My friend just bought a new Santa Rosa based MacBook with the 2.2ghz C2D. I have a white MacBook which I just bought in September, but it's non-Santa Rosa. His came with Leopard, mine didn't. So he burned me a copy of Leopard, which to my dismay, doesn't work on my computer. I get a "Software cannot be installed on this computer" error. I'm not sure why. I have searched Google high and low, I have tried searching several forums, and I can't seem to find why this is happening. I tried following the "unsupported Macs" how-to, but when I got to the point about editing the "Distrubution" file, there was nothing in that file. So I figured I'd ask here just to see if: A.) Anyone can explain to me why the Leopard discs won't work on my MacBook. Is there a difference in Santa Rosa discs and regular discs? B.) Has anyone else had this issue and is there a way around it? Sorry if this is in the wrong forum or if it has been asked before, but I'm at my wits end with this stupid mess and really just want to know WHY more than anything. Thanks!
