Step away while an AI agent, build, or render keeps running. Press ⇧⌘L and Warden blocks keyboard, mouse, trackpad, and gestures on every display, so a bumped key, kid, or cat can’t interrupt. Show progress or blur the screen, keep the Mac awake, and unlock with Touch ID or your password. It guards against accidental input; it doesn’t replace the macOS lock screen. 7-day free trial, then $8.99 once for up to 3 Macs. macOS 15.2+.
