Hi, I know search....I'm am! But you guys are so good I thought I'd get the real answer by asking! My sister and I are going to swap our MBA.....mine is is 11" mid 2011 and hers is a 13" mid 2012. What is the easiest way to swap everything (data, software) between the two of them? I'm fairly comfortable with working on the MBA if I have good instructions. Can anyone help?
