KensingtonWorks on macOS Big Sur

I’m using an Expert Mouse Wireless Trackball over Bluetooth.

NOTE: I’ve updated this for macOS Monterey. The instructions should be the same.

To Uninstall Old Software

1. Go to System Preferences → Right-click on Kensingtonworks → Remove
2. Finder → Go to Folder → ~/Library/Preferences
3. Finder → Go to Folder → ~/Library/Application Support and remove the folder KensingtonWorks
4. Remove com.kensington.kensingtonworks2.app.plist and TbwSettings.json
5. Run Finder → Applications → Utilities → KensingtonWorks Uninstaller
6. Restart!

To Fresh Install

1. Go here and download the latest version (v3.0.4). I cached it here as well in case some intrepid PM at Kensington decides to fuck with their website and download links again¹.
2. Run it. It will get stuck at some point.
3. Go to System Preferences → Security and Privacy → General and unblock it
4. Install should complete
5. Go to System Preferences → Security and Privacy → Privacy → Accessibility → check KensingtonWorks Helper (it should be checked after installation.)
6. Restart
7. Launch KensingtonWorks
