When your Mac display and Apple TV are awake, choose your TV from the AirPlay status menu in the menu bar. You can then use the same menu to:
- Mirror your Mac display or use your TV as a separate display that extends the desktop of your Mac display.
- Turn off (disconnect) AirPlay. Pressing the Menu button on the Apple TV remote also turns off AirPlay.
If you don't see the AirPlay icon in your menu bar, make sure that your Apple TV is awake
If AirPlay stutters or disconnects by itself:
- Your wireless network might be too busy or have too much wireless interference to maintain the AirPlay connection. Learn how to troubleshoot Wi-Fi connectivity issues.
- Try making more memory available by quitting one or more apps or installing more RAM. You can use the Memory tab in Activity Monitor to help determine whether your Mac needs more memory.
