KeyboardCleaner is a macOS app for disabling your input devices temporarily — perfect for cleaning your keyboard without having to shut down!
Once you start KeyboardCleaner, your screen will turn blank and display a message showing that the keyboard and mouse have been disabled. To re-enable them and close KeyboardCleaner, hold down right click for one second and release.
If you are running KeyboardCleaner for the first time, you may need to grant it accessibility access. Usually, macOS will show a system dialog with instructions to do so. If it does not, go to System Preferences > Security & Privacy > Privacy > Accessibility and grant KeyboardCleaner access.
KeyboardCleaner creates an event tap to disable input. If you are running software that detects (and possibly terminates) programs doing this, you might need to whitelist KeyboardCleaner.
While working on KeyboardCleaner, you should keep the AutoKill script running in the background. To do so, run:
./util/auto-kill.sh <limit>
The script will check for the KeyboardCleaner process every 2 seconds and send SIGKILL if its running time exceeds the <limit> argument (seconds). This is useful to avoid needing to force restart your device if you make a change that prevents you from deactivating KeyboardCleaner normally.
This program does not automatically clean your keyboard. It only assists in the process of doing so.
