Why is my Mac wallpaper not moving?
Four causes cover almost every case. Low Power Mode pauses wallpaper motion to save battery. The wallpaper was paused and never resumed. The video file moved, was renamed, or lives on a drive that is currently disconnected. Or the wallpaper is a still image or an Apple dynamic wallpaper, which fades between photos rather than actually moving.
Overview
Most likely causes, in order
A wallpaper that has gone still is rarely a real fault. macOS pauses motion on purpose in a few situations, and the rest of the time something has changed underneath: a file moved, a drive was unplugged, or the wallpaper was paused and forgotten about.
Run through these in order. They are arranged by how often each one turns out to be the answer, so most people stop at the second or third.
- Low Power Mode
- Pauses wallpaper motion to save battery
- Paused playback
- Check Now Playing in the menu bar
- Missing file
- Moved, renamed, or on a disconnected drive
- Wrong wallpaper type
- Apple's dynamic wallpapers fade between stills, they do not move
- Formats
- MP4, MOV, and M4V; H.264 or HEVC plays best
- Purchase
- One-time purchase, no subscription or ads
1. Check Low Power Mode
This is the one that catches most people, because nothing announces it. Low Power Mode reduces background activity to extend battery life, and wallpaper motion is exactly the kind of thing it stops.
Open System Settings, then Battery, and look at Low Power Mode. On a laptop it can be set to turn on automatically when the battery runs low, so it may have engaged without you doing anything. Switch it off and the motion should return.
2. Check whether playback is simply paused
If you paused the wallpaper during a call or a stretch of focused work, it stays paused until you resume it. There is no timer that quietly turns it back on.
Click the Walyro icon in the menu bar and look at Now Playing. Each display is listed separately, so it is possible for one screen to be paused while another is still running. Hit resume on whichever one has stopped.
3. Make sure the video file is still there
Walyro plays your file from wherever it lives on disk. Move it, rename it, or empty the folder it was in, and there is nothing left to play.
External drives are the common version of this. A wallpaper stored on a drive you unplugged will stop, and Walyro restores it automatically once that drive is connected again. If the file has genuinely gone, set the wallpaper again from its new location.
Check the file is still at the path you imported it from
Reconnect any external drive the video was stored on
Keep wallpaper videos in one folder you do not reorganize
4. Confirm it is actually a video wallpaper
It is worth ruling out the possibility that nothing is wrong and the wallpaper was never going to move. Apple's dynamic wallpapers are the usual source of confusion. They shift between a handful of still photographs as the day passes, which is a change measured in hours, not motion you can watch.
Aerial screen savers with Show as wallpaper turned on do move, but only until you interact with the Mac. Then they settle onto a still frame and stay there. If either of those is what you have set, a video wallpaper app is what you are looking for.
Still not moving
If none of the four applies, the problem is more likely the file or the app state than macOS. Try a different clip first: if a built-in starter video plays and yours does not, the encoding is the suspect, and re-exporting as H.264 usually settles it.
Beyond that, restarting the app clears any stuck playback state, and a Mac restart clears the rest. If it persists after that, send the details through support and include your macOS version and the format of the clip.
Test with a built-in starter video to isolate the file
Re-export an unusual codec as H.264 or HEVC
Restart Walyro, then the Mac
Confirm you are on macOS 14.0 or later

Common questions
Motion you can start and stop on purpose
Walyro keeps pause, resume, and per-display control in the menu bar, so a still wallpaper is always a choice rather than a mystery.
