MuGen Wallpaper vs Vivid Walls

MuGen Wallpaper is a macOS desktop app for dynamic video and programmable web wallpapers. It supports multiple screens, and web wallpapers can receive system utilization and screen-index information. Video speed and volume controls are included in both tiers. Playback can pause when every screen is in fullscreen mode, and the app can launch at startup. The maker says video playback uses Apple Silicon for efficient playback and lower power consumption. The MuGen Wallpaper Community lets users download and share wallpapers, with uploads reviewed before publication. Web wallpapers may opt into weather updates through OpenWeatherMap, using a supplied API key and location access, but they are limited to local resources and cannot call external APIs directly. The free plan costs nothing and allows up to 10 dynamic wallpapers. An unlock is a one-time in-app purchase with no listed price and no wallpaper limit. Community registration collects an iCloud identifier and associated Apple ID email; tokens and the weather key are stored in Keychain.

Vivid Walls is a native macOS app for Wallpaper Engine scene files and video, web, GIF, and image wallpapers. It renders scenes on Apple Silicon with a Metal scene engine. Wallpapers can react to cursor movement, clicks, system audio, or focus modes. Users can span a scene across displays or set independent scenes, then schedule them by time of day or focus mode. The app pauses when the desktop is fully covered or another app is fullscreen, reduces its frame rate on battery, and respects Low Power Mode. Eight animated 1080p wallpapers are loaded into the library at first launch. A free Windows Companion transfers a Wallpaper Engine library to the Mac over local Wi-Fi using a four-character code. The free plan keeps the bundled wallpapers; the Full Library costs $9.99, paid once. The app requires macOS 14.0 or later and Apple Silicon M1 or later, and does not support Intel Macs. The maker says some scenes may render incorrectly because of their varied effects and content.
