HOW TO Stream to AirPlay devices
1 Stream audio from your Mac
Go to System Prefs > Sound > Output and choose an AirPlay device. If you have the volume displayed in the menu bar, select from there. In Big Sur, go to Control Centre > Sound, and tap the AirPlay (beacon) icon.
2 Stream from the Music app
If you only want to stream audio from the Music app, rather than every sound on your Mac, launch Music, click the AirPlay icon in the toolbar and choose your AirPlay speakers or TV from the list.
3 Stream from iPhone or iPad
With audio playing on your iOS device, swipe down from the top right of the screen to invoke Control Centre, then tap the AirPlay icon (top right). Choose the device you want to stream to from the list of options.
4 Mirror your Mac’s screen
In Big Sur, choose Screen Mirroring in Control Centre. Otherwise, go to System Preferences > Display, and choose your TV from the AirPlay Display menu. Choose Mirror Display from the menu.
5 Extend your Mac’s screen
Follow step 3, but choose Extend Mac Desktop. In System Preferences > Display, use the Display tab to set the resolution and colour for the TV. Then click Arrange and drag the screens to the order you want them.
6 Video from an iOS app
Launch the app you want to stream from, for example, YouTube. Tap the screen then tap the Cast icon. Choose AirPlay and Bluetooth devices, then choose the Apple TV or AirPlaycompatible TV you want to stream to.
7 Display photos from an iPad
Launch the Photos app and navigate to a photo you want to display. Tap the Share icon at the bottom of the screen and choose AirPlay from the list of options. Choose your Apple TV or AirPlay-compatible TV.

Swipe down from the top-right corner of the screen to bring up Control Centre. Tap Screen Mirroring and choose your Apple TV or AirPlay-compatible TV. To stop mirroring, tap Screen Mirroring and choose your iPad.
