Can I use Glo on my AppleTV?

Glo is available as an app on tvOS if you have a fourth-generation Apple TV or newer. With earlier versions of Apple TV, you can use AirPlay.

To connect via AirPlay please try the following:

Hit any button on your Apple TV remote to make sure it’s not sleeping.

1. From your computer: Select the AirPlay display icon from your computer's menu bar and select Connect to AirPlay Display: Apple TV
2. From your iPhone/iPad: Swipe up from the bottom of your screen to access the Control Center and select the AirPlay icon.
