The Asahi Linux project released version 7.1 with fixes for compatibility issues introduced by Apple's macOS 27 Golden Gate developer beta. Users reported that Linux boot options disappeared from the boot picker and Startup Disk after upgrading, though no data loss occurred. The team traced the problem to Apple's boot tooling now requiring a specific APFS metadata flag to recognize bootable volumes.

Apple's macOS 27 also brought firmware updates to the System Management Controller that broke battery monitoring. The SMC changed a battery management interface from returning 32-bit integers to single bytes, causing the Linux power supply driver to incorrectly trigger emergency shutdowns. This has been patched in the downstream kernel starting with version 7.0.12.

M3 machine support has improved significantly, with working CPU frequency switching, proper big.LITTLE task scheduling, and high-quality audio output now available. Since Apple hasn't changed core hardware interfaces like the I2S controller or Numerically Controlled Oscillator since M1, adding support required mostly Devicetree configurations. PCIe, Wi-Fi, Bluetooth, and other drivers are also functional on M3 series machines.

The report serves as a reminder that developer betas can introduce breaking changes, especially with global firmware updates that require DFU restores to rollback. Users are advised against installing betas on production hardware, though the Asahi team maintains sacrificial machines for testing these changes.
