Can Airplay from Macbook on Apple TV but not Airplay Mirroring

Requirements for using AirPlay

Here's a quick way to find out if your Mac supports AirPlay: Choose Apple () menu > System Preferences, then click Displays. If you don't see a “Show mirroring options in the menu bar when available” checkbox, your Mac doesn't support AirPlay.

Minimum requirements if your Mac and Apple TV are on the same network:

• Apple TV (2nd generation or later) with the latest Apple TV software
• And any of these Mac computers with OS X Mountain Lion v10.8 or later:
  • iMac (Mid 2011 or later)
  • Mac mini (Mid 2011 or later)
  • MacBook (Early 2015 or later)
  • MacBook Air (Mid 2011 or later)
  • MacBook Pro (Early 2011 or later)
  • Mac Pro (Late 2013 or later)

To find out what network your Apple TV (4th generation) is using, go to Settings > Network. On earlier Apple TV models, go to Settings > General > Network. The Apple TV should be on the same network as your Mac.

Minimum requirements for peer-to-peer AirPlay, which lets visitors connect their Mac or iOS device to your Apple TV without passwords or connecting to your Wi-Fi network:

• Apple TV (3rd generation rev A, model A1469 or later) with the latest Apple TV software
• Mac (2012 or later) with OS X Yosemite v10.10 or later
