download macOS – Apple’s macOS 27 “Golden Gate” developer beta is available following WWDC 2026. The catch: it’s reserved for developers, requires a Mac with Apple Silicon, and Apple still warns against installing it on a main machine. Here’s how to check eligibility, download
When WWDC 2026 ended, one thing became clear for Mac developers: macOS 27 “Golden Gate” wasn’t just a future promise. The developer beta is available now—meaning anyone building or testing apps can get their hands on the latest changes before the public ever sees them.
The release is mostly aimed at performance improvements and visual design optimizations. with one headline feature standing out: a redesigned Siri. Still. Apple’s beta comes with the kind of uncertainty that developers expect—this stage is technically reserved for developers to test their apps. and features could be unfinished. buggy. or underperforming. Apple typically releases the public beta in July. but if you’re not paying for access. waiting may be the safer move.
There’s also a simple message Apple has repeated in its own beta guidance: don’t treat this like everyday software. Back up your data before making system-wide changes, and—especially—don’t download beta software on your daily driver Mac.
To be able to even try macOS 27 “Golden Gate,” your Mac has to be ready for the shift Apple is making away from Intel. Golden Gate marks the end of Apple’s support for Intel-based Macs, so you’ll need at the bare minimum a device running Apple Silicon.

How to download the macOS 27 developer beta
Getting the developer beta isn’t complicated once you’re eligible, but it does require developer access.
First, register as a Developer. Go to Apple’s Developer site and register as an individual with your Apple account. The membership costs $99/year. If you only want to “take a sneak peek” at new features, the guidance is straightforward: wait until the public beta opens in July.
Then, enable the beta update channel on your Mac.
On your Mac, go to System Settings > General > Software Update. Click the (i) icon to the right of “Beta Updates.” In the window that pops up, open the “Beta Updates” menu and select “MacOS Developer Beta.”
Click Done, then choose “Update Now.”
Before you install: the practical warnings
Apple Beta program guidance is clear about what to do before installing any beta software version. Back up your device and personal information. Don’t install beta software on a daily driver machine because it’s likely to have bugs and glitches.
And remember why this version exists in the first place: the Developer Beta is made for devs to test new features and share feedback to improve iOS.
When macOS 27 will be released
Apple released the macOS 27 developer beta during WWDC 2026. The public beta is expected to be released in July, with the general release of macOS 27 likely arriving in September—following the iPhone event where Apple announces new hardware.
Once the public beta arrives, installing it should follow the same route: System Settings > General > Software Update, then click the (i) icon to the right of “Beta Updates,” and look for an option for the MacOS 27 Public Beta.
If something breaks, Apple gives you a built-in way to report it. The macOS public beta comes with its own built-in Feedback Assistant app, which you can open from the dock. If you encounter something that doesn’t work—or you have feedback about any part of the OS—you can communicate directly with Apple via that app.
And while macOS 27 is drawing the spotlight right now. Apple’s timeline also points to iOS 27 next: the public release of iOS 27 is expected this September. iPhone users will be able to upgrade after it’s available depending on carrier, region, and local restrictions. The path is Settings > General > Software Update, then download when the option appears.
For now, macOS 27 “Golden Gate” is in developers’ hands. The safest bet is also the simplest one: back up first, verify eligibility, and don’t put this on the Mac you rely on every day.
