I have an iMac G5 (look at sig for more details) Ok, I decided to switch back to panther because it isn't as much of a hog as tiger and I wanted to see how my iMac would run Panther. I completely erased the hard drive, and have (this was from the original seller, but the panther disks are mine): I have Jaguar 10.2 discs, a Tiger UPGRADE DVD, and OSX Panther. I stick the Panther disk in, hold the C button, but then it freezes on the apple symbol, the fans kick up, and nothing happens. I stick the Jaguar disk in, hold the C button, it just gives me a sign pretty much telling me their is no OS. I put in the Tiger DVD, and ran disk startup, and had an external dvd drive with panther in it, so I tell the Mac to restart under the Panther disk: It freezes just as I mentioned before, no difference. I put all my files on a dvd before I erased it, but now I can't get any OS to run on this iMac!! Please help!!
