borckard posted a topic in The X-Plane General Discussions ForumI just bought a brand new iMac running OSX 10.9.1 with a fusion drive and x-plane 10. I have USB flight controls by CH Products (worked fine on X-Plane 9 with my old mac). I can calibrate the usb controllers and see that X-Plane reads the full range of motion continuously in the calibration screen without issue. As soon as I switch back to the simulator to fly, the usb flight controls seem to move the designated airplane control about half-way and then stick. At that point, they can no longer be moved at all by the usb controllers. Any help would be much appreciated.
