Panther is probably the highest version of OS X that will comfortably run on this machine.
If there is nothing on the iMac G3 that you really care about, the best thing to do would be to do an Erase and Install. This formats the drive, removes the partitions and deletes all your existing data. This is by far the best way to go. The HD on this machine is a little small but it's not a show stopper.
You said "cause I know its not that simple" and I say "Oh but it is!"
That is all that is involved with moving up to Panther on that machine. Insert CD, click Install OS X, reboot, choose Erase(format) and Install then sit back and enjoy the ride. If you want to save your data, it is nearly as easy. You just do an Upgrade, Archive and Install. All your data is saved and put back where it was after the upgrade.
So, which one?? Decisions, Decisions. ![]()

Ok, I have another iMac G3. Thanks to MrMacFixit, I got the other one back up and going. But this iMac G3 is a 400mHz, 512 mb Ram, 20 gb HD. It has OS9 on it and Jaguar on another partition. I really don't care for Jaguar and would like to upgrade this one to Panther. I know its hard to find Panther since Tiger is all the rage, but I know I could find it. Actually, Tiger would be fun to run on it, but this iMac, unlike my other, does not have a DVD drive. So, how can I upgrade this iMac? Do I need to do anything other than popping the Panther CD, cause I know its not that simple? Thanks in advanced. ![]()
