MacBook Air is already configured to use a wireless technology called Bluetooth. In the rest of this chapter, I cover what Bluetooth is; how to connect MacBook Air with various Bluetooth devices, such as a mouse, keyboard, and headset; and how to exchange files using MacBook Air’s Bluetooth capabilities.
