I have just bought a 2014 Macbook Air to replace my ageing 2009 iMac. I recently did a fresh install of Yosemite on the iMac so am 100% happy with the setup (apps etc) so do not want to have to set up the MBA from scratch. What's the best way to do it - can I restore my Time Machine backup on the the MBA? I assume it has different drivers etc from the iMac. Or should I just use Migration assistant? I have had mixed results with it in the past, especially with accounts and software licenses. what I want is a carbon copy of my iMac on the new MBA, not simply 'most of it'.
