Migration Assistant won't finish
I'm trying to use Migration Assistant to transfer files from my old Macbook Pro to my new one (15.4' MBP Retina running Yosemite 10.10.1) and Migration Assistant is hanging with 'about a minute left'. I'm migrating about 650GB from a TimeMachine backup. I left it running over night but it never finished.
What can I try to get this thing to work?
Thanks
MacBook Pro with Retina display, OS X Yosemite (10.10.1)
