We’ve had several compatibility issues for 10.10 during the implementation of Joystick Doctor.
The good news is that if it turns out to be a common request, then we’ll implement the backward compatibility of the app in a future version update. Make sure you let us know by contacting us.
Even if you're using Yosemite or below we’d still suggest you to check out
Joystic Doctor Troubleshooting Site and let us know about your feedback.
