AirPlay Mirroring lets you send what’s on your Mac to an HDTV wirelessly with Apple TV.
If your Mac supports AirPlay Mirroring, an AirPlay Mirroring status icon appears in the menu bar when an Apple TV is on the same network as your Mac.
For information about Mac and Apple TV requirements to use AirPlay Mirroring, see:
- Make sure your Mac and your Apple TV are on the same network.
- Choose your Apple TV from the AirPlay status icon in the menu bar.
- Choose This Mac or your Apple TV depending on how you want to match the desktop size of your Mac.
OS X automatically detects an Apple TV when it’s on the same network, and displays the AirPlay icon in the menu bar. When AirPlay Mirroring is active, the status icon is blue.
