You may want to email them directly, and chuck a post in Marketplace Support, with screenshots (No means to take screenies? Skitch is an awesome little app that works fine on MacOS to take screenshots with - it's free, in the App Store.)

This is likely something they either know about already, or will be finding out very quickly.

(I had to flop over to a Windows laptop awhile back because the MacBook Pros don't do nVidia anymore :( I'll check to see if Apple comes to their senses in that department in a year or so.)
