album, are locked by default, and only authenticated by Touch ID or Face ID.

Mail protections

macOS Monterey brought a new feature in Mail on the Mac. Mail Privacy Protection improves privacy for users. For example, it stops email senders from being able to track whether you’ve opened an email, or even determine your location from your IP address. Check that the feature is working for you by opening Mail > Click on Mail in the menu > choose Preferences > Privacy > and make sure Protect Mail Activity is selected. It should be by default.

There are additional Mail protections if you’re an iCloud subscriber. Hide My Email allows you to create an alternative email address that you can give out. The email will still be delivered to your inbox, but you can easily delete the alternative email later.

You can turn this on in System Preferences > click on Apple ID > and select Private Relay (currently in Beta). 

In Ventura Hide My Email was extended to third-party apps.

iCloud+ protections

If you’re an iCloud subscriber, you’ll be interested in a feature that arrived in Monterey (part of the upgrade from iCloud to iCloud+) called Private Relay. It’s a bit like a VPN in that it encrypts your network traffic and routes your DNS lookup requests through two servers, one of which is not controlled by Apple. However, it’s not a VPN, because it only works in Safari and obviously it lacks the other usual features of a VPN. (If you want a VPN, by the way, check out our roundup of the best VPNs for Mac. You may even be able to save some money if you take a look at our roundup of VPN deals, or try one of these free VPNs.)

You can manage your Private Relay settings in System Preferences > Apple ID > click on Options beside Hide my email. Here you will see any fake email addresses you’re using; just click on Turn Off if you want to stop those emails arriving. You can also change which email address they are forwarded to. 

Safety Check

A new feature in macOS Ventura is Safety Check, a feature that will allow anyone who is concerned that they are in danger from a person known to them to revoke any access they have granted to that person. So, for example, that person won’t be able to access their location, their photos, or anything else that could help them to be traced.

File encryption with FileVault

In addition to Gatekeeper, which should keep malware off your Mac, FileVault 2 makes sure your data is safe and secure by encrypting it.

If you’re concerned about someone being able to access the files on your Mac you can encrypt them using FileVault, which will mean only you can unencrypt them. Read our tips for keeping your mac secure, of which using FileVault is one.

Warnings about spyware

Apple announced in November 2021 that it would warn its users of state-sponsored espionage attacks, such as the well-publicised Pegasus spyware, on their iPhones, iPads and Macs. The notification will come via email or a message. The same warning will be displayed on the user’s Apple ID page at appleid.apple.com.

The warning will offer advice about how affected users can protect themselves against attack. There’s more information on Apple’s site.

Find My

Not every threat to your data comes from malware. Sometimes a criminal might get hold of your Mac, in which case Apple’s Find My service will come into its own.

The Find My app can relay the location of your lost or stolen Mac back to you. If you’re concerned that it might not be recoverable, you can wipe the contents of the Mac so that your data can’t be accessed. For more on this, read How to find a lost or stolen iPhone.

In addition, every Mac with an M1-series, M2-series, or T2 chip has an Activation Lock feature that means they can be bricked remotely.

When Apple’s security measures aren’t enough…

All the above is great, but unfortunately there have been cases where Gatekeeper has been bypassed because malware has got an approved developer signature. For example OSX/CrescentCore was able to bypass Gatekeeper because it was signed by a certificate assigned by Apple to a developer. It took Apple a few days to retract that certificate.

It isn’t only when malware gets a certificate from a registered developer. In the case of OSX/Linker, a zero-day vulnerability in Gatekeeper was being exploited.

Zero-day threats mean there are “zero days” to fix the vulnerabilities, although often a legitimate developer discovers the vulnerability and lets the developer know about it. There is usually a 90-day deadline for the fix to be made available. Some times the developer doesn’t act in time and the exploit is publicised.

Apple normally reacts quickly, although there have been cases where the company has ignored the identified vulnerability, such as when a teenager reported the Group FaceTime vulnerability that meant someone could listen in to a call and Apple failed to act. There’s more about how Apple reacts to security threats next.

When Apple is made aware of a threat the company usually issues a security update to the latest version of macOS and to the two versions prior to it. This way Apple will protect users from vulnerabilities and flaws in macOS that could be utilised by hackers.

