I have not heard of ProE running on a Mac while Windows OS is running. But I do know that UG is being ported to MAC, I do not know if it using Mac's OS X or Windows. I will ask some of my UG friends. - UPDATE, UG runs on MAC hardware but must use the Windows OS. Pro/e will have to follow the market or they will lose more opportunity for sales. the question is when and how soon. I prefer a MAC to Window, less problems, less virus attacks, MORE STABLE, It is easier to install and uninstall software. Hold value a lot longer. I could go on....
