My Long Range USB Bluetooth Adapter is not working.

If your adapter is not working, first open Bluetooth preferences and delete all devices attached to internal Bluetooth, or the system will not switch to the external Bluetooth dongle. That means that you have to have a built-in or USB keyboard to complete the installation.

Also, using any Apple magic mouse/keyboard will also automatically set/use the internal Bluetooth, not external.

Using any wireless keyboard will prevent installation from occurring. Once installed via wired (non-Apple) keyboard, then a wireless peripheral may be connected.

I can't install the driver for my Long-Range USB Bluetooth Adapter

You need to first open Bluetooth preferences and delete all devices attached to internal Bluetooth, or the system will not switch to the external Bluetooth dongle. That means that you have to have a built-in or USB keyboard to complete the installation. Using an Apple Magic Keyboard or Mouse will automatically switch to internal radios, rather than external radios like ours.

You may need to use a third-party wired keyboard or mouse to complete the installation.

After using the third-party wired mouse/keyboard, try reinstalling the Sonnet driver again, and re-testing.

You may also need to manually disable the internal radio with the steps shown in step 6, page 3 of our manual here (you must use Terminal).

After these changes are made, try re-installation, and re-pairing Bluetooth devices again.
