I tried using this for Mac with my Canon 6D today. What a pain in the but the program is to install to begin with and then I had connection problems.
Once I had the camera connected and the software all installed I went about getting the testing going. I tried 3 different lenses, 24-105 f4, 70-200 f2.8 ISII and Sigma 35 f1.4. I could not get a result with any of them and used multiple light sources for each lens.
I've sent them off a request for a refund as I don't think the Mac version has all the bugs ironed out yet.
