How to Set a Video as Your Wallpaper on macOS
Have you ever seen a Mac setup with a stunning, looping video background and wondered, "How do I do that?"
Apple’s macOS is beautiful, but out of the box, it’s surprisingly static. While you get dynamic wallpapers that shift slowly with the time of day, you can't simply right-click a video file and choose "Set Desktop Picture."
If you want true motion—cyberpunk cityscapes, calming nature loops, or abstract 4K animations—you need a third-party solution. But be careful: many "hacks" will drain your battery and overheat your laptop.
Here is the complete guide to setting a video as your wallpaper on macOS, from the complex DIY method to the effortless, high-performance way.
The "DIY" Way (And Why You Should Avoid It)
Technically, you can force macOS to display a video as a screen saver and then run that screen saver as your wallpaper using Terminal commands. It’s a classic trick, but it comes with significant downsides.
- Convert your video: You often need to convert your video to a specific screensaver format (
.saver) using legacy tools like Quartz Composer (which is effectively dead). - Terminal Commands: You have to run a command like
/System/Library/Frameworks/ScreenSaver.framework/...to force the layer to stay behind your icons. - The Dealbreaker: This method is not optimized. It runs the video at full power, constantly. Your fans will spin up, your battery will tank, and other apps may stutter.
Unless you enjoy tinkering with Terminal and carrying a charger everywhere, this isn't a practical daily solution.
The Better Way: Use Backdrop
For a seamless experience that feels like a native part of macOS, you need a dedicated engine. Backdrop is designed specifically for this. It’s built for Apple Silicon, meaning it plays 4K video wallpapers while using virtually zero CPU (often less than 0.3%).
