Hello everyone, my sister recently gave me her old imac. However, she only had the second recovery disc and, as fate would have it, I need to restore it, thus, I was thinking of buying the discs off of ebay. However, I wanted to ask a question first. The only discs I can fond are for 10.5, however, mein runs off of 10.4. Does that make a difference? I assume it would not, but I just want to make sure Thank you for your time.
