Computer Accessories, Mac

One of the joys of Touch ID on a Mac laptop is using Apple Pay without needing an iPhone or iPad at hand to validate a secure credit or debit card transaction. This was extended to M-series Macs with the Magic Keyboard with Touch ID, which allows a Mac mini, iMac, or Mac Studio to add Touch ID through a special wireless connection to an M-series Mac’s Secure Enclave module.

But some readers have found Apple Pay disabled. In  > System Preferences/Settings > Wallet & Apple Pay, macOS offers the explanation “Apple Pay has been disabled because the security settings of this Mac were modified.” Several different causes could be the root, and Apple omits one for M-series Macs in the document linked via a Learn More button in the pane–the company says it doesn’t apply, though I found in testing that it does.

Full Security on an Intel or M-Series Mac

To ensure Apple Pay works, system security must be set to Full Security on both Intel and M-series Macs. This requires restarting or starting up in recoveryOS and then using the Startup Security Utility to reset system security.

You may have downgraded security on an Intel Mac to boot off an external volume or to install some low-level drivers for third-party software. With an M-series Mac, the most likely reason is you enabled its Reduced Security mode to install a kernel extension required by some software that taps into low-level drivers, such as MacFuse or SAT SMART for drive monitoring.

With a reduced-security macOS startup, Apple may be unable to create the level of integrity it and the credit-card system requires for mobile payments that match the degree offered by a point-of-sale system accepting a chip on a card. If so, Apple Pay is disabled on the Mac. (Apple explains in technical detail how this relates to the M-series boot security policy process in this platform security document.)

There are separate paths on how to re-enable Full Security by Mac architecture type. Apple offers a full page walkthrough on reverting to Full Security with an Intel Mac with a T2 Security Chip. For an M-series Mac, look at the “Change the security policy” heading in this support document.

Other causes

Apple also suggests other causes:

• If you have a laptop, its lid must be open. This makes sense because how would you otherwise use the Touch ID sensor? There’s an exception: you can still use the sensor on a Magic Keyboard with Touch ID with an M-series Mac with the lid closed. (Apple doesn’t list this exception; I tested it, and it works.)
• A necessary security update may not have been installed. In the Software Update preference pane, click Advanced: the “Install system data files and security updates” box should be checked for automatic installation.
• Apple also notes more ambiguously that macOS disables Apple Pay “when it detects third-party software or malware that affects its ability to keep your payment information secure.”

You might wonder why Safari continues to allow you to fill in stored credit and debits cards from Safari > Preferences > Autofill if Apple Pay is disabled? Safari doesn’t perform a mobile payment transaction when it auto-fills card information—it just drops the information in without additional typing. If you’ve stored the Card Verification Code (CVC, also known as CVV and by the names), Safari will fill that in, too.

Credit-card processors that manage transactions for online retailers treat form-entered cards as among the most potentially fraudulent transactions; they don’t differentiate—nor do they have a way to—between browser auto-filled card details or those entered manually. Apple Pay mobile payments are among the least likely to be fraudulent because of the way the transaction is created and validated and are scored for risk accordingly.

Mac, MacOS

If you don’t want to wait to install the next version of macOS – which we now know will be called Sonoma after Apple revealed all the details at WWDC in June, you can join the beta program and try it out on your Mac before it is released to the public in September or October.

The developer beta of macOS 14 Sonoma is already available to download. This year the developer beta isn’t just available to developers who have paid to join Apple’s Developer Program (which costs $99/£79), Apple has opened it up to anyone who is a registered developer. We explain how to get a free developer account below.

The slightly more stable public beta version will be available for anyone to sign up for the public beta program around the beginning of July.

Even though macOS 14 is now in beta, the beta program is still running for macOS 13 with testers currently running macOS 13.5. If you would prefer to run that beta you can do so.

In this article, we’ll run through what you need to do to get your hands on the beta of the next version of the Mac operating system, how to install it, and what you should bear in mind if you don’t want to end up in a pickle. If you would prefer to wait for the full version of macOS Sonoma here’s how to update macOS on your Mac.

