I'm running X-Plane11 on an iMac (High Sierra) via Steam. I've just bought a Cirrus SR22T (yaay!) and have installed the Carenado SR22_GTSX_Turbo plugin to add that aircraft. When I start X-Plane, I do see the Garmin glass panels, and a prompt to enter the Carenado serial number. I hit NEXT, but nothing happens.
Carenado support suggests removing all plugins. I don't know how to do that. Any advice on either issue would be greatly appreciated!
