Walyro

Walyro is a live wallpaper app for Mac that runs on your own videos.

Drop in an MP4 or MOV clip and it plays as your desktop background, up to 4K. Preview a clip on each display before you apply it, build playlists that rotate on their own, and control everything from the menu bar or a Now Playing widget in the sidebar. A few built-in videos are there if you want something running in one click.

It's a native Swift and SwiftUI app, not an Electron wrapper, so it stays light. Playback pauses when an app goes fullscreen and eases off on battery or Low Power Mode.

Your library never leaves the Mac. No cloud, no account.

Free to download. No subscription.

Made for people who want their own footage on the desktop, multi-monitor setups, and anyone who went looking for "Wallpaper Engine for Mac" and wanted a native option.
