I am not sure - it depends on whether the processor in the 6,1 can run VMWare Fusion 13. Fusion 12.1+ does not work on the cMP5,1 (outside of Catalina) due to unsupported CPU features as Fusion 12.1+ uses Apple's hypervisor not a kext.Can Mac Pro 6,1 trash can running macOS Monterey run Windows 11 Pro using vmWare Fusion 13?
Fusion 13 has the virtual TPM module. I'm using it to run Win 11, though I'm using it on ARM. You need the workaround yet?Fusion 13 works just fine with windows 11 on the 6,1. I'm running it right now. You have to use the TPM and secure boot workaround since there is no TPM module but the CPU IS supported. (insert more eye rolls)
