ProximityLock

What is ProximityLock?

ProximityLock automatically locks your Mac when you step away by monitoring a nearby Bluetooth device such as an iPhone or Apple Watch. It uses Bluetooth Low Energy for distance detection, offers adjustable sensitivity and auto-lock timeout. You get a 14-day free trial, then a one-time license. The app is signed by Apple, needs only Bluetooth (and optional internet for activation), and does not send your data anywhere.
