Apple has officially opened the doors to the public betas of iOS 27 and macOS 27 Golden Gate, and for the first time in a long while, the early buzz is very good. If you have been curious about what is coming to your iPhone or Mac this September, you can now try it yourself, for free, without needing to be a developer.
The public betas landed on July 13, 2026, right on schedule. According to AppleInsider, this covers iOS 27, iPadOS 27, macOS 27 Golden Gate, watchOS 27, visionOS 27, and tvOS 27. Practically the entire Apple software lineup at once.
What Is Actually New in iOS 27?
The headline feature is Siri AI. According to Engadget, the new Siri transforms from a basic voice-command tool into a fully conversational AI assistant. It can hold natural back-and-forth conversations, understand follow-up questions, analyse what is on your screen, and complete multi-step tasks inside apps. There is also a dedicated Siri app that stores your conversation history.
Beyond Siri, iOS 27 focuses on three core areas, as detailed by Macworld: new parental controls for child safety and screen time management, performance and interface refinements addressing dozens of long-standing user requests, and upgraded Apple Intelligence models that improve AI features throughout the system.
The public beta build is identical to Developer Beta 3, build 24A5380h, released the same day.
What About macOS 27 Golden Gate?
macOS 27 is named Golden Gate, after the famous strait in San Francisco, and it carries the same Siri AI features as iOS 27. You summon it through Spotlight using the familiar Command + Space shortcut. From there, Siri can search the web, dig through your photos, emails and messages to find things, and complete actions across different apps.
According to MacRumors, Visual Intelligence has also come to the Mac, meaning Siri can now look at whatever is on your screen and answer questions about it. On the design side, Golden Gate brings uniform toolbars, edge-to-edge sidebars, and more refined window shapes and menu bar icons, building on the Liquid Glass look introduced in 2025.
One important note for Mac users: according to Wikipedia’s macOS Golden Gate entry, Golden Gate requires an Apple Silicon chip (M1 or later). Intel-based Macs will not be able to run it, though Intel apps will still work through Rosetta 2.
How to Install the iOS 27 Public Beta
The process is straightforward. As outlined by MacRumors, here is what to do:
1. Go to beta.apple.com and sign up for free using your Apple ID.
2. On your iPhone, open Settings, tap General, then Software Update.
3. Tap Beta Updates and select the iOS 27 Public Beta option.
4. If you do not see it immediately, restart your iPhone and check again.
How to Install the macOS Golden Gate Public Beta
1. Sign up at beta.apple.com with your Apple ID.
2. On your Mac, go to System Settings, then General, then Software Update.
3. Toggle on the macOS 27 beta option and follow the prompts.
Should You Install It Right Now?
That depends on how adventurous you are. The good news is that early feedback on both iOS 27 and macOS Golden Gate has been unusually positive. One commenter on MacRumors described it as the most stable beta they had ever run, with no crashes and very smooth performance across all devices.
That said, both Apple and AppleInsider strongly advise against installing any beta on your primary device. The risk of data loss and app incompatibility is smaller in a public beta than in a developer build, but it is not zero. The safest approach is to test on a secondary device and always back up before installing.
When Does the Full Release Come Out?
Both iOS 27 and macOS Golden Gate are expected to reach the general public in September 2026, following Apple’s usual annual release cycle. The beta period running through July and August is Apple’s window to iron out bugs and gather feedback before the big launch.
If you prefer to wait for the stable release, September is not far away. But if you want a proper look at the next generation of Apple software, especially that new Siri, the public beta is now open to anyone.
