Hi all, So I have that other thread regarding which, between a G4 iMac and G5 Powermac, I am going to possibly purchase, but I'm a little uneasy about the lack of OS discs. Googling and Craigslisting has a plethora of people who have discs for purchase, but isn't it kind of machine-specific? Where or how would I go about having a safe backup in the event I need/want to reinstall OSX.4? I looked on Apple's site as well and couldn't really find the answer... I realize as I'm getting closer to purchasing an older Mac for my theatre's playback system, not having the install discs if something happens makes me nervous! Thanks for your help!
