it's.....JAGUAR!!!! yup. I've had nothign but problems with Panther. I've done multiple clean installs after initializing and zeroing my HD. Tried it with archiving, saving my prefs, redoing them from scratch... no matter what there was always problems and my computer (Dual 1.25 G4 1st version w/ 2GB ram) FROZE AT LEAST ONCE A DAY. I now love jaguar even more than before, and everything is great since I finished getting everythign installed earlier this morning!!! I love a stable OS, just thought I'd share. and now I can go be productive without having to restart my computer or turn it off when it freezes, SWEET!!
