wallpapervideoextension in Sonoma uses lots of RAM and CPU

The "kill" technique does not really work with Sonoma 14.5, at least.

The process is restarted immediately. The launchd logs show it being respawned by WallpaperAgent.

Extreme measures to prevent the agent from running:

$ launchctl bootout gui/502/com.apple.wallpaper.agent

Boot-out failed: 150: Operation not permitted while System Integrity Protection is engaged

Did not work either. I did not try to go through the painful process of turning off SIP to see if that would allow the above as I have low confidence it will work.

I just noticed another post that talked about screen saver, I set the Start Screen Saver when inactive to never, and just have the display turn off after 10 mins. Let's see if that helps, will report back if this fixes the issue (note, it sometimes takes 2 or 3 days for this to show up...)

I solved my memory problem or, minimized it, on Sequoia by checking the mark on "show in all spaces" in the wallpaper settings window. While I have a ton of different photo folders, I can switch between them for all 'spaces' (I'd rather call them desktops; it's more intuitive and changes the perspective; Everything on that desktop should be dedicated to that desktop. Even with 8GB of memory, it seems to be running smoothly but I don't use any apps that didn't come with the OS.

Could it be that it is caused by dynamic wallpapers?, So just choose a color as wallpaper...

Same issue here. Didn't even use those silly "live" wallpapers and noticed a hot chassis on my 16" M1 Max. One of the reasons was WallpaperVideoExtension with >25% CPU usage for nothing. Please fix!

Apple OS quality became just unacceptable. Bugs and issues everywhere. Could they please stop their unpopular, annual releases and focus on QUALITY and PERFORMANCE first, again? Thanks!

I've noticed that the WallpaperVideoExtension is using upto 1GB of RAM and chewing up plenty of CPU under Sonoma. I have to use Activity Monitor every few hours to kill the process.

I'm not using any of the Apple video wallpapers/screen savers, and haven't d/l any of them.

Has anyone else seen this issue? Any ideas as to how to permanently kill the extension (set 'defaults' command in Terminal would be ideal).

Any help appreciated

Try uninstalling your "WallpaperVideoExtension" and compare your results.

if this is third party software

Look for a built-in or in-app uninstaller and use that.

If in doubt refer to the developers website; Support/Help/FAQ/known issues/compatibility /updates/uninstall:

Contact a third party vendor

I have this same issue: I am not using any of the Apple "Dynamic Wallpapers", but "WallpaperVideoExtension" burns tons of CPU time. Any advice on how to disable this from running would be much appreciated

-- its a total battery killer, and leads to the fan on my MBPro running quite often, even under otherwise light loads.

I'm noticing this issue more since 14.2... I understand while the wallpaper is animating it might take some resources but once it stops it shouldn't take much... I'm finding during normal operations it's just taking ~32% cpu all the time on my m3 max...

I'm having the same issue as all of the above. Fan runs almost continuously. When I kill 'wallpapervideoextension', everything goes back to normal. MacBook Air 13', 2020 running Somona 14.1.12. I'm like EJW Tas, that I find I have to re-force-close almost every time I start to work at the machine. I'll keep watching this thread. Thanks!

Same issue. It is really frustrating.... I've MacBook Pro 15 2019 i7(6 core) that i bought brand new from Apple... with just original/purchased software. Used only for work... and now all fans are running so loud, because i.e. /System/Library/ExtensionKit/Extensions/WallpaperVideoExtension.appex/Contents/MacOS/WallpaperVideoExtension and /System/Library/Frameworks/VideoToolbox.framework/Versions/A/XPCServices/VTDecoderXPCService.xpc/Contents/MacOS/VTDecoderXPCService processes eats so much CPU and RAM. By the way... I am CCNP and LPIC-3 certified... and I try to use this system for smooth QUIET hard work... and now I thinking if 10 yeard old Lenovo laptop is not the better and QUIETer way how to do my jobs.....

As our clients says: "Please fix it ASAP! How could this go to live? Do you have some PQA or testing? How you test this wallpaper extension before it goes live? We all pay for your devices thousands of $$$$...."

So please.... please fix it as soon as possible.
