Here is my Dilemma, I got a Macbook Pro Unibody and just picked up a 2.4ghz Macbook pro 2008. I just Carbon Copied everything so that both machines are identical. My question now is How do I keep them in 'sync' ? Im a DJ and want to be able use both machines but keep them updated at same time. So if I buy music on on machine, and delete music on one computer I know I will have it on both. Pretty much a Carbon Copy of both at same time. Is this Possible?
