  • macOS 27 beta (Golden Gate) breaks the ability to boot Asahi Linux on Apple Silicon Macs.
  • Asahi Linux partitions become invisible in the boot picker and Startup Disk, preventing booting, though data remains intact.
  • Asahi Linux has filed a bug report with Apple and warns users to avoid updating to macOS 27 beta.
  • Users who have installed the beta are advised to keep a secondary macOS 26 or older installation to temporarily boot into Asahi Linux.
  • In related news, Linux 7.2 will add boot support for Apple M3 devices, but it's not yet ready for end-users.
