Increase Your Apple Magic Mouse Speed

Increasing the magic mouse speed is incredibly simple using just a few Terminal commands. Here is exactly what you need to do:

1. Open Terminal (Applications > Utilities > Terminal)
2. Type this command to see your current mouse speed setting:

defaults read .GlobalPreferences com.apple.mouse.scaling

or

defaults read -g com.apple.mouse.scaling

3. To increase the speed, enter a new scaling value like so. The default is 3 – try something between 4-12:

defaults write .GlobalPreferences com.apple.mouse.scaling 8

or

defaults write -g com.apple.mouse.scaling 5

4. When ready, quit Terminal and reboot your Mac for the new setting to take effect.

That’s all there is to it! Once your system restart, you’ll instantly notice how much faster and more responsive your mouse movement is.

The reason this works is it overrides the default scaling value set by Apple. They configure the Magic Mouse Speed out of the box to be slower than the maximum speed allowed in System Preferences. But with this quick terminal command, you can boost it well beyond the standard limit.
