Somewhat OT so would you mind mailing me directly (unless of interest here) I’ve tried a few times to install a VM on my iMac 27. I dont recall detail but every install failed with VirtualBox *except* the hacked snow leopard install that I can install on any hardware … Snow_Leopard_Client_Server_10.6.2_SSE2_SSE3_Intel_AMD_by_Hazard.iso So … what did you do and how?
