Uh, Poser was written for the Apple (don't know which one) NOT the Mac. Sorry, but actually Poser was written for the "Mac". The "Macintosh" first appeared in 1984 and every Apple computer since then has been a "Mac". There were a few questionable naming variations along the way, like the "Performa" but overall every Apple computer since 1984 has been a "Mac". I still have the original 3 disk instal of Poser 1. It's a pretty funny thing to see! ; )
