When I got my current iMac (2010 model) I connected a firewire cable to my old 2006 model and the migration assistant transferred all my stuff. I'm getting a 2012 model, and was trying to figure out how to do the transfer. The 2010 model doesn't have Thunderbolt, so a thunderbolt cable is out of the question. The 2012 model doesn't have Firewire, so a firewire cable is out of the question. USB cable? Over the network (slow)? Or Plug in my Time Machine backup drive to the new iMac and restore from it?
