Disable Mouse Acceleration in Mac Terminal (Sonoma/Vetura)

Summary: This article from iBoysoft explains what mouse acceleration on Mac is and how to disable mouse acceleration on macOS Sonoma, macOS Ventura, macOS Monterey, and earlier versions.

MacOS Mouse acceleration is a built-in feature that adjusts the distance the cursor moves on the screen based on the speed of the mouse. That said, the faster the mouse moves, the further the cursor travels.

This allows you to move across the screen without having to physically move the mouse a great distance, which is particularly helpful when using a touchpad or working in a confined area.

However, mouse acceleration can be troublesome for designers, developers, gamers, or users who prefer the cursor to move proportionally to the distance the mouse is moved. That's why we'll discuss how to turn off mouse acceleration on Mac in the following paragraphs.

What is macOS mouse acceleration?

Like Windows, mouse acceleration on macOS modifies the mouse's sensitivity according to the pace at which it's moved. This means that the cursor will move different distances for the same mouse movement, depending on the speed.

While some users enjoy this feature, others want to disable mouse acceleration on Mac to ensure a more predictable and consistent cursor movement.

Way 2: Disable mouse acceleration on Mac via Terminal

If you're running macOS Ventura or an earlier version, you can deactivate mouse acceleration on Mac in Terminal.

Open Finder, then launch Terminal from the Applications > Utilities folder.
Type in the appropriate command to disable mouse acceleration on Mac. (Replace mouse with trackpad if you're working with a trackpad.)
For macOS Big Sur and later:defaults write -g com.apple.mouse.scaling -integer -1For macOS Catalina and earlier:defaults write .GlobalPreferences com.apple.mouse.scaling -1or defaults write -g com.apple.mouse.scaling -1
Hit Enter to execute the command.
After the command is executed, log out and then log back in to activate the change.

If you want to turn mouse acceleration back on, type the same command that worked for you, but change the number value from -1 to anything from 0 to 3.

Way 3: Use a third-party app

Alternatively, you can pick a free third-party app to disable mouse acceleration on Mac. LinearMouse is a good choice, as it's open-source and allows you to turn off mouse acceleration or find a balance between pointer acceleration and mouse/trackpad speed. It also enables you to configure different settings for your mouse and trackpad.

How to reduce mouse acceleration on Mac?

Instead of deactivating mouse acceleration, you can also reduce mouse acceleration by adjusting the speed of your mouse or trackpad. The table below shows you how tracking speed translates into mouse acceleration.

Tracking speed (ticks)	com.apple.mouse.scaling value
0 (Slow)	0
1	0.125
2	0.5
3	0.6875
4	0.875
5	1
6	1.5
7	2
8	2.5
9 (Fast)	3

To reduce mouse/trackpad speed, follow the steps below:

Open System Settings/Preferences.
Search for "tracking speed."
Move the slider to customize the speed.
