Overview
Dynamic wallpaper on Mac, clarified
On Mac, the phrase dynamic wallpaper can point to two different things. Some people mean Apple's built-in desktop pictures that shift with time of day. Others mean a more flexible desktop with real motion from video.
Walyro is built for the second use case. It turns local MP4, MOV, and M4V files into custom motion wallpaper, so you can go beyond Apple's preset scenes and control exactly what plays on each display.

Apple's dynamic wallpaper means time-of-day changes
On macOS, dynamic wallpaper usually refers to Apple's built-in desktop pictures that change appearance throughout the day. They add variety, but they do not turn your own clips, loops, or ambient scenes into wallpaper.
If Apple's built-in scenes are all you want, you may not need another app. This guide matters when you want something more custom than the wallpapers that ship with macOS.
Apple's dynamic wallpapers use Apple's own built-in images
They change over time instead of playing your own video files
They are different from custom moving wallpaper apps
Use Walyro when you want custom motion from your own files
Walyro is built for that second case: a dynamic-looking desktop built from your own video files. Built-in starter clips are there to test the effect, but the point is running your own MP4, MOV, and M4V files instead of Apple's preset scenes.
Custom dynamic wallpaper needs real controls
Once you move beyond Apple's built-in choices, control matters as much as motion. Walyro lets you preview the crop, choose Fit, Fill, or Crop, and decide whether the wallpaper should run on every display or only one.
It also keeps playback muted by default and makes pause, resume, and clear actions easy to reach from the menu bar and the Now Playing area. That helps custom motion feel intentional instead of distracting.
Preview the desktop before you apply the video
Run motion on one display or several
Pause quickly when the desktop needs to calm down
A better fit for Mac setups that change during the day
A Mac setup rarely stays the same — undocked in the morning, plugged into a second monitor by afternoon. Walyro adapts to those changes with per-display targeting and one-click pause, so motion never gets in the way when your hardware shifts.
