Must be plenty of those, but maybe the combination of Mac and RAW files is less commonly covered? Not using Mac myself, so wouldn't know.
As I recall you're using a Transystem GPS logger and there is a dedicated program, GPS Photo Tagger, for it which can show not only GPS track logs, but also photos on a map and likely allows writing GPS info into photos. It accompanies the Transystem itself so you ought to have it already. It might need jpgs however, so if you only shoot NEFs no luck unless you alter your routine to include RAW + jpg. Don't know whether it runs under Mac, though.
I don't understand why Nikon had to abandon the use of map view in NX Studio, as there are lots of APIs that can link GPS data [from photos] to map views and don't depend on IE. They aren't locked in to Google Maps either as there are open-source maps and APIs out there in the plenty.
