Bluetooth (System Preferences)

The Battery pane of the System Preferences in macOS was developed by Apple to allow users to manage connections with Bluetooth devices to their Mac.

History
Bluetooth was first released as a technology preview in 2002 with support for 3rd-party USB adapters. It was later integrated into Mac OS X 10.2 (Jaguar) and appears when Bluetooth hardware is installed. Bluetooth is now a standard feature of all Macs.

There was a 3rd-party attempt to create a Bluetooth Control Center for older Macs running Mac OS 9, but work on the driver was not completed and the source code was released in 2005. Another option for PowerPC-based systems is to launch classic Mac OS software in the Classic environment so that Mac OS X handles Bluetooth devices.