Normally the advice would be to install the update immediately. However, for example a Sierra and High Sierra security update in July 2019 was subsequently pulled after people experiences problems after installing it.

How Apple responds to security threats

Despite the security measures Apple has in place, from time-to-time there are threats to the Mac.

Apple has its own security research team, but it depends on users and independent researchers to help by reporting any flaws they find in Apple products.

To this end, Apple has an incentive program that rewards such discoveries with payments of up to $200,000, depending on the seriousness of the flaw. But it was the last major tech company to set up such a scheme. (Microsoft set up its own bug-reporting incentive programme in 2013, and was itself criticised at the time for leaving it so late.)

On 4 August 2016, Apple security boss Ivan Krstic announced the Apple Security Bounty Program. “We’ve had great help from researchers in improving iOS security all along,” Krstic said. “[But] we’ve heard pretty consistently… that it’s getting increasingly difficult to find some of those most critical types of security vulnerabilities. So the Apple Security Bounty Program is going to reward researchers who actually share critical vulnerabilities with Apple.”

The top reward of $200,000 is given to those who discover vulnerabilities in Apple’s secure boot firmware components; for less critical flaws the bounties drop through a series of smaller figures to a bottom tier of $25,000. Wired has the details.

We imagine most Mac users will be pleased to hear that Apple has an incentive programme to encourage more widespread reporting of its vulnerabilities. Incentivising security researchers to let Apple know about a flaw instead of passing it on to hackers (which may still, sadly, be more lucrative) makes Apple products safer for everyone.

One such flaw was the High Sierra root bug, discovered on 28 November 2017. This flaw in macOS 10.13 could allow access to settings on a Mac without the need for a password. Apple immediately issued a statement confirming that it was working on a fix and an update was anticipated to be issued within days.

How to keep your Mac safe from malware

Apple does a lot to keep your Mac safe, but you have to work with it, installing updates when they arrive, not clicking on suspicious links in emails, not installing Flash, and so on. There are also some third party antivirus apps you could try – we have a complete guide to the best antivirus for Mac here.

Here are a few of the things you should do:

1) Keep macOS up to date

Despite what we said above about the security update Apple later retracted, normally the advice would be to install a security update as soon as possible.

Apple addresses flaws and vulnerabilities with the Mac by issuing updates to the Mac operating system, it is important to keep your Mac up to date. We advise checking regularly for OS updates remains a key part of a sound security strategy.

You can find out about the latest version of macOS here: macOS Ventura latest version information.

You can set your Mac to automatically update as soon as a new version of the operating system is made available. Follow these instructions to set that up:

How to automatically install macOS updates

1. Open System Preferences.
2. Click on Software Update.
3. Tick the box beside Automatically keep my Mac up to date.
4. Or, click on Advanced and choose from automatically: Check for updates, download new updates when available, Install macOS updates and Install app updates from the App Store.

How to automatically install High Sierra or older software updates

1. Open System Preferences.
2. Click on App Store.
3. Tick the box beside Automatically check for updates.
4. You can choose to download the newly available updates, if you want them to install automatically though you need to make sure the box beside Install macOS updates is checked.

How to manually install macOS software updates

If you’d rather not let your Mac automatically update, you should periodically check to see if there is an update to your version.

• In macOS High Sierra and earlier you can go to the Mac App Store and check for updates.
• In macOS Mojave and newer you need to go to the Software Update pane in System Preferences.

You may need to restart your computer once the update has downloaded. You can expect a typical 460MB download to take about 8 minutes (during which time you will still be able to work) but for a large update you will have to restart and install and that could take as much as 20 minutes, bringing the total install time to about 25 minutes in total.

For our in-depth guide to updating Mac operating systems, see How to update macOS.

2) Don’t connect to public Wi-Fi networks

Beware of connecting to a public Wi-Fi network as there may be someone spying who could gain access to your passwords and other private information, or you could have your session hijacked. Snoopers can set up their own Wi-Fi hotspot, pretending to be your hotel or coffee shop, then once you have connected they can grab any data you send over it. In the past there have been flaws detected in the OS that could allow access to your Mac, such as the SSL error in an earlier version of Mac OS X that meant it was possible for a hacker to access your machine if you were using public WiFi.

