1
Open the disk image
Drag Skywall onto the Applications folder beside it. That is the whole install.
2
Launch it once
Skywall lives in the menu bar. No icon in the Dock, nothing to configure.
3
Pick a film
It plays behind your windows on every display and keeps playing while you work.
Where the films come from
They are not in the download. Pick one and it arrives from the system’s own content servers, into the folder macOS already keeps them in, so nothing is stored twice and nothing is re-encoded. Skywall has no servers of its own.
In this build
Added
- Low Power Mode now pauses the wallpaper. Turn off Pause in Low Power Mode in Settings to keep it playing at half speed instead.
It is a beta, so tell me what breaks.
The feedback form reaches the developer directly, and the issue tracker is the same thing in the open.
