How to get Mac and Bluetooth in place
Activate the Bluetooth menu by holding down Shift+Alt simultaneously, the command we are interested in appears: Debug.
Or at least it should appear: if there is no Bluetooth device already paired with the Mac, it may remain hidden.
In order of "severity" of intervention for Bluetooth problems:
- Remove all devices to reset the pairing settings and start over;
- Restore factory settings to restart from "clean" Mac and peripheral configurations;
- Restore the Bluetooth module.
