ProximityLock

ProximityLock is a security tool for macOS 14 and later that automatically locks your computer when you step out of range. It is designed for users in open offices or coworking spaces who need reliable security without constantly setting short screen lock timers. It monitors the Bluetooth signal strength of your linked Apple device (iPhone or Apple Watch) to determine distance.

This tool ensures your Mac is secure by using system-level APIs for guaranteed screen locking. Key features include:

• Automatic Locking: Locks the Mac immediately when the linked device moves out of range.
• Adjustable Sensitivity: Customize the proximity threshold and auto-lock timeout delay.
• PIN Protection: Requires a PIN to change settings or quit the application, adding an extra layer of security.

The application uses Bluetooth Low Energy (BLE) for minimal battery impact and is signed and notarized by Apple. It is available for a 14-day free trial, followed by a one-time purchase of $19.99, with the license covering use on an unlimited number of personal Macs.
