Mouse acceleration Mac has integrated into its operations is a feature that has long been a part of what makes our Mac experience seem so effortless. The beauty of it is that most users don’t even know it exists. At the same time others look for ways to disable it so that they can achieve top results in what they do.
Usually we don’t give much thought to how the cursor follows the movements of the mouse and tend to assume that their connection is literal: you move the mouse — your cursor follows with the same distance on the screen. What we don’t always realize is that the cursor adapts its movements to the speed at which the mouse is moved.
This way mouse acceleration spares us the need to move the mouse back and forth multiple times to get from point A to point B. But at the same time it also results in inconsistent mouse sensitivity. Thus, it’s useful to learn how to turn off mouse acceleration on Mac should your activity call for pixel-perfect precision of every move.
What is mouse acceleration?
Mouse acceleration Mac offers as its built-in feature, speeds up your mouse-to-cursor response. Normally the distance your cursor covers on the screen is in the natural 1:1 proportion to your mouse movement. But after a certain speed (a fast swipe) or a certain boundary (as the mouse is moved over a particular point), mouse acceleration kicks in, and your cursor gets further faster.
The main idea behind the feature is to increase mouse reach and functionality, especially so that it doesn’t require much space to operate efficiently. If you remove mouse acceleration Mac features, your cursor will go back to naturally mirroring mouse movements.
Good reasons to turn off mouse acceleration on Mac
Most of the time we don’t even notice mouse acceleration at work. However, there are instances when cursor precision is critical for the task at hand and we’d rather have macOS disable mouse acceleration.
The two most popular reasons you might want mouse acceleration turned off for are design and gaming:
- Drawing precision. If you design on Mac and prefer to work without a stylus, mouse acceleration will have a considerable effect on how accurate you can be. To gain more control over your cursor movements you’ll definitely want to learn how to turn off mouse acceleration on Mac.
- Gaming performance. Mouse acceleration can quickly become a problem for your shooting aim, preventing you from attaining high scores and messing up with your muscle memory reflexes. If you disable mouse acceleration Mac will let your cursor move solely based on the physical movements of your mouse, and you’ll have a better control over your aim.
Another reason you might want to remove mouse acceleration Mac offers is a stronger general sense of control some people feel when the cursor moves with the same speed as their mouse.
How to turn off mouse acceleration on Mac using Terminal
To remove mouse acceleration Mac users need to use a Terminal command. It allows you to switch the feature off until the next time your Mac restarts.

- Open Terminal from the Finder menu: Applications ➙ Utilities ➙ Terminal
- Type defaults write .GlobalPreferences com.apple.mouse.scaling -1 into the Terminal window ➙ Enter
- Close Terminal
Tip: You can use the same Terminal command, changing the -1 value at the end to any number from 0 to 3, if you decide to turn mouse acceleration Mac default back on.
