Then move the mouse rapidly to right, but make sure the cursor doesn't touch the right edge of the screen. To test mouse acceleration, move your mouse so that the mouse cursor touches the left side of the screen and at the same time the mouse is touching an object (keyboard for example) on your desktop.
#MOUSELESS STEAM GAMES MAC#
Hopefully Apple will hear the cries of Mac gamers now that Steam is here. But even with the tracking speed turned down, there's a little acceleration. All you can do is to turn the tracking speed (or whatever it is called in english) all the way down under mouse settings and then use another application to make the cursor move faster.

Unfortunately there's no way to completely turn off mouse acceleration in Mac. Here's a pair of terminal commands (one for the mouse and the other for the trackpad) that disables mouse acceleration:ĭefaults write. It doesn't annoy me that much at the moment, but it does make looking around in an FPS way less controllable than on Windows. Now if Steam (more precisely the games themselves) just did something similar, I'm sure it could somehow get more "raw" mouse data. There should be a solution to this, as I have a graphics tablet that can easily change the way the cursor works with the help of a driver. So I'm guessing that the data the any application in OS X can access is the already accelerated mouse pointer data, not the actual movement of your mouse or trackpad. However, in OS X, there is absolutely no way to control your mouse, except how fast it moves. I believe there was an easy way for games to temporarily disable that as well. Yes in Windows you could uncheck "enhance pointer precision" in the Control Panel and you would get rid of acceleration.