3) Don’t install Flash

Adobe discontinued Flash on 31 December 2020 with good reason. Intego, Malwarebytes and others recommended that you shouldn’t install Flash Player. Fake Flash Player updates have often been the means by which people install malware. For example, people want to watch or download a popular movie or TV series for free and they find a search result that leads to a request to update Flash Player in order to view the content. There is no need to install Flash Player now that HTML5 has made Flash obsolete. Now that Flash is no longer be supported the advice is simple: Don’t use Flash!

4) Keep Java up to date on your Mac

If you must use Java (which is also problematic) then make sure it’s up to date. Vulnerabilities with Java have highlighted the fact that there are cross-platform threats that even Mac users need to be aware of. Apple blocks Java by default, leaving it to the user to decide whether to install those tools. If you do need to update them be very careful where you download updates from!

5) Avoid falling foul of phishing emails

Protect yourself from phishing attacks not responding to emails that require you to enter a password or install anything. You could also use free software such as BlockBlock. That way even you were to carry out the steps to launch the malware, it would not be able to write files or mark itself as launching on startup.

6) Don’t fall for Facebook scams

Facebook scams are usually designed to harvest data about the most gullible people, so if it seems like it might be too good to be true it probably is and you’d be wise not to share it on Facebook. At best you might just look silly and those scammers will start to target you with more scams, at worse scammers can access your personal data and that of those you share their post with. So don’t click on a link just because a friend shared it and definitely don’t give out your personal data on Facebook.

Why you need to protect Windows users

One of the reasons why, regardless of how safe a Mac is from malware, we should run an antivirus is to protect our Windows using friends and colleagues. While it’s unlikely that your Mac will run any malware, there is possibly a more pernicious issue: You Mac could become the Typhoid Mary of Windows viruses, which is to say, you could be harboring viruses on your Mac that won’t effect you, but can be problems for Windows users.

Some years ago when writing about Mac malware we identified the following nasties on our Mac:

That is a list of 30 potentially bad things that… you guessed it, were found on the Mac we ran a test virus scan on, one of which was a Windows virus.

How to tell if a Mac has a virus

Look out for the following signs that your Mac has been infected with malware: 

1. Aggressive web page banners and browser pop-ups recommending software.
2. Web page text turning into hyperlinks.
3. Programs appearing that you haven’t authorized.
4. Mac crashes.
5. Mac runs hot.
6. Mac speeds up for no reason.

If you think something suspicious is happening, open Activity Monitor and click on the CPU tab. Check what software is running – especially if something is hogging a lot of your resources.

We discuss how to tell if your Mac has a virus and how to remove a Mac virus in a separate article: How to remove a virus from a Mac and How to protect your Mac against attack and disaster to avoid getting infected.

Antivirus, Personal Software, Security

Do Macs get viruses? Do Macs need antivirus software? The answers to these questions aren’t as simple as they might seem. In this article, we look at the dangers faced by Mac users, and the pros and cons of using Mac antivirus software.

Historically, the Mac has been considered safe and secure for a number of reasons that we will go into below, but in recent years the consensus has fluctuated. In its 2020 State of Malware report, Malwarebytes said it saw “a significant rise in the overall prevalence of Mac threats in 2019, with an increase of over 400 percent from 2018.” The following year, the company found that overall malware detected on macOS decreased by 38 percent but that the worst kind, namely “backdoors, data stealers, and cryptocurrency stealers/miners,” increased by more than 61 percent.

One reason for the decline in 2020 was the pandemic; as restrictions were lifted, malware saw a resurgence in 2021, with the number of Mac detections soaring by more than 200 percent to an astonishing 164 million. Even Apple software boss Craig Federighi acknowledged in May 2021 that Mac malware was a problem… although it’s worth bearing in mind that at the time he was trying to make the case for iOS’s very different approach to security. “Today,” he said, “we have a level of malware on the Mac that we don’t find acceptable.” Federighi revealed that 130 different cases had been documented since May 2020, and that one of these had affected more than 300,000 Macs. He even admitted that members of his family had got malware on their Macs.

