having this same issue - latest osx build - calibration is just awful. seems to assign the yaw incorrectly and so some sticks work, others don't. my current models worked perfectly. seems to be an issue just on OSX
Edit: Clicking the circles is the only way to get this working on a new macbook. Was using a model that previously worked connecting to a windows install.
Note: one issue I am still having is that FPV freerider takes a moment to detect the sticks are centered instead having them all at min range. So you can get it working in calbration by just wiggling the sticks - they will center out. You must do this during calibration and before each takeoff in the sim.
