I transferred my virtual machines from one Mac host to another now none of them will power-up.
Was previously running Fusion 8, now I am on Fusion Pro 12.1
Error message is Failed to power on 'Path/vmname.vmx'
All suggestions welcome
I suspect you're on an M1 mac. That's not supported yet. There's a number of threads about it, but the net is that ARM guest support looks like it's coming. Intel guest support is unlikely unless there's a real surprise.