When the judge asked about the fact that Mac users can purchase and download software from various places on the Mac, rather than being limited to the Mac App Store, Federighi said: “Yeah, it’s certainly how we’ve done it on the Mac and it’s regularly exploited on the Mac. iOS has established a dramatically higher bar for customer protection. The Mac is not meeting that bar today.”

Federighi noted that Mac users don’t download as much software as iOS users, and argued that if iOS was as open to third-party downloads there would be a real problem for that platform. “If you took Mac security techniques and applied them to the iOS ecosystem, with all those devices, all that value,” he said, “it would get run over to a degree dramatically worse than is already happening on the Mac.”

To get a feel for the number of attacks on the Mac platform, browse our complete list of Mac viruses, malware and trojans. Adware and Potentially Unwanted Programs (PUPs) make up the majority of the malware detections on Macs, according to Malwarebytes.

Do I need antivirus for Mac?

So should Mac users start panicking? No. Mac malware does pose a risk that users should be aware of, but it doesn’t follow that Macs absolutely must be equipped with antivirus software. Such products have their advantages and you may choose to install one for more peace of mind, but we don’t view them as essential for the Mac.

For one thing, there are measures put in place by Apple at the operating system level that should protect Mac users from the worst malware threats. These built-in security features make attacking a Mac particularly challenging. They include Gatekeeper, which blocks software that hasn’t been digitally approved by Apple from running on your Mac without your agreement, and XProtect, which is Apple’s own antivirus built into macOS and inspects every app for malware.

As you can see, Apple goes to great lengths to protect you from malware by making it almost impossible for you to download it in the first place, let alone install it. Additionally, Apple does a pretty good job of keeping on top of vulnerabilities and exploits; if your Mac needs to be protected from these, a patch will quickly be pushed out over auto-update.

Thanks to these features, before you can install an app, your Mac will check it against a list of malware, and even if there is no reason for concern it will not make it easy for you to open an application from a developer that hasn’t been approved.

These features and other protections built into macOS (which we will discuss in more detail below) mean it’s not an essential requirement to install antivirus software on your Mac.

However, as good as these protections are, there have been occasions when malware has managed to infiltrate the Mac platform, and times when Apple hasn’t responded to a threat as quickly as Mac users might hope. If you want the very best protection from threats, therefore, consider adding a dedicated Mac security suite such as Intego Mac Internet Security. You’ll find Intego at the top of our roundup of the best antivirus for Mac, among other free and paid-for antivirus apps that might give you some peace of mind, including McAfee and Norton.

Read on to find out more about how Apple’s security measures work–and why they may not be enough to keep your Mac secure.

How Apple protects Macs from viruses

Macs are generally safer than PCs, but with threats to the Mac growing due to the platform’s increasing popularity, Apple has had to build in protections to macOS and the Mac hardware itself. 

In this section we will look at the built-in protections in macOS to establish whether they are enough, or if you should also install antivirus software on your Mac.

How XProtect works

The Mac’s malware scanning tool, XProtect, works invisibly and automatically in the background and requires no user configuration. Apple has a list of malicious applications that it checks against when you open downloaded applications. XProtect is regularly updated by Apple, and it updates in the background, so you should always be protected.

This is similar to having antivirus software from a third-party software developer running on your Mac, with the bonus of being written into the operating system and therefore not hampering performance.

If you download and try to open files contaminated with malware, you may see an explicit warning that the files will “damage your computer,” along with a reference to the type of malware. In that case you should delete the file immediately.

This is great news for Mac users, but is it enough? How does XProtect compare to the antivirus solutions out there? Well, XProtect may not be as up to date as some third-party products and it doesn’t look for as many strains of malware. Read our roundup of the Best Mac antivirus apps for an in-depth evaluation of the options out there.

How Gatekeeper works

Thanks to Gatekeeper, macOS blocks downloaded software that hasn’t been digitally signed, a process whereby Apple approves the developer. This leads to the familiar error message when you try to use or install unsigned software: “[This app] can’t be opened because it is from an unidentified developer.” One change to Gatekeeper that arrived in macOS Catalina a few years back was that software is checked for malware and other issues every time it runs, rather than just the first time you install it.

