Hi. I have just bought a new iMac from apple store and am using migration assistant to transfer all information from my MacBook Air which I use as a portable so I will be using both macs. But I started doing the transfer weds 6pm using my wifi and it has taken 72 hours so far! I am going away tomorrow and need to take the mac air with me so am worried that it will not be finished and that it is not doing what it is meant to be. Plus I can't use either while transfer is happening and am up against deadline. Help! Many thanks. Liz.
