I reverse engineered Apple's video wallpapers

A developer has created Phosphene, a macOS app that enables users to set custom videos as desktop and lock screen wallpapers by reverse-engineering Apple's private WallpaperExtensionKit framework. The tool integrates directly into macOS's native wallpaper settings and includes features like gapless looping, multi-display support, and power-aware playback that adjusts based on thermal state and battery level. The app requires macOS Tahoe (26.0+) and is available on GitHub and Homebrew, though it uses private APIs that Apple could change in future updates.