For maximum protection, GateKeeper can be set to only allow software to be installed if it was downloaded from the Mac App Store. Or you can set it to allow you to install software from the web, but from verified developers only.

You can adjust these settings via the Security & Privacy section of System Preferences:

1. In Security & Privacy, select the General tab. 
2. Choose from the options underneath Allow Applications Downloaded From.
3. Choose App Store or App Store and Identified Developers.

The safest option is App Store only, but if you also want to be able to install legitimate software from the web then App Store and Identified Developers is the best plan. There used to be a further option to disable the feature by choosing ‘Anywhere,’ but this option is no longer available.

All software downloaded via the App Store is signed, but should you attempt to open an app you’ve downloaded from the web that isn’t signed, you’ll see a Gatekeeper warning like the one below:

This may mean you’ve almost installed malware. On the other hand, of course, it may be a legitimate app. In which case (and if you’re sure) you can bypass Gatekeeper’s protection and install it.

To do so, go to the Finder and locate the app there. Now hold down Ctrl when you click on the app, and then select Open. This will mark it as being trusted. For more details, read how to open an app from an unidentified developer.

Being able to download unsigned software might sound like a benefit, but it essentially enables you to bypass the protections offered by Gatekeeper. That’s a mixed blessing, and more and more malicious apps are instructing users to do exactly this when they are installed.

Sandboxing and related protections

Software that is approved by Apple is also sandboxed, which means apps do only what they’re intended to do. App sandboxing isolates apps from the critical system components of your Mac, your data and your other apps, so they shouldn’t be able to do any damage. It doesn’t protect you from malware getting into the system, but it does limit the extent of what the malware can do once it’s in there.

The main problem here is that while apps sold on the Mac App Store have to be sandboxed, other Mac apps don’t.

However, even without app sandboxing, there are related features built into macOS that should still stop apps snooping on your data. Since macOS 10.15 Catalina in 2019 it has been a requirement for all Mac apps to get your permission before they can access your files. macOS will also ask for your permission before an app can access the camera or microphone, or log what you type.

Another change that arrived with Catalina is that macOS itself is now stored on a separate disk volume. This means that your important system files are all completely separate and therefore more challenging to access. Apps can’t get to your system files where they could cause problems.

Security updates

Apple regularly issues security updates for the Mac. While these can serve to demonstrate that the Mac isn’t infallible, with Apple all too frequently having security flaws pointed out to it, they are generally issued promptly.

Less pleasingly, these security updates have generally been issued as part of a larger macOS update: for example, macOS Monterey 12.2.1 closed a security vulnerability in WebKit that would have made it possible to execute malicious code. Because these security fixes were issued as part of a macOS update, which often requires the computer to reboot during the install process, Mac users may be less likely to install the update promptly, even though these updates can be set to install automatically.

Since the launch of Ventura, however, Apple has started separating out the security updates from wider macOS updates and rolling them out automatically. This way the update can happen in the background, without a restart.

Password protection and Passkeys

Apple improved the way users can manage passwords in macOS Monterey and also made some changes to two-factor authentication. You can find all your Passwords in System Preferences > Passwords. You just need to unlock it with your main password to see every other password you have. (You can also view this information on your iPhone in Settings > Passwords.)

In Monterey a new authenticator was added, so you can set up verification codes instead of using an authentication app. To add a setup key you need to click on a password and then choose Enter Setup Key, which you should be able to obtain from the provider. Once input the 2FA verification codes should automatically fill.

In macOS Ventura Apple moved from passwords to passkeys. Apple explains: “Passkeys use iCloud Keychain public key credentials, eliminating the need for passwords. Instead, they rely on biometric identification such as Touch ID and Face ID in iOS, or a specific confirmation in macOS for generating and authenticating accounts.” Passkeys are more secure, according to Apple. Essentially your device will hold one part of a cryptographic key pair and the other part will be stored by the website or service you’re logging into. Your device will authenticate you biometrically (with Touch ID or Face ID) and log you in. For more information, read How to use Passkeys.

Recording alerts

In macOS Monterey Apple added a Recording indicator in the menu bar so you’ll know if an app is recording you. A bit like the light that indicates the mic is in use on your iPhone.

