Just purchased a new MacBook Pro yesterday. So far, everything seems to be going pretty great with the machine itself. Love it when I get the chance to use it (been swamped with work today & will be tomorrow so the opportunity to play with it has been minimal). But yesterday when opening up my new toy and trying to migrate the data off my old Air, I did have a bit of difficulty. I do my Time Machine backup to an external SSD inside this enclosure. I've been using it with my Air for the past six months and it's been pretty great so far. For restoring the backup to my new Pro, I bought this cable to get the data off the drive (Benson Leung approved). Problem was the the drive wasn't recognized by the Pro when I plugged it in with the new cable (still works fine on the Air with the included USB 3 cable). Oddly enough, the new Pro recognized my old Air thought that new cable when I plugged it in through Migration Assistant and it moved my data (albeit slowly) to my Pro. I can't determine why this is the case. Any thoughts? Maybe a different cable?
