So I've read that it is possible to enable Virtualisation on MacPro 2008 however I do not find how.
I know that I have VMX since the output of
sysctl -a | grep machdep.cpu.features is :
machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT PSE36 CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM PBE SSE3 DTES64 MON DSCPL VMX EST TM2 SSSE3 CX16 TPR PDCM SSE4.1
But I think what I need to enable is the virtualisaiton support which I can check with :
sysctl kern.hv_support and output me
So how can I enable it ? I've tried to install the EFI update from this official link but it tell me than the update is "not necessary".
