HI, I'm trying to upgrade a g3 (last tower model before g4's were introduced...I don't know the speed but assume it's 4-500mhz- it's my sisters), and it won't accept an os 9.2 disk to upgrade from os 8.6. We thought that since it wouldn't accept the panther disk that the computer needed os 9 before the X upgrade, but since this didn't work it's left me baffled. It's been suggested that we need os 9.0 before 9.2, and then you can step to OSX. Is this true? What's the easiest and cheapest way to make this transition? Thanks in advance.
