Hi HN, I'm the creator of Muro. It’s a 100% free, open-source (MIT) live wallpaper app for macOS.

I wanted a live wallpaper app without subscriptions, paywalls, or heavy resource usage. Muro is built natively with Swift, SwiftUI, and Apple’s hardware video decoder—absolutely no Electron or web views. It normally uses around 2% CPU while playing and automatically pauses when the wallpaper isn't visible (during full-screen apps, display sleep, Low Power Mode, etc.).

I just released version 3.0, which adds the three things people have been asking for most:

1. Automations: Change Live wallpapers on a timer or by the clock (e.g., set specific hours for different wallpapers using a draggable timeline). 2. Pause After: Let a Live wallpaper play for a minute after it changes, then hold on a frame so it uses zero CPU. 3. Lock screen support fixes: Live Wallpapers now reliably play on the lock screen (macOS 14+).

The app includes a catalog of up to 100 + Live wallpapers that updates over the air, but you can also import your own videos. Everything is unlocked, and there is no account required.

I'd love to hear your feedback, bug reports, or feature requests! Download: https://github.com/MrRockySL/Muro/releases/latest
