I bought a used iMac G3 without the disks. I have a couple of problems, please help. I don't have the system admin name and password. I can't get on line w/ out it. 1. I'll email the guy I got it from maybe he knows. 2. If not. Do I have to buy OS X and start over. That's not a big deal, but the computer has tons of software on it. Is there a way I can 'save' the software and re-install OS X. 3. Or should I just sell it. I really need it to do some editing and I need an updated of Quicktime, which I think I can only get on line. What do you guys recommend? Thanks.
