CleanKeys
Lock your keyboard and block clicks while cleaning your Mac
CleanKeys is a free macOS utility that temporarily disables keyboard input while you clean your keyboard. Unlike similar apps, it expands to full screen and blocks mouse clicks across all connected displays, leaving only the unlock button accessible. No accidental clicks, no random shortcuts and no need to lock or shut down your Mac. It features a clean Liquid Glass-inspired interface and is especially useful on MacBooks, which don't have a keyboard lock button.
