Not true. http://kb.vmware.com/selfservice/microsites/search.do?langua...
Actually, it is: > The grant set forth in Section 2B(iii) above does not permit you to use the virtualized copies or instances of the Apple Software in connection with service bureau, time-sharing, terminal sharing or other similar types of services. http://images.apple.com/legal/sla/docs/OSX109.pdf
"If you obtained a license for the Apple Software from the Mac App Store, (...) you are granted a (...) license (...) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments (...)".
So "No OSX version allows for virtualizing it as a guest VM" looks like an incorrect statement to me. Instead, some OSX versions DO seem to allow for virtualizing as a guest VM, under some conditions.
