So I either suck at searching or there isn't much info about it. I got this imac in 2007 with 10.4. When 10.5 came out my brother-in-law bought the family pack and I used it. He lives nowhere near me. My hard drive got erased. It was backed through time machine. However, when I restored my hard drive I used the 10.4 disks that came with the computer. Now, is there a way to restore my files that were backed up via time machine and get my computer back to being in leopard without having access to the leopard install disk?