Update 7/5/23: Apple has released the beta 3 of macOS Sonoma to developers.

macOS Sonoma beta release date

The first version of the developer beta of Ventura arrived after the WWDC keynote on June 5, 2023 as expected. On July 5, Apple released the third developer beta.

The surprise was that Apple made this Developer Beta available to anyone who had registered as a developer, even if they weren’t a paid-up member of Apple’s Developer Program. As a result, people who have a basic free developer account are able to download the macOS Sonoma developer beta already, and we will show you how to register below.

Whether you should download the developer beta if you aren’t a developer is another question. We don’t recommend you install the developer beta if you aren’t a developer. Instead, our recommendation is to wait a few more weeks until the public beta arrives.

macOS Sonoma public beta release date and differences

The public beta of Ventura was released on July 11, 2022, so we expect a similar timescale for macOS Sonoma, perhaps July 10, 2023.

There are a few differences between the public and developer betas. The public beta is not the same as the beta that is released through the developer program.

Developers get updates to their beta first, and possibly more frequently. But you should keep in mind that betas are by nature not stable, and because the public beta comes after the developer beta it could be a little safer to install.

The most significant difference is probably the motive of the testers: Developers usually have the aim of ensuring their apps work when the updated macOS is released to the general public, while public beta testers are essentially helping Apple detect bugs and offering feedback on the features. Because of this developers may get to test new features not available in the public beta. 

If you want to get the public beta the first thing you need to do, if you haven’t already, is join Apple’s beta programs read this for more information: How to become an Apple beta tester.

How to get a free developer account

If you just want a free Apple Developer account so you can access the beta you can get this via Xcode or the Apple Developer app in iOS. Here’s how to do it via the Apple Developer app on an iPhone:

1. Get the Apple Developer App from the App Store. 
2. Open the app on your iPhone. 
3. Tap on Account. 
4. Tap on Sign In. 
5. Sign in using your usual Apple ID. 

If you wish to actually publish applications to the App Store or receive support, you’ll need to pay $99/£79 per year for a paid account. You can compare the free and paid accounts here.

How to get the macOS Sonoma beta

The Sonoma developer beta should show up on your Mac if you are running macOS Ventura 13.4 or later, have paid $99/£79 to enroll in Apple’s Developer program (here) or if you have a free developer account (follow the instructions above).

When the Public Beta becomes available it will also show up on your Mac in macOS Ventura 13.4, as long as you have signed up for the Public Beta program on Apple’s beta webpage, signed the NDA, and enrolled your Mac.

Before you download a few warnings:

• We strongly advise that if you aren’t a developer you don’t download the developer beta.
• We also strongly recommend that you back up your Mac before you upgrade to the Sonoma beta.
• We recommend that you do not run Sonoma on your primary Mac; ideally, you run it in a separate volume. This should minimize any risks to you.

If you are running macOS Ventura 13.4 or later:

1. Open Software Updates on your Mac. (System Settings > General > Software Updates.)
2. You should see two options: Automatic Updates and Beta Updates. Click on the (i) beside Beta Updates.
3. You can now turn on Beta Updates (if they weren’t already on).
4. Choose the beta you want to download.
5. If your developer account is tied to a different Apple ID to your usual one you can change that here.
6. Click Done.
7. Now your Mac will Check for updates and eventually show the Sonoma Developer Beta as an upgrade. Click on Upgrade Now.

If you are running macOS Ventura 13.3 or earlier:

Apple changed the way it delivers betas in Ventura 13.4. If you aren’t yet running that version of macOS you will need to download the macOS Developer Beta Access Utility or macOS Public Beta Access Utility.

If you were already running an earlier macOS Public Beta you’ll find the new macOS beta as an upgrade via Software Update. Just click on Upgrade Now. You may have to update to the latest version of your current beta before you can do so, if not follow the steps below to get the beta access utility.

