Anybody know anything about Mac OS 10.3.9? My PowerBook G4 seems to get incredibly slow and unresponsive after using it for a while, and I need to restart it, and it will go back to normal... i was assuming that it probably needs a reformat, but maybe there is something a little less drastic that I can do that would help?
