Asahi Linux warns users not to upgrade to macOS 27 beta
The Asahi Linux project,which brings Linux support to Apple Arm-based Macs, has warnedits users not to upgrade to the macOS27 "Golden Gate"beta.
Apple has changed how the boot picker and Startup Disk applicationsdetect valid OS boot volumes. When using either from macOS27, yourAsahi partition will not be visible! We believe this to be a bug, andhave filed a report (FB22994760).
If you have already upgraded to the beta and noticed that yourAsahi partition has disappeared, do not stress. Your Asahi partitionis still there, and you have not lost any data.
The Asahi Linux installer has been patched to prevent use withmacOS27 for now, but any users already bitten by the change willneed to use macOS26 to restore access to Asahi Linux.
