Uh, sick? Pro Engineer is available for Windows, UNIX, and LINUX... you are aware that OS X Leopard is one of the four fully certified UNIX™ operating systems, aren't you? If it runs on UNIX™, it will run on the Mac. If it runs on LINUX, it will run on the Mac. If it runs on Windows it will run on the Mac.
No, I'm fine, but thanks for the concern.
I don't see any mention of Mac on Pro/E's platform requirements document on PTC's website but maybe you can show me where I missed it: http://www.ptc.com/WCMS/files/52592/en/proewf4.pdf
Thanks in advance.
