Mouse acceleration moves your mouse quicker than it might normally move to help speed up workflow. However, it can also be harder to control the mouse with this feature on, especially if you need to move precisely between two points, like when designing or gaming. Read on to learn how to disable the feature.
Using Command Lines
One method is to use command lines. Open Spotlight, which you can do by hitting the command and space bar keys at the same time. Type terminal into the Spotlight to load it.
There are three command lines to try, but be aware that command lines cannot be wrong and can cause issues if put in wrong. Changes can also be permanent. The three command lines to try are:
Curl-O http://ktwit.net/code/killmouseaccel
./killmouseaccel mouse
Chmod+x+killmouseaccel
You’ll then need to restart your computer. Now the mouse acceleration should be disabled.
Adjusting with Official Settings
You can also change how fast your mouse moves in official settings, which is much safer for the machine.
Click on the Apple menu.
Select System Preferences.
Click on the Mouse icon.
Adjusting the Tracking speed icon can change how fast the mouse moves. Turn it down to slow.
As you can see above, you can also adjust how fast double-click and scrolling work, too.
