I'm getting a new MacBook Pro and am planning on selling my iMac G5. My question concerns restoring the machine for sale. I want to get rid of all my files and programs and such that I've added over the years, but the problem is I want to keep the OS up-to-date. I think I purchased it with 10.3 installed, and now have 10.5.5 on there. I don't want to use the restore disk and risk reverting it back another 2 generations. Any advice? Thanks for the replies guys. Problem is, I don't have the 10.5 disc (used a friend's family pack). Is there any way I can find it online or something? Maybe bring it into the store?
