Hi, I will purchase the new MacBook whenever it is going to be released. I already have a mac pro and was wondering how I would be able to sync the two macs ENTIRE hard drives??? Not just calenders, mail accounts and other mobile me stuff; the actual ENTIRE HD. Is there an app out there or anything that can sync all data between 2 or more computers? An app that does not just treat my Mac Pro as master but also detects that my MacBook may have information that my Mac Pro does not have yet? So basically like Mac to Iphone sharing? When you purchase a song with the iPhone it syncs it back to your back, or when you add a contact it syncs it back to your mac!? Thanks for the help!
