How to Use AirPlay to Stream Peacock TV from charles hensen's blog

Another route for compatible smart TVs is AirPlay streaming from a Mac or iOS device.

Macs running macOS Mojave (10.14.5) and iOS devices operating on iOS 12.3 and later support AirPlay video streaming.

1. Log in to your Peacocktv.com/tv account or open the app on your device and queue up the content you want to stream.

2. On a Mac, select the AirPlay icon in the menu bar to connect your device to a compatible smart TV. 

3. Press Play and make any adjustments to the display from the AirPlay drop-down menu on your Mac, which is highlighted blue when turned on.
