The Asahi Linux team has issued a warning to users of Apple Silicon devices against upgrading to the macOS 27 beta due to significant changes in the boot picker and Startup Disk app. These modifications render Asahi partitions invisible, which prevents Linux from booting on affected devices. The team advised users to retain a stable version of macOS 26 or install macOS 27 on a secondary volume before making the upgrade. They have temporarily updated their installer to block installations on macOS 27 to prevent complications. Users who proceed with installing the beta without a stable version will not receive support from the Asahi team. Despite the visibility issue, the Asahi partition remains intact, and users need not worry about data loss.
Why It Matters
This issue highlights the ongoing compatibility challenges faced by alternative operating systems, such as Linux, on proprietary hardware like Apple’s devices. As Apple continues to evolve its macOS, changes to system architecture can inadvertently impact third-party software and operating systems. The Asahi Linux project aims to enable Linux on Apple Silicon, which is significant given the growing interest in open-source alternatives. Ensuring stability and compatibility is crucial for the success of such initiatives, especially as more users explore dual-booting options on their Apple devices.
