I was told that unlike Windows, Apple does not make a full install and upgrade version of the OS disc. They only make an "OEM" version of the disc that comes with your Apple. If for example you bought an iMac, the disc that comes with it, will only install on an iMac.
I have checked eBay though, and find listings for "Full Install" and "Upgrade."
I was recently given a PowerBook G4 with OS X 10.2 installed. I would like to do a fresh install of the OS (and possibly upgrade to 10.3 or 10.4 - depending on price), but I do not want to spend much money on it, as it is the very first PowerBook G4, and is very dated.
If there is no difference in the discs, then I see no reason to pay more for a full install, when I can play $10 since I already have the OS, and only need a disc.
Could the Apple guys clear this up for me?
