I'm looking to put the OS X10.5 on my old ibook G4 with 1Gb RAM that currently has 10.3.9 on it. I have the 10.5 upgrade disk from when I bought a new imac but i need 10.4 first. I don't know if its a good idea to get a pirated version of 10.4 or if there is a way around that road block, and I really don't have the money to buy a $100 upgrade disk for 10.4 to get 10.5 that I already have. Also I don't even know where to look to find a torrent for this or if it can be trusted, but this site looked promising to get me a good answer. So thanks for the help =D
