How to Roll Back After an Unsupported macOS 27 Beta
If an Intel Mac will not boot after an unsupported beta, focus on recovery and data preservation rather than forcing the same installer again.
Step-by-Step Rollback:
- Stop reboot loops: Power off fully and disconnect external accessories.
- Boot Option menu: Hold Option and choose your previous OpenCore/macOS disk if available.
- Use recovery installer: Boot a supported macOS USB such as Sequoia or Sonoma.
- Reinstall over the system: Try reinstalling without erasing first to preserve data.
- Restore backup: If the system volume is damaged, erase and restore from Time Machine.
