How to force Mac (Yosemite) to use USB Bluetooth instead of internal? [duplicate]

I'm on an older Mac Pro, and I bought the ASUS USB-BT400 so that I can use Yosemite's Handoff feature. The problem is, I don't know how to disable the internal Bluetooth and force my machine to use the USB Bluetooth instead. I searched around but didn't find anything that worked.

Solution 1:

Continuity Activation Tool is a great app for doing all of the command-line stuff necessary to enable Continuity, and it claims to be able to work with USB dongles.

Solution 2:

To force your system to use an external Bluetooth controller instead of the internal one, open Terminal and type:

sudo nvram bluetoothHostControllerSwitchBehavior=always

then reboot. To revert to the default OS X behavior, type:

sudo nvram -d bluetoothHostControllerSwitchBehavior

You may need to turn off (or un-pair) Bluetooth accessories that are currently using your internal Bluetooth controller, as they can prevent the dongle from being detected by the Continuity Activation Tool.
