How to Set a Video as Your Wallpaper on Mac (Free)

What macOS Can Do on Its Own

System Settings includes Apple's own Aerial and dynamic wallpapers. As documented in Apple's desktop picture guide, that picker does not let you choose an arbitrary MP4 or MOV from disk.

You cannot click an "Add Video" button in System Settings to pick a personal clip. A wallpaper app can play your own file on the desktop instead.

To run your own MP4 or MOV clips as live desktop backgrounds, you need an application designed to render hardware-accelerated video frames directly onto the desktop layer.

Set a Video as Wallpaper with Moonleaf (Free)

Moonleaf is a native macOS application engineered in pure Swift and AppKit. It uses Apple's native AVFoundation framework for hardware-accelerated video decoding with minimal energy consumption.

1. Install Moonleaf

You can install Moonleaf quickly using Homebrew or by grabbing the pre-compiled DMG package:

brew install shiquda/moonleaf/moonleaf

Alternatively, download moonleaf.dmg directly from the GitHub Releases page, mount the disk image, and drag moonleaf.app into your /Applications folder.

Security note: All official Moonleaf releases are signed with an Apple Developer ID and notarized by Apple. Gatekeeper verifies the cryptographic ticket automatically upon first launch.

2. Add Your MP4 or MOV Video

Launch Moonleaf. It sits conveniently in your menu bar. Open the manager window by clicking the menu icon and selecting Open Manager.

To add video files:

1. Click the blue + add wallpaper button in the top toolbar and choose file.
2. Alternatively, simply drag and drop any .mp4 or .mov file from Finder into the Moonleaf window.

Moonleaf automatically indexes the video, parses its dimensions and file size, and generates a preview thumbnail.

3. Choose a Display and Set Wallpaper

Click on any video card to launch the Quick Preview overlay. The player loops your video in full resolution, displays the playback duration, scrubber bar, and provides a desktop clock preview.

To apply the video to your desktop:

1. Hover over the video card in the manager grid.
2. Click the magic wand icon (Set Wallpaper).
3. If multiple displays are attached, select All or choose an individual display number (1 or 2).
4. Your video immediately begins playing seamlessly on the desktop.

4. Shuffle, Adjust Volume, and Unset from the Menu Bar

With Moonleaf running, you can manage playback without reopening the main window:

• Volume Slider: Adjust video audio levels directly from the menu bar or card slider.
• Shuffle Now: Instantly rotate to another video or picture in your library.
• Automatically start wallpaper on login: Keep your video wallpaper active across restarts.
• Unset Live Wallpaper: Immediately pause and clear the video, restoring your default macOS picture.

Where to Find High-Quality Video Wallpapers

A looping clip at a clean resolution is easier to live with. Places to look:

• Your Own Video Clips: Drone footage, landscape recordings shot on your iPhone, or rendered 3D motion graphics in 1080p or 4K.
• In-App Pexels Integration: Moonleaf includes integrated browsing for Pexels. By providing a free personal Pexels API key, you can search and download thousands of curated stock videos directly inside Moonleaf.
• In-App Wallhaven Integration: For still images to mix with your videos, Moonleaf connects to Wallhaven out of the box with no API key required.

Licensing reminder: Always verify creative commons or commercial reuse rights when downloading footage published by digital creators.

A Different Video on Every Monitor or Desktop

Multi-display workflows are first-class in Moonleaf:

Multi-Monitor Independence

When you connect external monitors, Moonleaf's wallpaper cards display an interactive monitor selector. You can assign an ultra-wide panoramic loop to your external display while keeping a subtle ambient animation on your MacBook screen.

macOS Virtual Desktops (Spaces)

Moonleaf's video playback daemon (glasswp) positions its rendering layer at desktopWindow + 1 with the .canJoinAllSpaces collection behavior. This ensures your video continues playing smoothly without stuttering or reloading as you switch between virtual desktops.

GIFs Work Too — No Converting Required

If you have animated GIF loops in your collection, you do not need to convert them to MP4 files. Moonleaf plays raw .gif files natively using Core Animation.

Battery, CPU, and Performance

Moonleaf plays video with AVFoundation. In our test on an M1 Pro running macOS 26.7.1, CPU stayed under 1% while playing a 1080p MP4. That is one machine and one file. We did not measure battery life on other Macs.

Other Ways to Get a Live Wallpaper on Mac (Trade-Offs)

Prices and system requirements below are copied from each project's own page, as of Nov 2026. Check their site before you rely on them. A cell is — when that page did not state the fact.

moonleaf is a free, open-source option for playing your own files on the desktop. It requires macOS 12 or later; we tested it on macOS 26 Tahoe. It does not change the lock screen.

Troubleshooting Common Video Wallpaper Issues

1. Video fails to import or play

Ensure your video is encoded in standard MP4 or MOV formats using H.264 or HEVC codecs. Container formats like WebM, MKV, or AVI are not supported by macOS AVFoundation and will not appear in the library.

2. Audio is playing unexpectedly

If your video file contains an audio track, Moonleaf enables volume controls. Click the Moonleaf menu bar icon and adjust the volume slider, or drag it all the way to the left to mute.

3. Security prompt on first launch

Official releases are code-signed and notarized by Apple. If your Mac enforces custom corporate policies, right-click moonleaf.app and select Open, or run:

xattr -dr com.apple.quarantine /Applications/moonleaf.app

4. Wallpaper does not restart after logging in

Ensure you have enabled Automatically start wallpaper on login in the Moonleaf status bar menu.
