I'm heling out a disabled person who's using an inexpensive Thrustmaster USB analog joystick as a mouse on a Mac running Yosemite. The speed of mouse movement is proportional to the distance the stick is from center. He says he is not using any third-party software to have the joystick act as a mouse. I was surprised by this. I don't have a Mac, but I know that on Windows you need a third-party program, such as joy2mouse, to have the joystick function as a mouse. He said he used to use joy2mouse but no longer does so. Is it true that an analog joystick will simply operate as a mouse on MacOS? Is it automatic or is it some option in the assistive technology settings? If not, do you have some idea of some other third-party software besides joy2mouse that would support this? He may have forgotten something that was installed to help him. The user is also using KeyStrokes, a third-party predictive on-screen keyboard. However, I don't see anything about joystick support in the doc for that program. Thanks.
