Hi,

I am on the latest Developer Beta.

two days ago I recognized hearing the fans of my M3 iMac while doing almost nothing and it was very hot on the chin, mostly in the middle.

I regocognized two procecess going crazy and it happenend several times since then. I am doing nothing in Photos while that happens also there isn't anything syncing because no other device is online. I even disabled photos in iCloud because of that. The only thing preventing it to happen again is renaming the Photos Library, so the App thinks there isn't any.

I don't know what is causing this. I just was looking for Videos on YouTube and doing nothing else. Only one Tab open in the browser. Closing ever app doesn't help.

I don't know how to stop it. I always force quit the processes and then it's mostly coming back and I have to reboot at least twice and then it's coming back again the next day but always after the Mac is in use for half a day.

I also disabled Spotlight for anything because it's also consuming much cpu power while this happens.

Here is a screenshot of how it looks like at the moment, it doesn't really change, the numbers are jumping up and down, but total load always is staying over 70% and up to 100% while just writing this message.

I couldn't stop it with Activity Monitor and rebooting. I removed the file-extension from Photos Library (it's just a folder now) and after that had to force quit some processes several times until they don't came back at least with those high numbers. Now I am down to less than 25% CPU load and none of those processes are included in the Top 5 anymore.

Any idea what could cause this?

So, it came back even without having a ".photoslibrary" file on my Mac and iCloud photos disabled.

This time I was again doing almost nothing, just watching a video in IINA player.

So the cause cannot really be the Photos app, if there isn't anything in it and if it's asking to create a new library or choosing a file when I open it.

I gave the Photos Library folder the extension back and reactivated iCloud sync. Even that first sync where all photos were compared to the ones in iCloud didn't produce any high CPU load of that photolibraryd process.

Seems the only thing what helps is force quitting all those high CPU consuming processes for a few times and then it's gone until about 24 hours later.

It's always this coreduetd, corespotlightd, imagent, IMDPerstenceAgent and PTVAM in addition, but photoslibraryd is always on top.

Seems I have to look, what all those things are for.
