Mac OS 15 use extreme much RAM for Wallpaper SWAP

i have seen today that my RAM Usage was 80%.

Why do you think that's a problem? Modern operating systems will allocate memory dynamically. Memory not used is memory wasted.

Look at Memory Pressure in the Activity Monitor to get an idea of how your Mac is performing. If it's in the green, it's fine. I'm currently using 15.32 out of 16 GB (95%). My memory pressure is green.

Making the image folder "com.apple.wallpaper.extension.image" read only seems to have fixed the issue for me (has only been a few hrs). Also deleted all the ".PNG " image files that were there even though they could not be viewed.

I see now the swap grow and shrink due to my usage whereas before it would grow every few seconds then kill the computer. Keep in mind when I started through ssh the parent folder "com.apple.wallpaper.caches" is not visible even through sudo so it's faster to do it local and go open custom folder and go from there to the path.

Thank you for the help.

Sorry but the Terms " Task manager exist from the Taskbar " are Terms for Microsoft Windows

As the Owner of this question has not mentioned Crashes

This issue you describe seems to be unique to your computer

Running 3 different machines all with macOS 15.0.1 Sequoia - can not say any of the machines exhibit such behaviours

Side note I don't suggest deleting the folder as it will just get recreated and continue the problem. Making it RO prevents altering and causing the problem. You can see the modification date of the folder change as images are placed into it.

That's not a major issue, especially if it doesn't last long. Are you having any actual problems with your Mac? Is it running slowly? Are things crashing? Why are you monitoring the RAM usage? Unless your investigating an issue, there's not usually a reason to do that.

Last year I remember there was a folder where from a normal photo size 4 MB for exampe the system was made a png file which 15-25 MB per photo. For what?

That has nothing to do with RAM usage.

And two the same think again. But this time I cant change something.

No idea what you're trying to say there.

I believe you're missing the point of the conversation. When your mac starts crashing it's why you would load and start to leave open the process view and see the memory pressure it's literally why the tool exist and why it's placed in the Dock. It's why Task manager exist from the Taskbar. Maybe similar or not to the OP , on my end my computer crashes at random times sometimes after an hour other times I can go 2-3 hrs but it's guaranteed to crash once the swap reaches ~45GB. So keeping an eye on when it's going to happen is important.

Spending time to explain to someone about normal memory pressure or usage of a computer like they are nubes does not help with the actual concern / problem. When I am using my Vision pro I also have a permanent resource monitor open in a floating window somewhere. "Tech enthusiast are a thing".

The OP never mentioned crashing. Or, in fact, anything other then RAM usage. Perhaps they will provide additional information in response to my question. If and when they do, I will adjust my answers accordingly. Until then, I will answer based on the information actually provided by the OP, not surmises from a third party.
