M4 Macs Limited to macOS Ventura 13.4+ for VMs
New M4-based Macs are unable to run virtual machines of macOS versions earlier than Ventura 13.4, as reported by users and developers. This issue, highlighted by security researcher Csaba Fitzl, affects popular virtualization software and results in a black screen during VM boot. The problem, occurring during early kernel boot processes, is not present in M1, M2, and M3 Macs. A fix would require Apple to release updated IPSW files for older macOS versions, which is unlikely. Supported macOS versions for virtualization on M4 Macs include Ventura 13.4 and later.
