Basically, rather than re-build my computer from scratch (re-install all my apps etc) I would like to clone my current hard disk to a Retina disk. My idea is to put my SSD from my Macbook Pro into a thunderbolt case, boot the retina up on this and then clone my disk to the Retina's disk using SuperDuper. That's the theory but I can't seem to get past first base of booking the Retina up from the Thunderbolt port (using the SSD from my classic Macbook Pro (running 10.9.2)). It starts to boot but then get stuck on the swirling wait icon thing. Anyone any thoughts?
