WallTune

WallTune is a live wallpaper tool for macOS multi-monitor desktop environments.

It focuses on solving the problem that ordinary wallpaper applications can only mirror the same picture and cannot remember the physical display. It can continuously spread a panoramic wallpaper onto two, three, or more monitors, or specify images, videos, folders, scaling methods, and looping rules for each screen individually. The software uses hardware fingerprinting to identify the display, can restore the corresponding settings after disconnection, reconnection or restart, and can automatically match saved desktop configurations according to the current display topology. WallTune uses a native macOS menu bar interface, supports MP4, MOV, M4V and common image formats, and has a built-in wallpaper library, playlists, alignment assistant, smart pause, focus mode linkage and shortcut command automation. It is suitable for Mac users who use external screen, portrait screen, ultra-widescreen or frequently switch office scenes.