Pasteboard alerts

Similarly, as of macOS Ventura, any app that wants access to your pasteboard has to request permission.

Safari protections

Anti-phishing technology in Safari will detect fraudulent websites. It will disable the page and display an alert if you visit a suspect website.

Anti-phishing isn’t the only way that Safari protects you when you’re surfing. Apple also allows users to prevent advertisers tracking them around the web. You can see a Privacy Report including details of all the cross-site trackers Apple has stopped from profiling you.

You’ll also notice that plug-ins such as Silverlight, QuickTime, and Oracle Java won’t run if they aren’t updated to the latest version, another way of ensuring your Mac is safe. And of course now that Adobe has discontinued Flash people should hopefully no longer fall for malware hidden in Flash Player.

Safari will also flag up weak passwords and make strong password suggestions when you open an account on a website. This strong password will be saved in your iCloud Keychain so you won’t have to remember it. It’s a lot safer than using the same password you always use. For more on this subject, read about How Apple plans to retire passwords.

In the past, one issue with Apple’s suggested passwords has been that sometimes they don’t match the website’s requirement. For example, a website may require one upper-case letter, one special character, one number and so on. As of the launch of Ventura, macOS allows users to edit suggested passwords so they meet these requirements.

New in Safari 15 were improvements to the Intelligent Tracing Prevention that arrived in Safari 14. Now web trackers won’t be able to see your IP address so they won’t be able to create a profile about you. Check this by choosing Safari from the Safari menu > Preferences > Privacy > Hide IP address from trackers.

Photo privacy

A few years ago there was a lot of bad publicity for Apple when celebrities reported that their iCloud photos had been stolen. (For more on this, read How to stop photo hacks on iPhone.) There have been a number of security enhancements in iCloud since this happened, and Apple has given users other ways to protect their photo privacy: for example, the ability to hide photos and albums. In Ventura, Apple expanded this so that hidden albums, and the Recently Deleted album, are locked by default, and only authenticated by Touch ID or Face ID.

Mail protections

macOS Monterey brought a new feature in Mail on the Mac. Mail Privacy Protection improves privacy for users. For example, it stops email senders from being able to track whether you’ve opened an email, or even determine your location from your IP address. Check that the feature is working for you by opening Mail > Click on Mail in the menu > choose Preferences > Privacy > and make sure Protect Mail Activity is selected. It should be by default.

There are additional Mail protections if you’re an iCloud subscriber. Hide My Email allows you to create an alternative email address that you can give out. The email will still be delivered to your inbox, but you can easily delete the alternative email later.

You can turn this on in System Preferences > click on Apple ID > and select Private Relay (currently in Beta). 

In Ventura Hide My Email was extended to third-party apps.

iCloud+ protections

If you’re an iCloud subscriber, you’ll be interested in a feature that arrived in Monterey (part of the upgrade from iCloud to iCloud+) called Private Relay. It’s a bit like a VPN in that it encrypts your network traffic and routes your DNS lookup requests through two servers, one of which is not controlled by Apple. However, it’s not a VPN, because it only works in Safari and obviously it lacks the other usual features of a VPN. (If you want a VPN, by the way, check out our roundup of the best VPNs for Mac. You may even be able to save some money if you take a look at our roundup of VPN deals, or try one of these free VPNs.)

You can manage your Private Relay settings in System Preferences > Apple ID > click on Options beside Hide my email. Here you will see any fake email addresses you’re using; just click on Turn Off if you want to stop those emails arriving. You can also change which email address they are forwarded to. 

Safety Check

A new feature in macOS Ventura is Safety Check, a feature that will allow anyone who is concerned that they are in danger from a person known to them to revoke any access they have granted to that person. So, for example, that person won’t be able to access their location, their photos, or anything else that could help them to be traced.

File encryption with FileVault

In addition to Gatekeeper, which should keep malware off your Mac, FileVault 2 makes sure your data is safe and secure by encrypting it.

If you’re concerned about someone being able to access the files on your Mac you can encrypt them using FileVault, which will mean only you can unencrypt them. Read our tips for keeping your mac secure, of which using FileVault is one.

