Apple has made the first macOS 27 Golden Gate public beta available for testing before the new Mac operating system's official release in the fall. Keep reading to learn whether you should install it on your Mac, and if so, how to go about it.

Getting access to the macOS Golden Gate public beta is simple, and can be done by enrolling your Mac in Apple's free Apple Beta Software Program. The steps you need to complete to install the software on your Mac are provided towards the end of this article, but before you jump ahead, here are a few things worth considering.

Should I Install macOS Golden Gate Public Beta?

With macOS Golden Gate, Apple includes the same Siri AI features as iOS 27 and iPadOS 27, accessed through Spotlight with the Command + Space keyboard shortcut. Siri can search the web, find information in your photos, emails, and messages, answer questions about what's on your screen with Visual Intelligence, and complete actions within and across apps. A dedicated Siri app also supports ongoing conversations.

Apple has also refined the Liquid Glass design introduced last year. A new transparency slider lets you adjust the overall system effect, while updated opacity improves readability by better diffusing complex content. Additional interface refinements also add depth and separation, making it easier to identify the active window. There are a lot more improvements beyond the above, so the availability of the public beta will no doubt generate a lot of interest among Mac users.

But before you commit, bear in mind that Apple does not recommend installing macOS beta updates on your main Mac. However stable you may have heard it is anecdotally, this is beta software, which means there are almost certainly bugs and issues that can prevent certain software from working properly or cause other problems with the system. Indeed, one of the reasons that Apple releases the beta early is so that users can feed back problems and help Apple debug them. If you have a spare Mac hanging around, by all means use that, otherwise consider holding off until the general release in the fall.

Is My Mac Supported?

The update confirms the end of Intel Mac support. Apple said last year that macOS Tahoe would be the final release to run on pre-Apple silicon machines, and macOS 27 makes that official – you'll need an Apple silicon Mac to install it.

Here are the Macs compatible with macOS Golden Gate:
  • MacBook Neo (2026)
  • MacBook Air with Apple silicon (2020 and later)
  • MacBook Pro with Apple silicon (2020 and later)
  • iMac with Apple silicon (2021 and later)
  • Mac mini with Apple silicon (2020 and later)
  • Mac Studio with Apple silicon (2022 and later)
  • Mac Pro with Apple silicon (2023 and later)
Four models that ran macOS Tahoe didn't make the cut this year. They include the MacBook Pro (16-inch, 2019), the MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), the iMac (2020), and the Mac Pro (2019).

Don't Forget to Back Up Your Mac

Be sure to back up your Mac using Time Machine before installing the software using the method, otherwise you won't be able to revert back to the previous version of macOS if things go wrong.

How to Install macOS Golden Gate Public Beta

  1. Head over to Apple's Beta Software Program website and sign up using your Apple Account credentials, then agree to the terms and conditions if required.

That's all you need to do. The installation process will complete just like a standard macOS update, so sit back and let the installation finish, after which your Mac will boot directly into the macOS Golden Gate beta.

I tried developers version on my 14” M1 pro. I know that beta can make battery life worse and such. But I had same problem with 26 betas and final versions. So, I decided to clean install Sequoia. Better battery life and smoother performance. Wish I could do the same with my iPhone and ipad.

is there a way to get the ISO so i can test it as a VM via parallels?

edit: found the ipsw, but doesnt seem to be working currently on parallels. might need to wait for an update for it.

Installed on 16” M4 and everything runs great, except the calendar, which doesn’t sync. Error message is “not connected to server”. Other than that, Golden Gate is amazing.

not sure how deployment with ipsw works but presumedly one could add another volume to existing apfs container and install it alongside your current boot.
 
I’d install it on my new M5 MBA, but I think I prefer to wait until the system is well polished and rounded up, which usually happens by the .2 or .3, during holidays, and stay on a stable macOS 26.6 until then.

However, I think I will start ditching the clean install tradition, as it forces me to dump everything to an external drive and reinstall the apps afterwards… I think I will just perform updates except when a whole new version arrives, like it’s the case for GG.

I’d like to know how to perform an install of the whole macOS system without erasing the SSD, though. I’ve never liked OTA updates that just download a piece of the operating system, and I’m not sure how does it work on macOS…

just installed Golden Gate on my M1 Macbook Air, but needed to patch Adobe Creative Suite to have it working again
 
Someone who has installed it, can you confirm whether there is an issue with using Spaces? I saw there might be an issue with freezing when moving between desktops/fullscreen apps so if there is an issue I'd prefer to hold off on beta till addressed.
 
I’ve got it running as a second install and I’ve experienced quite a few app crashes, some apps not working properly at all, menu bar / menus not working properly on a dual monitor setup, app launcher not working. Just a few things off the top of my head.

It’s mostly stable, but it’s definitely a beta and there’s more than a few times I needed to reboot into Tahoe to get work done.

Had Beta 1 and 2 running on an external drive connected to my M4 Mini which had Tahoe running on the Internal drive. Both Beta versions ran ok as Betas go but Apple Intelligence was not available on external drives so I decided to be foolhardy and upgraded Tahoe to Beta 3 which I would guess is the same as the Public Release.

The Upgrade went ok but on running 'First Aid' in Utility, I saw a lot of errors in at least 2 volumes which could not be corrected. My next step was a clean installation by completely formatting the main drive and clean installed GG Beta 3 which I am happy to say went without any problems.

The few apps that I use are functioning ok apart from Logitech Options for my keyboard and mouse whereby some of the functions do not work. Also although Apple Intelligence is installed, it does not say Siri Apple Intelligence in the 'System Settings' sidebar as it did in Tahoe so I don't know if that is intentional or a bug.

BTW after running 'First Aid' with in installation, all volumes are free from errors.
If anyone is wondering why I took the chance and installed it on my main drive at this stage, I gained my bravery (fool hardiness) from coming off the many years of running a Hacintosh, if you know, you know (lol)

PS. As a side note I love this Wallpaper I am using.
Cheers.
