Comments on: Kill Mac OS X Mouse Acceleration from the command line

I’ve tried FOUR different apps to get rid of mouse acceleration on the mac and NONE of them “actually work”.

For example, with this one, it appears to remove acceleration if you’re strafing the mouse only to the left and right or only up and down, BUT if you strafe diagonally, it completely breaks. Just try it. wiggle the mouse at a 45 degree angle on the screen back and forth over a distance of 2 inches on the desk over and over, first do it slowly and then do it quickly. You’ll find that if you do it slowly, the mouse only covers a couple of pixels. If you do it quickly, you’ll find the mouse covers the entire screen!

The same thing is visible if you spin the mouse cursor in a circle instead of a straight line. So yes, proof that this app fails just like all the others.

The original source code was posted in http://forums3.armagetronad.net/viewtopic.php?p=196564#p196564. An Xcode project version can be downloaded from https://github.com/docwhat/killmouseaccel.

Note that the utility has to be run again every time after logging in. The changes are also undone if the tracking speed is changed in System Preferences. If you want to use a different tracking speed (the default speed was pretty slow), you have to change it in the source code.

Running the script results in a marked improvement for my use of the Magic Mouse, not so much so for my use of the Magic Trackpad. While the speed of the mouse remains high after the custom acceleration settings are negated, which suits my general preference, the trackpad speed ends up being pretty slow, which I don’t like. What is needed, of course, is the ability to independently adjust the acceleration as well as the speed over a range of values. I’ve been able to successfully use this feature of Steermouse for previous Apple mouse products (Magic Mouse isn’t currently supported by Steermouse), and I’ve used Mouse Acceleration with some some success, although the adjustment values for the mouse, which allow inverting adjustment between acceleration and speed, result in a mouse speed that’s so fast, I can only use its “-0.0″ setting for the mouse. The trackpad’s speed doesn’t appear to be very adjustable in the inverted mode. I’m planning to try USB Overdrive, although its name would seem to indicate that it might not be appropriate for mice and trackpads connected through Bluetooth.

This could be a incredibly bad thought by Overdrive. It sounds like we’ll have however yet another format for libraries to choose from. So what I see is that libraries will have less selection as it has to purchase ePub, audio, & now Kindle. So that is not going to be good overall for patrons. I for one do not want to see a book I want in Kindle only when there is an ePub version just because someone with a Kindle requested it that way. The way things work now is fine. They way they could work won’t be fine. Far from it. What this is going to do is possibly cut the amount of new eBooks at libraries in half.

I’ve recently upgraded to a gaming mouse in a venture into competitive TF2 and I’ve since disabled all mouse acceleration so this makes my Mac much nicer to use.

I use your method, but I don’t like the result. How to put the acceleration back? =)))
