How to set Utah’s Cathedral Canyon as your wallpaper.
- Install Skywall and open it from the menu bar.
- Find it under Landscapes.
- Click the card. If the film is not on your disk yet, Skywall downloads it from the system’s own content servers into the folder macOS already uses.
- It plays on every display until you pick another one.
The film goes into the system’s own Aerials folder and stays there if you remove the app. Skywall has no servers of its own; nothing is uploaded anywhere.
