Apple Releases macOS 27 Golden Gate Beta 4: What’s New and How to Install

Apple has released macOS 27 Golden Gate beta 4 to registered developers for testing. The latest build arrives as Apple continues refining the major macOS update before its public release later this year.



The update is available over the air on compatible Macs enrolled in the developer beta program. Since beta software can contain bugs, users should back up important files before starting the installation.



How To Install



Developers can download the update through the Software Update section:




Back up your Mac using Time Machine or another backup method.



Open the System Settings app.



Select General and click Software Update.



Click the information icon next to Beta Updates.



Select macOS 27 Developer Beta.



Return to the Software Update screen.



Click Upgrade Now to download and install beta 4.




A free Apple developer account linked to the Mac is required to access the developer beta.



What’s New in macOS 27 Golden Gate Beta 4



Apple has not announced any major user-facing features specifically added in beta 4. The update appears to focus on fixing bugs, improving performance and making existing macOS 27 features more stable.



Some areas users should check after installing the update include:




Siri AI stability: macOS 27 introduces a more conversational Siri experience with expanded Apple Intelligence features. Beta 4 should continue improving its performance and reliability.



Liquid Glass design: Apple is refining transparency, typography, navigation bars and other visual elements across apps and system menus.



System performance: The latest beta likely contains under-the-hood improvements for app launches, animations and general system responsiveness.



App compatibility: Developers can use beta 4 to test their apps against the latest macOS 27 APIs and identify problems before the final release.



Bug fixes: The update should address problems reported in earlier builds, although Apple has not provided a complete public list of fixes.




More changes may appear as developers continue testing the update. Apple plans to release macOS 27 Golden Gate to compatible Mac users later this year.
