is there some way to roll back a major update like a secruity update? im thinking it is the cause of some pretty annoying bugs since it started when i got it. running aluminium C2D iMac 2.0 ghz. 10.4.11 for the last 2 days things have just been crashing randomly. msn, firefox, itunes, you name it. this has never happened before. im just scared it will happen to something more important like final cut and ill loose all my work. *edit* just happened again. lost firefox and all my tabs. didnt even restore them when i loaded it back up like it wouldve noramally done. this is pretty irratating.
