Takeshi Sone has generously crafted and shared (under an MIT license) BLEUnlock, "a small menu bar utility that locks and unlocks your Mac by proximity of your iPhone, Apple Watch, or any other Bluetooth Low Energy device." Unlike Unlox (formerly MacID), no iOS app is required and scripting is supported. Vital for protecting data from laptop snatchers. For a wired solution, see Introducing BusKill: A Kill Cord for your Laptop.
