NothingHere

NothingHere is a macOS utility designed as a panic button that instantly cleans your screen with a single key press. It performs three actions simultaneously: hiding all application windows, muting all system audio, and opening a pre-configured cover document to disguise non-work activities. This tool is free, open-source, lightweight at ~5.9 MB, and runs on macOS 15.0 and above, with Guard Mode in the menu bar for constant readiness.
