# What is a live wallpaper?

A live wallpaper is a looping video rendered at your desktop's wallpaper layer. Here is how it differs from animated, dynamic, and interactive wallpapers.

A **live wallpaper** is a short video loop drawn where your desktop picture normally sits — behind every icon, window, and menu. Nothing about how you use the Mac changes: you click through it, windows cover it, Mission Control and Stage Manager treat it like any wallpaper. The only difference is that the image moves.

## The terms people mix up

- **Live wallpaper** — a video loop playing continuously at the wallpaper layer. Motion is the point.
- **Dynamic wallpaper** — a still image that swaps variants based on time of day or appearance mode. macOS ships several. No motion, just scheduled stills.
- **Animated wallpaper** — usually a synonym for live wallpaper, sometimes used for procedural or shader-drawn scenes rendered in real time instead of decoded from video.
- **Interactive wallpaper** — reacts to the cursor, audio, or system state. Rare on macOS and much more expensive to run, because the frames cannot be pre-encoded.
- **Screen saver** — takes over the whole screen when you are away. It is a different macOS surface from the wallpaper, even when it shows the same footage.

## Why video, not real-time rendering

A pre-encoded video is by far the cheapest way to put motion on a desktop. Every Mac has dedicated media decoding hardware, so a 4K loop can play without the CPU touching a single pixel. A procedurally rendered scene has to be computed frame by frame, every frame, forever — which is why shader-style wallpapers tend to warm up a laptop and video-based ones do not. That difference is explained in [hardware video decode](https://macwall.app/learn/hardware-video-decode).

## What makes a loop feel good

- **Seamless** — the last frame flows into the first. You are going to see this transition hundreds of times a day.
- **Slow** — drifting clouds, rain, slow pans. Fast motion in peripheral vision reads as a notification and pulls your eye.
- **Low contrast where your icons live** — busy bright areas behind desktop icons make labels hard to read.
- **Resolution-matched** — sized to your display, not above it. See [resolution and displays](https://macwall.app/learn/wallpaper-resolution-and-displays).

## On macOS specifically

macOS has no built-in way to set your own video as a desktop wallpaper, which is why apps like MacWall exist. Desktop playback works on macOS 14 and later; live Lock Screen and Screen Saver motion needs macOS 26 (Tahoe) or later, because that is when Apple exposed the APIs third-party apps use. More on that in [how macOS wallpapers work](https://macwall.app/learn/how-macos-wallpapers-work).

## Frequently asked questions

### Do live wallpapers slow down a computer?

A video-based live wallpaper decoded on media hardware costs very little, and a well-built app pauses it whenever nothing is visible. Real-time rendered or browser-based wallpapers are the ones that cost real performance.

### Can a live wallpaper have sound?

It should not. Wallpaper audio would play constantly under everything you do, so live wallpaper apps mute the track or strip it entirely.

### Is a live wallpaper the same as a screen saver?

No. A wallpaper sits behind your windows while you work. A screen saver replaces the screen when you step away. macOS treats them as separate surfaces, though both can use the same video.
