Would a drive from a 2010 Mac Pro with 10.8.2 or even 10.8.3 boot the new imac? (TB enclosure) or would I have to use the installed image and clone it and Time Machine restore? I wonder if 10.8.3 has all the files/drivers inside required for the new imac? When you use an image from another Mac product on a different mac model in the past, what happens?
