The latest version of macOS–Sequoia–arrived on Macs in September 2024, but the beta development continues and if you are a registered developer or registered as a public beta tester, you can continue to get the latest updates and try out new features still not available to the general public.

In this article, we’ll explain what’s in the latest beta, what you need to do to get your hands on a copy, 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 use the latest official release of macOS Sequois here’s how to update macOS on your Mac.

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.

Not that we recommend that you should get the beta if you aren’t a developer. Beta software tends to be buggy and a more stable public beta version is also available.

macOS developer beta: Latest version

• macOS Sequoia 15.0
• macOS Sequoia 15.1 release candidate released October 21

Foundry

The first version of the Sequoia developer beta of macOS 15 arrived after the WWDC keynote on June 10, 2024. Beta 2 arrived on June 24.

Notable additions to beta 2 were iPhone Mirroring, the ability to directly access an iPhone through the Mac. The Mac and iPhone connect wirelessly and users see the iPhone Home screen on the Mac. Users can click and use iPhone apps, iPhone app notifications can be activated, and the appropriate iPhone app launches. Users can also drag and drop photos and videos from the iPhone to the Mac. The iPhone audio will come through the Mac’s sound output, and iPhone notifications will integrate with the macOS notifications list. iPhone Mirroring works on all M-series Macs and Intel Macs that have a T2 Security chip. The iPhone and Mac need to be signed into the same Apple Account, and Bluetooth and Wi-Fi need to be enabled. iPhone Mirroring works on all M-series Macs and Intel Macs that have a T2 Security chip.

macOS public beta vs developer 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 are able to 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 verison 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.

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.

Before you download a few warnings:

• We strongly advise that if you aren’t a developer you don’t download the developer beta.

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 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.
