How to Set a Looping Video as a Mac Desktop Wallpaper

Does macOS support video wallpaper natively?

No. macOS lets you choose from Apple's built-in dynamic wallpapers and aerial scenes (shot from above cities, landscapes and oceans), but it does not include a setting to load your own video file as a desktop background. To use a custom looping MP4, you need a third-party app that renders the video behind your icons and windows.

This is different from Apple's "Screen Saver" category, which does let you pick aerial or landscape motion scenes, including as a screen saver proper. That built-in option is worth knowing about separately from desktop wallpaper, and we cover it below.

What Apple's System Settings actually offers

Open System Settings > Wallpaper on a current macOS release and you will see categories including:

• Dynamic wallpapers (static images that shift with time of day)
• Apple aerial scenes (looping drone-style footage of oceans, landscapes and cities)
• Your own photos, as static images only

There is no "add video" button in this panel. The aerial scenes are Apple-produced and cannot be swapped for your own file through System Settings.

Using Apple's aerial wallpaper as a screen saver

If you just want looping motion on your screen when idle, you don't need a third-party app:

1. Open System Settings.
2. Go to Screen Saver.
3. Choose one of the Aerial or Landscape categories.
4. Set your idle time under Lock Screen settings if you want it to trigger automatically.

This plays only while the Mac is idle or locked, not while you're working at the desktop. For a background that shows behind your icons while you work, you need a dedicated app.

How third-party video wallpaper apps work, in general terms

Several third-party apps on macOS are built specifically to loop a video file as a live desktop background. In general, they work the same way:

1. Install the app from the developer's site or the Mac App Store.
2. Grant permissions the app requests, typically Accessibility or Screen Recording access under System Settings > Privacy & Security, since the app needs to draw content below your desktop icons.
3. Import your video file, usually by dragging the MP4 into the app or pointing it to a folder.
4. Set it as active, which places the video on the desktop layer, behind icons and windows, looping continuously.
5. Choose display behaviour, such as which monitor to use if you have more than one, and whether it pauses when another app is in full screen.

Because the app is doing continuous video decoding, it uses more CPU and GPU than a static image or Apple's native aerial option, which is why battery and performance matter here.

Battery and performance tips

• Prefer a laptop on power when running video wallpaper for long sessions. Continuous decoding drains a battery noticeably faster than a static wallpaper.
• Match resolution to your display. A 4K loop on a 1080p screen wastes GPU cycles for no visible benefit; downscale or pick the 1080p version if that is what your Mac's screen uses.
• Check for a pause-on-full-screen or pause-on-battery option in the app's settings. Many include one, and switching it on stops the video while you're in a full-screen app or unplugged.
• Close the wallpaper app when not needed. If you're doing demanding work (video export, gaming), quitting the app temporarily frees up resources.
• Watch Activity Monitor if your Mac feels warm or the fan is running more than usual. The video wallpaper app will show up under CPU or GPU usage there.

Where to find loops for this

Browse by theme if you want something specific for a Mac desktop: rain, fireplace, lofi study, night sky, snow and forest. Or see the full animated backgrounds collection.

If you also want a similar loop for other setups, see our guides on using a video background in Zoom, setting one on Windows desktop, using one in OBS Studio, or as a phone wallpaper.

Frequently asked questions

Can I set an MP4 as my Mac wallpaper without installing anything?

No. macOS has no built-in setting to use a custom video file as a desktop background. Apple's native options are limited to aerial and landscape scenes it provides, plus static photos. A custom MP4 requires a third-party app.

Will a video wallpaper drain my MacBook's battery faster?

Yes, noticeably, since the system has to continuously decode and render video rather than display a static image. Running on power, lowering resolution to match your screen, and using a pause-on-battery setting if the app offers one all help.

Is Apple's aerial screen saver the same as a video wallpaper?

No. The aerial screen saver only plays when your Mac is idle or locked. A video wallpaper app keeps the loop visible behind your icons while you are actively working at the desktop.

Can I use a 4K loop on any Mac?

You can, but it only makes a visible difference on a 4K or higher-resolution display. On a standard 1080p screen, a 1080p version looks the same and uses fewer resources.
