How to cast ACE On-Demand to an Apple TV from a Mac?
- Ensure your iOS/iPadOS/macOS is connected to the same Wi-Fi network as your Apple TV. 
- If you have a macOS computer you can use AirPlay to mirror your screen to an Apple TV device that's connected to the same Wi-Fi network. 
- In the top right corner click the AirPlay icon. If you don't see this icon, go to the Apple menu in the upper left corner, then navigate to System Preferences > Displays. Select "Show Mirroring Options" in the menu bar when available. 
- Select your Apple TV. Your TV will begin to mirror your macOS screen. 
- Navigate to ace-ondemand.com and select the VOD/LIVE class in your web browser on your Mac and begin playing the video.
- Put the volume all the way up on your computer, then control volume from there on your TV. 
- To watch your form, turn on your camera and place your computer in a spot where it's filming you. 
- There may be a slight lag when you turn your camera on and/or off - it'll catch up with itself. 
- For optimal full-screen view on your TV, remain in the Speaker view and enter into full-screen on your computer. 
- After class, return to the top right corner of your macOS, click the AirPlay icon and select Stop AirPlay.
