Hi all, I have 3 Mac computers running Lion. A Mac mini, a MacBook Pro and a MacBook. On each, I have two user accounts. One for me and one for my girlfriend. As we often swap the machines we need, I would like my (and hers) desktop background, dock, safari settings, etc... as well as the installed apps (some from the App Store, some dowloaded off the net) to be the same (and if possible, in sync) without manually configuring/installing apps on all 3 of them. Is this doable? If yes, how would I go about? Thanks!
