AirPlay

2. Click on the "" Apple menu icon, then choose "System Preferences".
3. From the "System Preferences" window, then choose "Displays".
4. Select the "Arrangement" tab.
5. Click the drop-down box next to "AirPlay Display", and select the appropriate AirPlay device. Tick the checkbox next to "Show mirroring options in the menu bar when available" (See macOS Figure 5).

   • To mirror the display, click the AirPlay icon, and under the connected display, choose "Mirror Built-in Display".
   • To use the TV as a separate display, click the AirPlay icon, then choose "Use As Separate Display".
