How to uninstall Mac Mouse Fix on Mac

Mac Mouse Fix changes your mouse through a background process, Mac Mouse Fix Helper, which keeps running after you close the app window and holds the Accessibility permission. Turn it off before you remove the app, and remove the permission entry afterwards. Your button and scrolling settings live in ~/Library/Application Support/com.nuebling.mac-mouse-fix, a folder Mole selects by default, so copy it first if you may want them back. This guide covers the app from macmousefix.com or its GitHub releases, and the Homebrew cask mac-mouse-fix.

Save your settings first

Mac Mouse Fix's source code stores its configuration as config.plist inside ~/Library/Application Support/com.nuebling.mac-mouse-fix. Copy that folder somewhere outside Library if you want the same button remaps and scroll settings on a reinstall.

Your license key came by email from Gumroad when you bought the app. Keep that email; the Mac Mouse Fix readme says the license works on all your Macs and describes no deactivation step.

Turn off the helper and remove the app

1. Open Mac Mouse Fix and turn off the Enable Mac Mouse Fix switch. That stops Mac Mouse Fix Helper, which is what actually changes the mouse.
2. Quit Mac Mouse Fix, then search Activity Monitor for Mac Mouse Fix and check that neither the app nor the helper is running.
3. Move Mac Mouse Fix from Finder's Applications folder to the Trash. The readme's uninstall section says this is how to uninstall it, and that files are left behind; the table below lists them.
4. Open System Settings › Privacy & Security › Accessibility. If Mac Mouse Fix Helper is still in the list, select it and click the minus (−) button below the list, as the author's Accessibility guide describes. The entry can stay there after the app is gone.
5. Open System Settings › General › Login Items & Extensions. If a Mac Mouse Fix entry is still listed, turn it off there.

Where Mac Mouse Fix keeps its data

Open each path with Shift + Command + G in Finder and skip the ones that do not exist. These come from the Homebrew cask's zap stanza, and the first three also appeared in the tests.

Check the result

Run these read-only commands after the app is in the Trash:

pgrep -il "mac mouse fix"
launchctl list | grep -i nuebling
ls "$HOME/Library/Application Support/com.nuebling.mac-mouse-fix"

• No output from pgrep means neither the app nor its helper is running. A listed Mac Mouse Fix Helper means the helper is still running and changing your mouse; if the app is already in the Trash, put it back, turn the switch off, quit, and remove it again.
• No output from launchctl list means no Mac Mouse Fix job is loaded in your session. A line containing com.nuebling.mac-mouse-fix.helper means the helper is still registered; check Login Items & Extensions.
• ls listing config.plist means your settings are still there, which is what you want if you kept them. "No such file or directory" means the folder is gone.

The Accessibility list has no command-line check here; look at it in System Settings.

If you installed it with Homebrew

The mac-mouse-fix cask's zap list includes ~/Library/Application Support/com.nuebling.mac-mouse-fix with your config.plist, the app and helper preferences, caches and HTTP storage, and the WebKit folder. Running brew uninstall --cask --zap mac-mouse-fix yourself moves all of them to the Trash, whatever you selected in Mole. To keep your settings, remove only the app:

brew uninstall --cask mac-mouse-fix

Mole adds --zap only when every path on the zap list sits inside ~/Library, none of them touches a row you left unchecked, and no other installed app claims them. Every path on this list is inside ~/Library, and Mole selects the settings folder by default, so if you leave the rows ticked Mole can use --zap. Untick the Application Support row to keep your settings; Mole then leaves --zap out. A Homebrew uninstall does not remove the Accessibility entry either.

What Mole lists

For Mac Mouse Fix from macmousefix.com:

• ~/Library/Application Support/com.nuebling.mac-mouse-fix is selected by default, and it holds config.plist with your settings. Untick it or back it up first if you want to keep them.
• The com.nuebling.mac-mouse-fix preferences file, HTTP storage and temporary cache are selected by default.
• Before moving the app, Mole stops the launchd jobs it finds inside the app bundle, which covers Mac Mouse Fix Helper. Mole does not edit the Accessibility list or other privacy permissions; remove Mac Mouse Fix Helper there yourself.

What this test covered

On September 23, 2026, Mac Mouse Fix was copied from the official zip on its GitHub releases page into Applications, opened once, and uninstalled with a development build of Mole with every row ticked; there was no Homebrew receipt. The app, its Application Support folder, HTTP storage and preferences went to the Trash. The Enable Mac Mouse Fix switch was never turned on, so the helper was never registered, and removing a running helper and its Accessibility entry was not tested. On September 26, 2026, it was installed again from the same download, opened once, and removed the same way. Mole's Status view showed it as one row of 2 processes, about 38 MB. All 5 items went to the Trash, no process or startup item was left, and Mole's update check found its Sparkle update feed. The helper, Accessibility permission, a license and the Homebrew cask were not tested.
