Mouse acceleration is something most Mac users don’t think twice about; many aren’t familiar; it even prevails. They are not even aware of this term, thinking it is not essential. Many of them struggle with mouse behavior on Mac Operating Systems. But to first solve the mac mouse acceleration problem, we will need to know some basic things.

So, before we learn how to turn off mouse acceleration, let’s first figure out precisely to the problem.

What Exactly Is Mouse Acceleration?

A typical dictionary defines acceleration as the rate at which something moves more quickly or happens faster or sooner. Just like in a car, for example. Step on the gas pedal gradually, and the speed increases slowly. Step on the gas hard, and the car will speed up quicker.

Mouse acceleration is similar to that. It means that the quicker you move the actual mouse across the surface, the faster the mouse pointer moves on the computer screen. This is what allows regular computer work to be done more efficiently.

Because the distance traveled by the pointer is not dependent on how far you move the mouse; instead, it’s how fast you do it. If you need to go from one end of the screen to another, all you need is to flick the mouse quickly.

Mouse acceleration is actually a standard speed setting to decide the mouse’s speed when it is moved from one point to another on a screen. This is why, by default, mouse acceleration is turned on in most operating systems. When you’re using your computer and have limited space for your mouse, it works in your favor.

All you need to do is to move it fast. It is a space and energy saver. Not to mention, repetitive but straightforward tasks become more manageable.

Examples are surfing the net, moving single files from folder to folder, and using a photo or video editor for work.

Mouse acceleration can be a real headache while gaming. That’s because these games often rely on fine-tune adjustments. When mouse acceleration is turned on, it can seriously mess up any precision shots or necessary in-game adjustments.

Fortunately, turning it off in Mac is a straightforward process you can do in about a minute. If you want to move the mouse precisely between two points on the screen, you need to turn off acceleration.

Turning off Mac’s acceleration is a bit more tricky than in Windows, but if you use a Mac in your business or gaming, you can still turn off this setting. You can turn on acceleration later if you wish.

How To Turn off Mouse Acceleration In Mac

These three methods mentioned below by which one can turn off Mouse Acceleration in Mac

1st Method

Disable mouse acceleration with defaults.

  1. Press “Command-Space” to open Spotlight, type “Terminal” in the search box, and click “Terminal” to launch the utility.

All settings take effect only after you log out and back in or after you restart your Mac.

Undo Mouse Acceleration

Suppose you would like to revert back to the apple default settings of mouse tracking speed or mouse acceleration. Just open the Mouse pane of System Preference and change the Tracking Speed of Mouse.

2nd Method

Using a command-line script to stop mouse acceleration

From my research + trial and error, I have found these three terminal commands to be most successful in getting rid of mouse acceleration on a mac.

Enter in these three commands, after each one press Enter, then place in the next one.

  1. Curl -O
  2. Chmod +x killmouseaccel
  3. ./killmouseaccel mouse

After entering these three commands, your mouse accel is removed, and you should be able to play more consistently and competitively in gaming.

3rd Method

Manually adjust Mouse Acceleration with a Preference Panel.

If you want to adjust the mouse acceleration on Mac, you can download the Mouse Acceleration Preference Pane. This allows you to adjust the mouse acceleration through a preference setting because, by default, this isn’t readily available on Mac.

If you want to control the mouse’s acceleration precisely, you can drag the cursor to the left or right, depending on your preferences. Under the mouse acceleration preference setting, there’s a checkbox that says Enable Mouse acceleration at login. When you check this box, it allows the mac acceleration settings to command.
