Poser 6 on the Mac is very poor. Poser makes very little use of the advanced OSX and PPC features. Poser 6 is still locked into an old version of Python so advanced scripts have problems. The Mac is also a second class citizen in the poser community, especially when it comes to third party support. While I have found that the Mac is a better computer in many many respects. You will have problems with whatever platform you choose, they will just be different sorts of problems. Select your poison. Estruch: If you are having kernel panics then there's something wrong with your Mac. This is not normal.
