Lock any Mac app behind Touch ID, zero permissions
4.8(6)2PrivacymacOSMenu Bar Apps
Shoo! is a macOS menu-bar app that locks any application behind Touch ID, Apple Watch, or a backup password. It prevents a protected app from rendering until you authenticate, and rechecks on every app switch — without requesting Accessibility or Screen Recording permissions. Runs fully offline, collects no telemetry, and is a one-time purchase with free updates.

Built Shoo! after handing my Mac to someone for "just a sec" one too many times and realizing every app-locker on the market only checks your password when the app launches — not when you switch back to it. Shoo! actually quits the protected app and relaunches it behind Touch ID, so there's no overlay to bypass and no window that stays unlocked in the background. Zero permissions needed (no Accessibility, no Screen Recording). Happy to answer any questions!
I've spent a lot of time looking for this app. It solves my case at work whenever I have to share my laptop with workmates. Great app. Thank you.
