Apple has released macOS 27.2 Golden Gate developer beta 1 to registered developers. The update carries build 26B5086k. Apple’s release notes focus on two known Mac issues and StoreKit Testing changes for developers rather than a new user-facing feature.

Back up a Mac before installing pre-release software. Apple recommends using beta software on a secondary system, device, or Mac partition, rather than a machine required for everyday work.

How to update to macOS 27.2 beta 1

  1. Open the Apple menu and choose System Settings.
  2. Select General in the sidebar, then choose Software Update.
  3. Click the information button next to Beta Updates and select macOS 27 Developer Beta if necessary.
  4. When macOS 27.2 beta appears, click Update Now and complete the onscreen installation steps.

All changes in macOS 27.2 beta 1

  • Notification permission issue after a clean install: Apple says some apps, including Calendar, Maps, Find My, Home, and Weather, might not ask for notification permission after a clean installation.
  • Shortcuts known issue: Describe a Shortcut can fail with a “Something went wrong. Try again later.” message.
  • StoreKit Testing fixes: Apple lists fixes to introductory-offer eligibility, storefront and locale changes, and purchase dialogs in the Xcode test environment. These are developer-testing changes, not a list of fixes for Mac apps.
  • StoreKit Testing known issue: purchasing a subscription bundle member can allow an unbundle action instead of showing the expected error in testing.

Apple’s macOS 27.2 release notes do not identify additional consumer-facing features in beta 1. If you’ve already installed the update, let us know your experience in the comments.
