Prevent accidental Cmd+Q — hold to quit, release to cancel
- Hold-to-Quit — Cmd+Q is intercepted and requires a configurable hold (0.5s–3s) before the quit goes through
- Progress Ring — Small green circular indicator appears at your cursor showing hold duration
- Protected Apps — Default protection for Safari, Chrome, Arc, Firefox, Finder, Mail, Messages, Slack, VS Code, Xcode
- Protect All Apps — Toggle to require hold-to-quit for every app
- Add/Remove Apps — Add from running apps, remove with one click
- Sound Feedback — Subtle sound when a quit is prevented
- Launch at Login — Start automatically with macOS
- Menu Bar Only — No dock icon, minimal footprint
- macOS 13.0+ (Ventura)
- Swift 5.9+
- Accessibility permission (prompted on first launch)
git clone https://github.com/markksantos/Grip.git
cd Grip
./bundle.sh
cp -r Grip.app /Applications/Or build and run directly:
swift build
open .build/debug/GripAppGrip requires Accessibility permission to intercept Cmd+Q before it reaches apps. macOS will prompt you on first launch, or grant it manually in System Settings → Privacy & Security → Accessibility.
