Here is a step by step walkthrough on how to pair the AirTurn BT-105 or DIGIT with a Bluetooth-equipped Mac computer. These screenshots were taken from a MacBook Pro running OS X (10.6)

Before you begin pairing, turn your BT-105 on.

On your Mac computer, go into System Preferences, then click on "Bluetooth" within the "Internet & Wireless" settings:

If you don't have any other Bluetooth devices paired with your Mac, you will see the following screen:

Click on "Set Up New Device..." to begin pairing with the BT-105. (NOTE: In Mac OS 10.5.8, when given the option in the Blueooth setup tool, check "Any Device" and NOT "Keyboard.")

On the other hand, if you already have another Bluetooth device paired with your Mac, you may see the following screen:

To add the BT-105, click on the "+" button on the lower corner of the left screen.

After a short pause, you should see the AirTurn BT-105 as one of the discovered Bluetooth devices as follows - it will appear as a Keyboard under the "Type" column:

Click on "Continue". (NOTE: In Mac OS 10.5.8, when given the option in the Bluetooth setup tool, check "Any Device" and NOT "Keyboard.") You will then see the next screen for a few moments as the Mac computer attempts to pair with the BT-105:

You may see the Keyboard Setup Assistant that states that the keyboard cannot be identified. Ignore the message and click on "continue:"

The Keyboard Setup Assistant may ask you to press a key. You can ignore this message and just close the window by pressing the red window button on the top corner. (Note: In Mac OS10.5.8, if you are taken to a screen that gives a Passkey option, click on the Passkey option and choose "empty," then continue. The Bluetooth setup tool will then look at the BT-105 and say that the BT-105 wants a Passkey. Type in "0000." The Mac will then pair with the BT-105.)

Note: if you are asked to enter a passcode for your Bluetooth device, enter "0000" (four zeros).

The next screen will congratulate you for setting up your new bluetooth keyboard (the BT-105):

You will now see the AirTurn BT-105 as one of your recognized Bluetooth devices within your Mac's Bluetooth settings:
