Anyone can run the macOS beta, but to do so, you do need to register for either the developer beta, the public beta, or both.

Apple offers both developer and public beta programs for macOS, enabling all interested users to test pre-release versions of the operating system. While both betas provide early access to new features, they cater to different user profiles based on technical expertise and risk tolerance. Beta software tends to be buggy so the more stable public beta version may be preferable, but even that will not be bug-free.

In the past, the developer beta was only available to developers who had paid to join Apple’s Developer Program (which costs $99/£79). However, for a couple of years now, Apple has opened up the developer beta to registered developers with free developer accounts. We explain how to get a free developer account below.

If you decide you no longer want to run the beta version of macOS read this: How to remove the macOS beta.

Since 2023, the Developer Beta has been available to anyone who registers as a developer, even if they aren’t a paid-up member of Apple’s Developer Program. As a result, people with a basic free developer account can download the new macOS developer beta (we 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 use the public beta (the first version of which usually arrives in July).

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. The public beta typically launches after the developer beta has undergone initial testing and refinement

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.

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 Mac, 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.

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 25-30GB 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.

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.

Beta users can move to the finished release once its build is newer than – or equivalent to – the beta installed. Read: How to leave the macOS beta.

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.

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 start up 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 and we also have a tutorial on downgrading to an older version of the Mac OS.

Yes, the macOS beta is free to download for both developers and the general public. Apple offers two distinct tracks for testing pre-release software: the Developer Beta and the Public Beta, both of which are now accessible without a paid subscription.

Yes, you can go back to the stable version of macOS from a beta, but the complexity of the process depends on whether the final version of that software has been released yet.

If you are running macOS 27.2 beta and want to return to the current public release of macOS 27, simply turning off Beta Updates will stop future beta installations, but it will not immediately downgrade the Mac. To return before Apple releases an equivalent public build, you may need to erase the Mac and reinstall macOS, then restore data from a backup made before installing the beta.

Installing a macOS beta on your primary computer is generally not recommended due to the inherent risks of using unfinished software. While beta programs offer early access to new features, they are designed for testing and often contain significant bugs that can disrupt your daily workflow.

You do not need a paid Apple Developer account to install the macOS beta. While access to developer betas was previously restricted to those paying a $99/£79 annual fee, Apple changed this policy in 2023 to allow anyone with a free developer account to access these builds. Alternatively, you can join the Public Beta program, which is also free and accessible to anyone with a valid Apple ID.

New macOS beta versions are typically released every one to two weeks, with the frequency increasing as the final public release date approaches. The beta updates refine features and address bugs identified by testers.

The beta is generally safe to test, but it may contain bugs that cause crashes, poor battery life, app compatibility issues, or data loss. Always back up your Mac before installing.

Many apps will work normally, but some third-party software may crash, perform poorly, or not launch at all until developers release updates.
