Hello, I got a Macbook air for work. I loaded backup from my imac via time machine onto this macbook air so both computers have exact same files. When I goto work with macbook air, the content for air would be newer than imac. I am wondering whether there is a way for air to sync with imac so that both computers are at the newest status without me needing to backup air with time machine, then load the latest version backup to imac. If so it would be very helpful as keeping 2 or more computers at the same status is a very difficult task. Thanks!
