Photos Agent is taking up all my CPU
A few days ago I noticed a process that is constantly running. It takes up a lot of my CPU and therefore my fan is running high after just opening Safari or doing some multitasking. My battery is at 60% after just an hour.
The Activitymonitor shows the Photos-Agent running all the time at around 90% CPU. At first I thought the photos app was just downloading a few photos and processing them. But this is going on for some days now and it's not getting better.
I attached screenshots from the Activitymonitor showing the process and its details.
It this a problem with the latest MacOS Update? I have around 5500 pictures in my photo library.
