AirPlay destinations not appearing in list on Mac

Hello Apopgirl,

Thanks for reaching out to Apple Support Communities. We see you have some questions about AirPlay on your Mac, and we'd like to help. The following link may be able to help explain more about how to use screen mirroring with your Mac, and what devices are compatible: Use AirPlay to stream what’s on your Mac to an HDTV - Apple Support

If you need further help, please follow the steps below from this Apple resource for AirPlay issues: If screen mirroring or streaming isn't working on your AirPlay-compatible device - Apple Support

"Try these steps first

After each step, see if you still need help. 

1. Make sure that your AirPlay-compatible devices are turned on and near each other.

2. Check that the devices are updated to the latest software and are on the same Wi-Fi network. 

3. Restart the devices that you want to use with AirPlay or screen mirroring.

If you're prompted to enter a password, you might have restrictions turned on, or you might need to adjust your AirPlay password settings.

If your music unexpectedly stops

If your music stops playing unexpectedly, use your device or Siri to start playing music again. In some situations, the Home app might be using your HomePod,* Apple TV, or AirPlay-compatible speaker as the main audio source for streaming music (even if your HomePod* or Apple TV isn’t currently playing music). Using Siri on that device or performing another task might cause playback to stop everywhere. You can also use an iOS device or computer with iTunes as an audio source to manually stream music instead.

If you see video but don't hear audio

If you don't hear audio when streaming video from your iOS device or Mac to your Apple TV, make sure that the volume is turned up and not muted on both your iOS device and your television or receiver. 

If you're streaming video from an iPhone or iPad, check the Ring/Silent switch. If it's set to silent, you'll see an orange line. Toggle the switch to turn on the ringer.

If you still can’t use AirPlay after trying these steps, contact Apple
