Has anyone done this yet? I have had a XT in my 2010 13" MBP for the last month, no issues at all. I'm giving my 2010 to my nephew and reinstalling the stock HD before I send it to him. When I install the XT in my 2011 should I do a fresh install? I dont have any files, ect that I really need to carry over. If I do a fresh install, should I use CCC to clone the HD in the 2011 then install the XT or just install the XT and put in the iOS disc? TIA!
