About Bouncer
Bouncer is a menu bar theft alarm for Apple silicon MacBooks. Arm it before stepping away, and its motion sensors watch for a lift. If the Mac moves, Bouncer locks the screen, sounds warning beeps and then plays a siren through the built-in speakers. Unlocking with Touch ID or a password disarms it.
Bouncer is designed for people who leave a MacBook unattended in public places. It uses the Mac’s built-in accelerometer, gyroscope and lid sensor, with no drivers or kernel extensions. Sensor readings stay on the Mac; optional email alerts can send photos and location when an alarm sounds. Requires macOS 14 or later.
