I am new to the Mac. Period. My husband bought the PowerMac G4 (QuickSilver) 2001 and he abandoned it after 6 months. He only uses it to update his ipod, but lately he's been using his PC for that too. The Machine looks great, so one day (2 months ago) I decided to try to learn more about it. I read up on formatting the hard drive and reinstalling the OS (I recently bought and upgraded to panther). First, I loaded OS 9, then OS X 10.1, then finally OS X 10.3. I think I might have done something wrong because now applications that I loaded before, like mac office vx and Final Cut Pro 3.0, won't install. When I insert the CD, it just ejects. If there is anyone who could tell me exactly how I should have loaded the OS, I would appreciate it.
