Wallper
Wallper is a macOS live wallpaper app that lets you set animated video backgrounds on the desktop and, on supported systems, the Lock Screen.
What is Wallper?
Wallper is a native Mac utility for applying animated video wallpapers to the desktop and, on supported macOS versions, the Lock Screen. It is designed for users who want a more dynamic desktop without relying on browser-based tools or complex customization steps. The app includes a built-in library of live wallpapers, supports browsing and applying downloaded content, and also lets you use your own media. Wallper focuses on Mac-specific behavior such as pausing during fullscreen use, reducing resource use on battery, and adapting playback for different hardware. It fits best for users who enjoy desktop personalization, multi-display setups, and video-based backgrounds that feel integrated with macOS. Wallper is published by Dmytro Katyukha.

Safety overview
Status: Mostly safe
Wallper is a legitimate personalization app for macOS. Access to wallpaper-related system features is normal for its purpose, and using your own local media is an expected part of how the app works. Removing the app will stop its live wallpaper features, and any downloaded wallpaper content may no longer be available inside the app unless you keep the media files separately. As with any app that downloads online content, use the built-in settings to manage resource use and review what you store locally.
Recommendation: Keep Wallper if you actively use animated wallpapers or Lock Screen video backgrounds on your Mac. If you no longer use those features, you can remove it with little impact beyond losing its wallpaper library, playback controls, and related personalization options.
