I'm having trouble forcing my mac to stay connected to my external USB Bluetooth adapter on reboot/restart.
I've read quite a few posts and have found this command
sudo nvram bluetoothHostControllerSwitchBehavior=always
I was able to use Bluetooth Explorer and I switched it to the new bluetooth USB dongle but it will still not remain connected after reboot. Instead it remains disconnected and I have to reconnect it every time I restart my computer.
Machine: 2018 Mac Mini
Current OSx: Catalina 10.15.5
External Bluetooth Adapter: Asus BT400

Their are windows drivers but not for mac since it uses the same Broadcom chipset.
Is there another command that I can use that will keep it connected after reboot?