1. If you are enrolled in the Developer Program, go to Apple’s beta download page. Click on Install Profile to download the new macOS Developer Beta Access Utility to your Mac.
2. If you are enrolled as a public beta tester, download the macOS Public Beta Access Utility.
3. Go to Downloads on your Mac and click on the macOS Beta Access Utility to open it.
4. Double-click on the dmg file and the installer will run.
5. Once the new macOS beta is installed Software Update will check to see if there are any updates. Click Update and the latest version will download.
6. You’ll see a prompt to install the latest macOS beta, click on Continue.
7. Agree to the Ts&Cs (more on them below).
8. Click Install.

How to update macOS beta versions

Once you are running the beta the updates will come through to your Mac automatically, you just need to click to install.

1. You will receive a notification when the next update to the beta is available.
2. Updates will be available via Software Update (in System Settings/System Preferences)

Everything else you need to know about beta testing

That covers how to get the betas, but once you have them what can you do, and what should you do? We’ll cover that below.

Is the macOS beta stable?

By its nature, a beta has the potential to be unstable. Therefore it’s not advised that you install it on a Mac that you rely on. If you have a second Mac that isn’t mission-critical then install it there. We strongly recommend that you don’t risk all by putting the macOS beta on your primary macOS, especially not in the early days of the beta development. 

If you don’t have a second Mac there are a couple of ways you could run macOS beta on your Mac without running the risk of losing data or finding your Mac stops working:

• We recommend installing it on a partition – which these days is really a volume (and is much easier to create than a partition was). Read about how to do that here: How to dual-boot Mac: Run two versions of macOS on a Mac.
• Alternatively, you could install the macOS beta on an external drive and run it on that.

We discuss the safety of the macOS beta and the risks you might be taking in more detail in a separate article.

If the stability of the beta worries you then you are probably better off waiting until the final version is out, or at least waiting until testing has been happening for a few months before getting the beta.

How to prepare your Mac for the beta

Update your software: We recommend you have the latest full version of macOS installed, although Apple says that the macOS Developer Beta Access Utility requires macOS 10.8 or later.

Make space: We’d recommend at least 15GB of available space because the macOS betas tend to be very large. If you end up requiring more space read: How to free up space on Mac. Note that we always recommend that you have at least 10% space free on your Mac at any time, so if you don’t have that expect problems!

Back up: Before you install a beta on your Mac you should make a backup of your data and files. You can find out how to use Time Machine to back up your Mac. We also have a round-up of suitable backup solutions.

How to send feedback to Apple

Should you come across an error or a bug you should use the Feedback Assistant app to provide feedback to Apple. Launch the app and follow the appropriate steps, selecting the area about which you’re providing feedback and then any specific sub-area. Then describe your issue in a single sentence, before providing a more detailed description, including any specific steps that reproduce the issue. You’ll also be able to attach other files.

You’ll also have to give permission for the Feedback Assistant app to collect diagnostic information from your Mac.

It won’t always be obvious whether something is a bug or just not as easy to use as you might have hoped. Either way, if your feedback is that something appears to work in an illogical way, Apple will want to know that.

If you are having trouble with a third-party app you can let Apple know by reporting it through the 3rd-party Application Compatibility category in the Feedback Assistant. However, we’d suggest that you also provide feedback to the app’s developer who will no doubt be grateful.

Will I be able to update from macOS beta to the final version?

Beta users will be able to install the final build of the OS on release day without needing to reformat or reinstall.

Can I talk about the beta publicly?

According to Apple and the license agreement all beta testers must agree to, the beta is “Apple confidential information”. By accepting those terms, you agree not to discuss your use of the software with anyone who isn’t also in the Beta Software Program. That means you can’t “blog, post screenshots, tweet, or publicly post information about the public beta software.”

However, you can discuss any information that Apple has publicly disclosed; the company says that information is no longer considered confidential.

How to downgrade from the macOS beta

You can always revert to an earlier version of macOS, though depending on how you back up, it’s not necessarily a painless process.

Start by making sure the data on your drive is backed up, then erase the drive and install the latest public version of macOS. When you first startup your Mac you can use the Migration Assistant to import your data from the backup. Here’s a more detailed tutorial on downgrading from the macOS beta we also have a tutorial on downgrading to an older version of the Mac OS.
