Hi all, I have a friend who owns a late 2006 17 inch 1.83GHz (C2D) with 512MB RAM. I was thinking about giving him the upgrade to SL for his birthday (he's running 10.5.8 if I remember correctly). I would give him the full version of course, just in case. But will it work? Or would I be better off just giving him RAM sticks? If so, what DDR2 RAM does that iMac use, and how much can it take? Thanks in advance!
