NothingHere is a macOS panic button. One hotkey, three things happen at once: 1. All windows disappear — every app gets hidden instantly 2. All sound goes silent — music, videos, everything mutes 3. A cover document opens — your pre-configured "real work" file Your screen goes from "definitely not working" to "hard at work" in milliseconds. Guard Mode sits in your menu bar — when armed, you're always one key press from a clean screen. Free, open source, ~5.9 MB. macOS 15.0+.