Warnings about spyware

Apple announced in November 2021 that it would warn its users of state-sponsored espionage attacks, such as the well-publicised Pegasus spyware, on their iPhones, iPads and Macs. The notification will come via email or a message. The same warning will be displayed on the user’s Apple ID page at appleid.apple.com.

The warning will offer advice about how affected users can protect themselves against attack. There’s more information on Apple’s site.

Find My

Not every threat to your data comes from malware. Sometimes a criminal might get hold of your Mac, in which case Apple’s Find My service will come into its own.

The Find My app can relay the location of your lost or stolen Mac back to you. If you’re concerned that it might not be recoverable, you can wipe the contents of the Mac so that your data can’t be accessed. For more on this, read How to find a lost or stolen iPhone.

In addition, every Mac with an M1-series, M2-series, or T2 chip has an Activation Lock feature that means they can be bricked remotely.

When Apple’s security measures aren’t enough…

All the above is great, but unfortunately there have been cases where Gatekeeper has been bypassed because malware has got an approved developer signature. For example OSX/CrescentCore was able to bypass Gatekeeper because it was signed by a certificate assigned by Apple to a developer. It took Apple a few days to retract that certificate.

It isn’t only when malware gets a certificate from a registered developer. In the case of OSX/Linker, a zero-day vulnerability in Gatekeeper was being exploited.

Zero-day threats mean there are “zero days” to fix the vulnerabilities, although often a legitimate developer discovers the vulnerability and lets the developer know about it. There is usually a 90-day deadline for the fix to be made available. Some times the developer doesn’t act in time and the exploit is publicised.

Apple normally reacts quickly, although there have been cases where the company has ignored the identified vulnerability, such as when a teenager reported the Group FaceTime vulnerability that meant someone could listen in to a call and Apple failed to act. There’s more about how Apple reacts to security threats next.

When Apple is made aware of a threat the company usually issues a security update to the latest version of macOS and to the two versions prior to it. This way Apple will protect users from vulnerabilities and flaws in macOS that could be utilised by hackers.

Normally the advice would be to install the update immediately. However, for example a Sierra and High Sierra security update in July 2019 was subsequently pulled after people experiences problems after installing it.

How Apple responds to security threats

Despite the security measures Apple has in place, from time-to-time there are threats to the Mac.

Apple has its own security research team, but it depends on users and independent researchers to help by reporting any flaws they find in Apple products.

To this end, Apple has an incentive program that rewards such discoveries with payments of up to $200,000, depending on the seriousness of the flaw. But it was the last major tech company to set up such a scheme. (Microsoft set up its own bug-reporting incentive programme in 2013, and was itself criticised at the time for leaving it so late.)

On 4 August 2016, Apple security boss Ivan Krstic announced the Apple Security Bounty Program. “We’ve had great help from researchers in improving iOS security all along,” Krstic said. “[But] we’ve heard pretty consistently… that it’s getting increasingly difficult to find some of those most critical types of security vulnerabilities. So the Apple Security Bounty Program is going to reward researchers who actually share critical vulnerabilities with Apple.”

The top reward of $200,000 is given to those who discover vulnerabilities in Apple’s secure boot firmware components; for less critical flaws the bounties drop through a series of smaller figures to a bottom tier of $25,000. Wired has the details.

We imagine most Mac users will be pleased to hear that Apple has an incentive programme to encourage more widespread reporting of its vulnerabilities. Incentivising security researchers to let Apple know about a flaw instead of passing it on to hackers (which may still, sadly, be more lucrative) makes Apple products safer for everyone.

One such flaw was the High Sierra root bug, discovered on 28 November 2017. This flaw in macOS 10.13 could allow access to settings on a Mac without the need for a password. Apple immediately issued a statement confirming that it was working on a fix and an update was anticipated to be issued within days.

How to keep your Mac safe from malware

Apple does a lot to keep your Mac safe, but you have to work with it, installing updates when they arrive, not clicking on suspicious links in emails, not installing Flash, and so on. There are also some third party antivirus apps you could try – we have a complete guide to the best antivirus for Mac here.

Here are a few of the things you should do:

1) Keep macOS up to date

Despite what we said above about the security update Apple later retracted, normally the advice would be to install a security update as soon as possible.

