The best live wallpaper apps for Mac in 2026

macOS has never had a true built-in live wallpaper feature. Apple's "dynamic" wallpapers only shift between still images by time of day, and aerial screensavers aren't wallpapers at all. So if you want a genuinely animated, moving desktop on your Mac, you need a third-party app. Here are the best options in 2026, with an honest take on who each one is for.

1. Formosus — best for original, AI-generated wallpapers

Formosus generates a seamlessly looping live wallpaper from a text prompt — you describe a scene, mood, or goal, and it creates one that's yours alone, then sets it in a click. It's a native Apple Silicon app, signed and notarized by Apple (installs with no Gatekeeper warnings), and runs on Windows too. There's no subscription — the app is free and you pay per generation.

Best for: people who want a unique wallpaper made for them, not pulled from a shared library.

2. Plash — best free, web-based option

Plash is a free, open-source app that turns any website into your desktop wallpaper — useful for live web content, dashboards, or animated web pages. It's not built around video files or generation, but it's a great free way to get a dynamic desktop.

3. ScreenPlay — best for playing your own video files

ScreenPlay is a free, open-source app that plays video files as your wallpaper. If you already have the loops you want (or download them elsewhere), it's a clean way to set them.

What about Wallpaper Engine?

The most popular live-wallpaper app on Windows, Wallpaper Engine, has no macOS version — we cover the closest Mac alternative in this guide.

How to choose

• Want something original, made for you? → Formosus (AI-generated).
• Want free and already have video loops? → ScreenPlay.
• Want a live web page as your desktop? → Plash.
