Hi, I bought a new MacBook Air last week. i turned it on 2 days ago and followed the Mac Migration process (over wi-fi) between my old and new MacBook Air. After 24 hours, the screen said 'About one minute remaining' however 12 hours later it was still saying the same thing. I went out and bought a Thunderbolt cancelled the Mac Migration. I've now just tried running it all again but it says there is not enough room on the new MBA. I've also just tried logging in as normal and none of the files are there on the new MBA. How do i wipe or clear my new MBA so that i can start the process again via the Thunderbolt cable? Thanks in advance for any help you have.
