Add an uninstaller on the cd for all native instruments products for Mac. I have TSP, TS4, and Maschine. it's a pain to try and filter through the files and remove the "saved settings" from Mac. Even with the knowledge base info, it took me 3 tries before I got all the files related to TS4 removed and reinstalled. In the end, I had to remove all NI programs and reinstall because it was easier than trying to filter through.
