So, I think we can agree that (forfor non-Server versions):
- OS X 10.6 and below: It is not allowed to ask about its virtualization
OS X 10.6 and below: It is not allowed to ask about its virtualization, as this equals running "Hackintosh" modifications, which we have never allowed.
- OS X 10.7: It is allowed to ask about its virtualization
OS X 10.7: It is allowed to ask about its virtualization, but only within Mac OS X running on an Apple computer.
The pure reason being that Apple will obviously specifically allowspecifically allows it for 10.7:
(iii) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple SoftwareApple Software.
… and the fact that, for example, Parallels 7 finally specifically allows the virtualization of OS X 10.7, but not any other OS X version.
