The Asahi Linux project,
which brings Linux support to Apple Arm-based Macs, has warned
its users not to upgrade to the macOS˙27 "Golden Gate"
beta.

Apple has changed how the boot picker and Startup Disk applications
detect valid OS boot volumes. When using either from macOS˙27, your
Asahi partition will not be visible! We believe this to be a bug, and
have filed a report (FB22994760).

If you have already upgraded to the beta and noticed that your
Asahi partition has disappeared, do not stress. Your Asahi partition
is still there, and you have not lost any data.

The Asahi Linux installer has been patched to prevent use with
macOS˙27 for now, but any users already bitten by the change will
need to use macOS˙26 to restore access to Asahi Linux.
