Asahi Linux warns users not to upgrade to macOS 27 beta
[Posted June 9, 2026 by jzb]
The Asahi Linux project,<br>which brings Linux support to Apple Arm-based Macs, has warned<br>its users not to upgrade to the macOS 27 "Golden Gate"<br>beta.
Apple has changed how the boot picker and Startup Disk applications<br>detect valid OS boot volumes. When using either from macOS 27, your<br>Asahi partition will not be visible! We believe this to be a bug, and<br>have filed a report (FB22994760).
If you have already upgraded to the beta and noticed that your<br>Asahi partition has disappeared, do not stress. Your Asahi partition<br>is still there, and you have not lost any data.
The Asahi Linux installer has been patched to prevent use with<br>macOS 27 for now, but any users already bitten by the change will<br>need to use macOS 26 to restore access to Asahi Linux.
