Hi, I'm hoping someone can point me in the right direction. I'm about to buy a iMac and a MacBook, and what I want to be able to do is have each computer mirror each other. So when I go see a client with my MacBook and make some changes to some files (photoshop, illustrator etc) that when I get home the computers will update each other, so I never loss files and if one crashes (power cut etc) I can keep working on the other. The people at the Mac store said I couldn't, I find this hard to believe. So if you know of a bit of software out there that can help me please let me know, as I want to set this up correct form day one.
