How to download the macOS 27 developer beta and which Macs support it

At WWDC 2026 Apple announced macOS 27 'Golden Gate,' due this fall. The update focuses on performance improvements, visual design refinements and a redesigned Siri. The developer beta is available now, but it is intended for developers — features may be unfinished, buggy or underperforming.

Apple typically releases the public beta in July; do not install the developer beta on your primary Mac and back up your data before making system-wide changes. Golden Gate ends support for Intel-based Macs, so you need Apple Silicon. Compatible models include MacBook Air M1 and later; MacBook Pro M1; MacBook Neo; iMac M1 and later; Mac mini M1 and later; Mac Studio M1 and later; and Mac Pro M2/2023 and later.

To access the developer beta, register as an individual on Apple's Developer site with your Apple account (membership costs $99/year). Then enable beta updates on your Mac: System Settings > General > Software Update, click the (i) icon next to 'Beta Updates', choose 'MacOS Developer Beta', click Done, then Update Now.
