The '27' era from Apple is nearly upon us, bringing with it the arrival of macOS 27. While this forthcoming update might not seem as packed with revolutionary new features as some earlier iterations, it introduces one significant addition: alongside various quality-of-life enhancements, macOS Golden Gate integrates major advancements in Apple Intelligence, including the new Siri AI. Personally, even if the primary benefit of upgrading to macOS 27 is simply that my M1 iMac runs a bit more fluidly, I would be satisfied. These new updates are not officially available to the public yet; they are expected to be released sometime in the fall for all supported hardware. That said, if you have a compatible Mac, you do not have to wait until then to run macOS Golden Gate. Since the WWDC conference in June, Apple has been beta testing these updates with registered developers, meaning you can try macOS 27 immediately if you are comfortable assuming the risks.
Understanding the Risks Before You Install
It is tempting to get an early look at fresh features, especially when they are as high-profile as the new Siri AI. However, before installing the macOS 27 beta, it is crucial to recognize the potential pitfalls. Beta software is essentially unfinished, which means it may ship with bugs or glitches that would not normally be present in a stable public release. You might install the beta and find your Mac works perfectly, or you could encounter a critical issue that hinders your ability to use your computer for daily tasks. It is effectively a gamble.
The caveat here is that the developer beta is currently in a much safer state than it was at its initial launch. Apple has spent approximately a month refining these updates with developers before opening them to a broader audience, so most of the overt or critical bugs have likely been identified and patched. Even so, the macOS 27 developer beta is not entirely free of potential glitches. You must ensure you back up all important data before starting the installation. Confirm that all your photos, documents, and messages are saved to a secure location outside of your standard iCloud backup, just in case you experience data loss during the process. For most users, I would recommend waiting until the public beta, which Apple mentioned will arrive sometime in July, as it offers a safer experience for those looking to mitigate the risk of major software failures.
Which Macs Are Compatible With macOS 27?
While every iPhone that supports iOS 26 is also compatible with iOS 27, the rules are different for the Mac lineup. Even if your machine runs macOS 26 today, there is no guarantee that it will support macOS 27. In fact, this year marks Apple's formal departure from Intel, as none of its Intel-based Macs are supported by macOS 27. The official list includes
- MacBook Neo
- MacBook Air with Apple silicon
- MacBook Pro with Apple silicon
- iMac with Apple silicon
- Mac mini with Apple silicon
- Mac Studio
- Mac Pro with Apple silicon
Essentially, if your Mac uses a chip with an 'M' designation (e.g., M1, M5), it is compatible with macOS 27.
How to Install the macOS 27 Developer Beta
If you are comfortable with the risks associated with developer software, your first step is to enroll your Apple Account in the developer program. There used to be a $99 paywall for this, but there is now a free option for anyone who simply wants to access the developer beta. Once you have enrolled, follow these instructions
- Navigate to System Settings.
- Select General, then click Software Update.
- Click the (i) icon located next to 'Beta Updates.'
- Switch the setting from 'Off' to 'macOS 27 Golden Gate Developer Beta.'
- Hit 'Done,' then follow the on-screen prompts to download and install the update.
