Every year, Apple updates the Mac operating system. The current version of macOS is macOS 15.5, but development of macOS 26 (not macOS 16) is well underway.

Apple runs a beta program, which means developers and registered public testers can try out new features before they are released to the general public later in the year.

The beta process doesn’t stop with the full release of macOS in the fall. After macOS 15 Sequoia arrived on Macs in September 2024, development continued with new features rolled out every couple of months. The same will be true of the macOS 26 development cycle.

In this article, we’ll explain what you need to do to get your hands on a copy of the new beta of macOS 26, how to install it, and what you should bear in mind if you want to avoid problems. (If you would prefer to use the latest official release of macOS, here’s how to update macOS on your Mac.)

Update September 2, 2025: Apple released macOS 26 developer beta 9.

macOS beta: Latest version

The most recent version of the macOS 26 Tahoe developer beta is beta 9. It was released on September 2, 2025.

Following WWDC 2025 on June 9, the macOS 26 developer beta is now available to download for those signed up to the program. The “macOS 26” name is part of a coherent annual naming system along with iOS 26 and iPadOS 26.

macOS beta: Public beta release date

Apple released the macOS Tahoe public beta on July 24, 2025. Version 5 of the public beta arrived on August 25.

macOS beta: Next beta update

New betas tend to arrive every one to two weeks, and more frequently as the full release data approaches.

The beta testing program will continue to run after the new macOS 26 software launches in September or October 2025, with Apple continuing to roll out new features.

How to get the macOS beta

To get the developer version of the macOS 26 beta, you need to be running macOS Sequoia and be registered for Apple’s developer program, either having paid $99/£79 to enroll in Apple’s Developer program (here) or with a free developer account (follow the instructions below for how to register for that).

Alternatively, if it’s the public beta you are after, you just need to sign up for the Public Beta program on Apple’s beta webpage, sign the NDA, and enroll your Mac. Details of how to do that are below.

As long as you are a registered developer or enrolled in the public beta program, when the relevant macOS Beta becomes available, it will also show up on your Mac.

Before you download the beta, 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 macOS beta.





• We recommend that you do not run the macOS beta on your primary Mac; ideally, run it in a separate volume. This should minimize any risks to you.

How to get a free Apple 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 register for the macOS public beta

The macOS public beta is accessible to anyone with a valid Apple ID.

• To register, go to the Apple Beta Software Program page.





• Select the “Sign Up” option.





• Sign in using your Apple ID.





• Follow the on-screen prompts to complete the registration process.





• Enrol the Mac you wish to run the beta on via this Apple page.

How to download macOS beta

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: public or developer.





5. If your account is tied to a different Apple ID than your usual one, you can change that here.





6. Click Done.





7. Now your Mac will check for updates and eventually show the latest macOS Beta as an upgrade. Click on Upgrade Now.

Do I need the macOS Beta Access Utility?

Only 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 in order to download betas.
