Apple does not let you set a video file as your desktop background out of the box. MacWall solves this with native hardware decode — your video plays behind Finder windows, loops cleanly, and respects battery and full-screen rules.
Supported formats
- MP4 and M4V (H.264 / HEVC)
- MOV (QuickTime)
- GIF (short animated loops)
- 4K and ultrawide aspect ratios
Import workflow
- Download and open MacWall.
- Go to Library → Import, or drag a file onto the app window.
- Preview the loop, then set as desktop wallpaper.
- Use the menu bar to pause when you need maximum performance.
Tips for smooth playback
- Prefer H.264 or HEVC encodes — MacWall decodes on the GPU.
- Shorter loops (30–120 seconds) feel more natural than hour-long files.
- Enable pause-on-battery if you work unplugged often.
- Use one wallpaper per display on multi-monitor setups.
