Hello all Probably a simple fix (newb question) - but just got a Thunderbolt display - and new macbook pro retina 15". The 2-in 1 (thunderbolt/mag) cable that comes w/ the Thunderbolt display will not fit into the macbook pro, it's too large. I can see it's obviously a different Mag size - as my MBP charger is smaller. What do I do? Thanks!
