We just launched Wallspace here - a native macOS app that lets you use cinematic 4K live wallpapers on your mac and lock screen.
Wallspace started as a small side project after noticing that most wallpaper apps on macOS either felt heavy, outdated, or poorly integrated with the system.
Wallspace brings cinematic live wallpapers to macOS, designed to feel smooth, minimal, and native. Instead of static backgrounds, your desktop and lock screen can come alive with carefully curated video wallpapers that loop seamlessly while staying light on CPU and battery.
Wallspace focuses heavily on performance and simplicity, so wallpapers run quietly in the background without slowing down your Mac.
