Work wirelessly
Using Bluetoothยฎ technology, your Mac Pro can wirelessly connect (that is, pair) with devices such as the included Magic Keyboard with Numeric Keypad, and with devices like the Magic Mouse and Magic Trackpad, AirPods, peripheral devices, wearable sports accessories, and others.
Some included accessories may already be paired with your Mac Pro. For more information about accessories, see Whatโs included.
Connect a Bluetooth device. Turn on the device so that itโs discoverable, then open System Preferences and click Bluetooth. Select the device in the list, then click Connect. The device remains connected until you remove it. Control-click a device name to remove it.
Turn Bluetooth on or off. Click the Control Center icon 
in the menu bar, click the Bluetooth icon 
, then click the control to turn Bluetooth on or off. Your Mac Pro comes with Bluetooth turned on.
