Just thought I'd let you guys know that the wrapper here http://www.paulthetall.com/tomb-raider-2013-mac.html works almost perfectly on my 3.4GHz i7, 16Gb, 6970M 1Gb iMac @ 2560x1440. Buy the game on Steam and enjoy! Incredible graphics, and very smooth frame rate. The only glitches are when reading documents and lack of icons in the load game dialogue. Neither of which are a big deal.
