Disable mouse acceleration

Solution 1:

As far as I know, there is no way to do this without external tools.

Usb Overdrive lets you do this http://www.usboverdrive.com/ and is what I use.

Steer mouse also has this setting. http://plentycom.jp/en/steermouse/

Mouse Curves http://triq.net/articles/mouse-acceleration-preference-pane-mac-os-x Has the advantage of being free, but Apple removing the acceleration API in 10.6 may have ramifications on its utility.

Solution 2:

Go into System Preferences for Trackpad and turn the tracking speed all the way down to slow. What you can't do, I'm afraid, is have the mouse be unaccelerated and also reasonably fast.

Solution 3:

i like use Acc ExactMouse Pro For Mac http://www.zarell.com/product/acc_exactmouse_pro/

it also can disable mouse acceleration with assign application

Edit: it's available for free at the bottom of this page.

Solution 4:

I'm currently using SmoothMouse.

According to this forum post it should also reduce lag for pointer movement.

Fact: the on-screen pointer lags behind the mouse (or trackpad) in OS X more than in other operating systems, such as Windows or Ubuntu Linux.

To sum up:

• The problem has been confirmed by an Apple engineer (thanks to him for that) in an email correspondence with me. He has also mentioned that they were working on a solution.
• The problem has existed at least since OS X 10.4 "Tiger". The current version of OS X (10.8 "Mountain Lion") still exhibits the problem.
• Many people confuse lag with acceleration, this is what my blog post was about.

Solutions:

• SmoothMouse.
• Running Mac as a Synergy client with a mouse connected to another computer running Synergy server.
• Using Wacom tablet instead of a mouse.
