In that case, try running the update for the T7 RAAS from the RAAS website.

Look for "click here to download".
I think it should work ok. I can use the T7 on my late 2013 macbook pro retina. It does have the GT 750M with 2GB GDDR5, however I only have a 2.3GHZ processor. With ASN, FSUIPC, EZCA, and some others, it runs pretty well. On a clean install with those 3 addons I have no issues maintaining 30fps.
It seems to be a problem with the USB 3.0 ports. My late 2013 Macbook pro retina has 2 USB 3.0 ports, no USB 2.0 ports. My other saitek products work fine, but I still haven't found a solution for this problem.
