How do Lock Screen wallpapers work?

Wallper hands the video to Apple’s own Lock Screen pipeline instead of overlaying the login window, so playback is native and light on resources — no daemons, no hacks. Guide: https://www.wallper.app/support/lockscreen

Wallper uses native macOS integration and hands playback to Apple’s Lock Screen system. There are no overlays, background daemons, or hacks — everything works like a built-in feature.

This ensures smooth playback, low resource usage, and full system compatibility.