Apple addresses flaws and vulnerabilities with the Mac by issuing updates to the Mac operating system, it is important to keep your Mac up to date. We advise checking regularly for OS updates remains a key part of a sound security strategy.

You can find out about the latest version of macOS here: macOS Ventura latest version information.

You can set your Mac to automatically update as soon as a new version of the operating system is made available. Follow these instructions to set that up:

How to automatically install macOS updates

1. Open System Preferences.
2. Click on Software Update.
3. Tick the box beside Automatically keep my Mac up to date.
4. Or, click on Advanced and choose from automatically: Check for updates, download new updates when available, Install macOS updates and Install app updates from the App Store.

How to automatically install High Sierra or older software updates

1. Open System Preferences.
2. Click on App Store.
3. Tick the box beside Automatically check for updates.
4. You can choose to download the newly available updates, if you want them to install automatically though you need to make sure the box beside Install macOS updates is checked.

How to manually install macOS software updates

If you’d rather not let your Mac automatically update, you should periodically check to see if there is an update to your version.

• In macOS High Sierra and earlier you can go to the Mac App Store and check for updates.
• In macOS Mojave and newer you need to go to the Software Update pane in System Preferences.

You may need to restart your computer once the update has downloaded. You can expect a typical 460MB download to take about 8 minutes (during which time you will still be able to work) but for a large update you will have to restart and install and that could take as much as 20 minutes, bringing the total install time to about 25 minutes in total.

For our in-depth guide to updating Mac operating systems, see How to update macOS.

2) Don’t connect to public Wi-Fi networks

Beware of connecting to a public Wi-Fi network as there may be someone spying who could gain access to your passwords and other private information, or you could have your session hijacked. Snoopers can set up their own Wi-Fi hotspot, pretending to be your hotel or coffee shop, then once you have connected they can grab any data you send over it. In the past there have been flaws detected in the OS that could allow access to your Mac, such as the SSL error in an earlier version of Mac OS X that meant it was possible for a hacker to access your machine if you were using public WiFi.

3) Don’t install Flash

Adobe discontinued Flash on 31 December 2020 with good reason. Intego, Malwarebytes and others recommended that you shouldn’t install Flash Player. Fake Flash Player updates have often been the means by which people install malware. For example, people want to watch or download a popular movie or TV series for free and they find a search result that leads to a request to update Flash Player in order to view the content. There is no need to install Flash Player now that HTML5 has made Flash obsolete. Now that Flash is no longer be supported the advice is simple: Don’t use Flash!

4) Keep Java up to date on your Mac

If you must use Java (which is also problematic) then make sure it’s up to date. Vulnerabilities with Java have highlighted the fact that there are cross-platform threats that even Mac users need to be aware of. Apple blocks Java by default, leaving it to the user to decide whether to install those tools. If you do need to update them be very careful where you download updates from!

5) Avoid falling foul of phishing emails

Protect yourself from phishing attacks not responding to emails that require you to enter a password or install anything. You could also use free software such as BlockBlock. That way even you were to carry out the steps to launch the malware, it would not be able to write files or mark itself as launching on startup.

6) Don’t fall for Facebook scams

Facebook scams are usually designed to harvest data about the most gullible people, so if it seems like it might be too good to be true it probably is and you’d be wise not to share it on Facebook. At best you might just look silly and those scammers will start to target you with more scams, at worse scammers can access your personal data and that of those you share their post with. So don’t click on a link just because a friend shared it and definitely don’t give out your personal data on Facebook.

Why you need to protect Windows users

One of the reasons why, regardless of how safe a Mac is from malware, we should run an antivirus is to protect our Windows using friends and colleagues. While it’s unlikely that your Mac will run any malware, there is possibly a more pernicious issue: You Mac could become the Typhoid Mary of Windows viruses, which is to say, you could be harboring viruses on your Mac that won’t effect you, but can be problems for Windows users.

4. Mac crashes.
5. Mac runs hot.
6. Mac speeds up for no reason.

If you think something suspicious is happening, open Activity Monitor and click on the CPU tab. Check what software is running – especially if something is hogging a lot of your resources.
