Mouse on fire

The Mouse Acceleration PrefPane is a GUI and startup item to Richard Bentley’s MouseFix. You can set up an extended speed parameter and acceleration curve for your mouse and touchpad.

  • Increase mouse pointer precision
  • Speed up your mouse movement
  • Set mouse acceleration parameter
  • Full control with just two simple knobs

History & Notes

For some time I’ve been offering a Preference Pane build around the OS X MouseFix by Richard Bentley. The API changed a bit with the release of 10.5 Leopard and then 10.6 Snow Leopard. It got worse each time. It’s limited to just a simple speed setting now. With a trick you can disable the acceleration, but that’s it.

Only the original version 1.0 is with explicit acceleration settings. With the current version try a inverted setting at about -1.0x.

See the older OS X Daily article for alternatives.

Get the current release

64bit (Intel) / arm64 (M1) binary
for macOS Mojave, Catalina, Big Sur, Monterey

Note: The app is not signed by a paid Apple certificate. Check that the download is genuine from the official site, then follow Apple’s Open a Mac app from an unidentified developer:

“If you try to open an app that isn’t registered with Apple, you get a warning dialogue. This doesn’t necessarily mean that something’s wrong with the app.”

  • Control-click (right-click) the app icon, then choose Open from the shortcut menu.
  • In the dialog now click Open. You only have to do this once.

The Preference Pane is self contained. If you want to uninstall, you only need to locate the Preference Pane and delete that. Current setting persists until the next logout or restart. The preference pane just sets the value once, like the built-in pane. If you use the built-in “Mouse”-pane the settings should be back to normal.

Find and delete it in your users Library / PreferencePanes. That’s like any other preference pane, just remove it from ~/Library/PreferencePanes/Mouse Acceleration.prefPane Nothing else is installed. It’s a clean uninstall that way :)
