Disabling Mouse Acceleration on Mac

Mouse acceleration is a feature that increases the speed of your mouse cursor based on the speed of your mouse movement. While this feature can be beneficial for some users, others may find it frustrating and prefer a linear mouse movement. In this guide, we will walk you through the steps to disable mouse acceleration on your Mac.

Understanding Mouse Acceleration

Before we delve into the process of disabling mouse acceleration, it's essential to understand what it is and how it affects your Mac's performance. Mouse acceleration is designed to help users have more control over their cursor. It works by increasing the cursor speed when you move your mouse quickly and decreasing it when you move your mouse slowly.

While this feature can be useful for those who use trackpads or are working on small screens, it can be a hindrance for others, especially gamers who require consistent cursor movement. Disabling mouse acceleration can provide a more predictable and linear mouse movement, leading to improved accuracy and performance.

How to Disable Mouse Acceleration on Mac

Now that we have a clear understanding of mouse acceleration, let's move on to the steps to disable it on your Mac. Please note that these steps are intended for macOS, and the process may vary slightly depending on your operating system version.

Using Terminal

The Terminal is a powerful tool that allows you to control your Mac using command lines. You can use it to disable mouse acceleration by following these steps:

  1. Open Terminal from the Utilities folder in your Applications.
  2. Type the following command and press Enter: defaults write .GlobalPreferences -1
  3. Restart your Mac to apply the changes.

Remember, Terminal commands can significantly impact your system, so always double-check your commands before pressing Enter.

Using Third-Party Applications

If you're not comfortable using Terminal, there are several third-party applications available that can help you disable mouse acceleration. Some of the most popular ones include SmoothMouse and SteerMouse. These applications provide a user-friendly interface that allows you to adjust your mouse settings with ease.

  1. Download and install your chosen application.
  2. Open the application and navigate to the mouse settings.
  3. Look for the acceleration setting and disable it.

Keep in mind that while these applications can make the process easier, they may also come with additional features that you might not need. Always read the application description and reviews before downloading.

Adjusting Mouse Sensitivity

Disabling mouse acceleration can make your cursor movement feel slow, especially if you're used to the acceleration. In this case, you might want to adjust your mouse sensitivity. You can do this from the Mouse section in your System Preferences. Here's how:

  1. Open System Preferences and click on Mouse.
  2. Use the Tracking slider to adjust your mouse speed.

Remember, finding the perfect mouse sensitivity can take some time and experimentation. Start with a lower sensitivity and gradually increase it until you find a setting that feels comfortable.


Mouse acceleration can be a useful feature for some, but a nuisance for others. Whether you're a gamer looking for more consistent cursor movement or a Mac user seeking to improve your overall system control, disabling mouse acceleration can be a game-changer. Remember, you can always enable it again if you find that you prefer the original settings.

With the steps provided in this guide, you should be able to disable mouse acceleration on your Mac with ease. Whether you choose to use Terminal or a third-party application, the process is relatively straightforward. And remember, you can always adjust your mouse sensitivity to find the perfect balance for your needs.
