So I got my first Imac. Am using Migration Assistant to transfer data from PC to Imac, machines hooked up via ethernet. But it keeps losing connection and I keep going back to square one. This has been going on for 5 hours - it gets about an hour into the migration, loses connection and I have to cancel and start again. I have followed all the instructions to the letter. I thought Apple was supposed to just work but this is a piece of crap. Is there a trick to this I am missing?
