How do I set a video wallpaper on Mac?
You can’t set video wallpapers using macOS alone. Apps like Wallper allow you to apply video wallpapers to your desktop and lock screen.
To set a video wallpaper on macOS, install the Wallper app, open it, and either pick a wallpaper from the built‑in library or drag in your own video file. Click Apply and the video becomes your desktop background instantly on all connected displays.
You can also schedule different wallpapers for day and night, set per‑display wallpapers on multi‑monitor setups, and sync the lock screen to the desktop from the same menu. Everything runs natively on Apple Silicon with hardware‑accelerated decoding.
