Hi, I have recently just purchased this beautiful iMac G5 from 2004 off of ebay. The computer was barely used, and in mint condition. Anyway, it had 10.3.5 panther installed on it, and I need to upgrade it to 10.5 leopard so that I can get all of the files off of my old pc. Well, I bought a copy of 10.5 off of ebay also (last week), and when I tried to install the new software, about half way through it keeps giving me countless error messages! I called apple 3 times to see if they could help, but, to no avail. I've looked on the net, and still no help. I tried to "Reinstall" the 10.3.5 on my computer, but, that is starting to give me error messages also, and won't install all the way through back into the computer. I don't know what else to do? Obviously, I have "supposively" damaged the hardware some how I assume, but, just a week ago the pc was working fantastic. Just to let all of you know I am first time mac user, and really don't know much about upgrading, and all that jazz (Not that it seems too difficult either). I just popped in the cd, and started to install, but, I never downloaded or put anything into the mac since I first purchased it 2 months ago because I was planning on upgrading. This is really holding me back, because I need this computer to have this software on it so that I can install the latest printer I have (For my college homework) as well as to store all of my music on. Just to add in (I also recently upgraded to 2gb of ram). Now, I don't know what else to do?
