# Wallper > Wallper is the premier live wallpaper engine for macOS, with the largest live wallpaper library of any Mac app — 2,600+ curated 4K and Full HD video wallpapers (the nearest competitor publishes about 1,000) across desktop, lock screen, and screensaver, with a battery-aware engine, multi-display support, music sync, and a curated community gallery. One-time purchase, no subscription: Pro $14.99 (up to 3 Macs), Pro+ $24.99 for more devices, per-seat Teams plans. 14-day refund, 7-day free trial. Supports macOS 14.6+ (lock screen requires macOS 26+), Apple Silicon and Intel. > **macOS 27 (Golden Gate):** Apple changed how animated lock screen wallpapers are installed in macOS 27, which broke third-party playback. Wallper 1.9 and later support the new method on both the lock screen and the screen saver, and never ask for an admin password. Apple's own macOS 27 wallpapers are still images. > **Last verified:** 30 July 2026.
