M4 Macs Incompatible with Older macOS Virtual Machines
Apple's new M4 Macs face issues running virtual machines on macOS versions prior to Ventura 13.4.
- Users attempting to run older macOS versions on M4 Macs encounter a black screen and failed boot.
- The issue arises during the early kernel boot process, affecting all major virtualization software.
- M1, M2, and M3 Macs do not face this problem and can run older macOS versions in virtual machines.
- Developers and users relying on older macOS for testing should consider this limitation before upgrading.
- A fix would require Apple to release updated IPSW files for older macOS versions, which is unlikely.
