The Asahi Linux team has warned users of Apple Silicon devices not to install the macOS 27 beta. Changes made by Apple to the boot picker and Startup Disk app render Asahi partitions invisible.
The team stated that these modifications prevent Linux from booting on affected systems. Users who have already upgraded face the risk of losing access to their Linux installations. The warning comes directly from the Asahi Linux developers, who advise against testing the beta if Asahi Linux is installed. They noted that the issue stems from Apple's updates to core boot management tools. If users insist on trying macOS 27, the team recommends proceeding with caution to avoid disrupting existing setups. No immediate fixes or workarounds were detailed in the announcement.
