One of the few desktop features that macOS users envy from Windows and Linux is live wallpaper support. Live Wallpaper for macOS, created by thusvill, fills this gap with a native Swift application that brings dynamic, video-based wallpapers to macOS with performance-optimized rendering.
Unlike resource-heavy solutions that drain battery and slow down the system, this app is built with performance as a priority. It uses Metal-rendered video playback that pauses automatically when running on battery, when full-screen apps are active, or when system resources are needed elsewhere. The result is beautiful animated desktops without sacrificing battery life or performance.
