I am running KSP .0.90.0.705 (Steam) on my mac running 10.6.8. I am having joystick problems as well. I have played KSP for over a year using a Microsoft SideWinder Precision 2 with no trouble. In the past month I have had lots of problems getting KSP to recognize it during game play. Then two days ago it gave up the ghost. I could not get any functions to work and I could not reassign any functions. So I assumed that the stick was dead. I purchased a Logitech Extreme 3D Pro today. Still no go. No buttons nor axis were seen by KSP in the assignment attempt. I purchased a test program and both my joysticks and all buttons show up in the test software. I went back to KSP and continued to try to assigning functions to my new Logitech. Nothing. Then with my Logitech still plugged in, I plugged in my SideWinder. Now KSP would see button presses of the SideWinder. I tried the Logitech, and now KSP can assign those buttons as well. But the axises of both sticks are still not seen. I cannot get KSP to see any axis of either stick. Pitch, Yaw, Roll, Throttle, and strangely, the hat buttons of both sticks cannot be assigned in KSP. I still have some of the Sidewinder axises assigned from before, but it is not seen during game-play, and non functional. But if I clear the assignment, I have no way to get it back as the stick axises are no longer seen in KSP. And I have tried every version of re-boot and restart the game I can think of. I even removed all my mods (hence me posting here). Nothing I have tried will allow either stick's axises to be seen by KSP anymore. I have 401 hours playing this game and this issue has never come up for me until recently. It could have crept in in the last update. I have not been able to play much since then and I am just trying to get back to it.
