9.2.1 . . . and it crashes and freezes relentlessly. I make sure it does, otherwise it isnt being pushed far enough. Got OS X to get iMovie 2, then left it to late to get Office 2001 so I need it to run Office X. Maybe if Poser 5 only came out in 9.2 it will be out at the same time, let the X version be late. My version of OS X is labled BUILD 5J34 whatever the hell that is.
