The Asahi Linux team issues a warning to Apple Silicon users not to install the macOS 27 beta, saying recent macOS changes make Asahi Linux partitions effectively invisible to the macOS boot process. Developers report that alterations to Apple’s boot picker and the Startup Disk application prevent Linux from being selected or booted after upgrading, even though the underlying Asahi partition remains in place. The team tells users who want to test macOS 27 to first install a secondary copy of macOS 26, or to install macOS 27 on a separate secondary volume. They also update the installer behavior to avoid installations that would run into the macOS 27 boot-picker problem for the time being. If users already upgraded and find the Asahi partition missing from macOS tools, the team says they should not assume data loss, stating the partition still exists. The Asahi team says it has filed a bug report with Apple and adds that it will not support users who installed the macOS 27 beta without ensuring at least one stable macOS version is present.

- Asahi Linux developers warn against upgrading Apple Silicon systems to the macOS 27 beta.
- They say macOS 27 changes to the boot picker and Startup Disk app make Asahi partitions invisible, preventing Linux from booting.
- The Asahi team states the Asahi partition remains on disk even if it is not visible after upgrading.
- They recommend installing a secondary stable macOS (such as macOS 26) or using a secondary volume for macOS 27.
- The team reports filing a bug report with Apple and says it will not support users who upgrade without a stable macOS installed.
The Asahi Linux team is warning Apple Silicon users not to upgrade to the macOS 27 beta because Apple's changes to the boot picker and Startup Disk app make Asahi partitions invisible, preventing Linux from booting. The Register reports: The team added: "If you insist on trying out macOS 27 as soon as possible, please ensure you install a secondary copy of macOS 26 first, or install macOS 27 itself on a secondary volume." They've also updated the installer to prevent installs from running on macOS 27 for now. For anyone who ignored all of the above, "we will not support users who have installed the macOS 27 beta without ensuring at least one stable version of macOS is installed." Considering macOS 27 is in beta, the issue may be accidental rather than an attempt by Apple to block Linux on its hardware. The Asahi team said it has filed bug report. The good news for anyone who pulled the trigger on installing the macOS 27 beta is that although the partition might not be visible, it hasn't gone anywhere. The Asahi team wrote: "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." Read more of this story at Slashdot.
