KeyboardCleanTool →

This weekend, I was using someone else’s MacBook Pro and wanted to clean their keyboard. I could not shut it down for cleaning, as it was downloading a macOS update. This prompted me to look for an app that could lock the keyboard for me to wipe it down.

This led me to KeyboardCleanTool, a free utility by Andreas Hegenberg, the genius behind apps like BetterTouchTool.
