I have an old (4+ years) MacBook that’s on its last legs. I’m going to purchase a new one within the next year, but before I do so, I have some concerns. Obviously the new MacBook Pros are all running Mountain Lion, but my MacBook is still on Snow Leopard. If I choose to transfer my user account and all associated data using Migration Assistant, will anything be lost/incompatible?
Mine is the only account on my laptop, and I back up to an external drive with Time Machine regularly.
