Today I restarted my iMac 2019 and suddenly it was very slow. Starting Chrome or Photoshop took more than a minute while normally this takes a few seconds. Also unhiding the dock or starting a new finder window took for ages. It felt like my old iMac when the HDD began to fail. I also got an error message from Creative Cloud: "Adobe Creative Cloud, needed to resolve this problem, is missing or damaged".
The only thing I could think of that had changed, was the internet connection went offline due to a malfunction with my provider.
I ran Etrecheck and after a long time it said "A process is using a large percentage of your CPU." The process was mentioned in the report as "Other processes 116.57 % (?) Activity monitor showed a very high CPU time for meta data server related processes. But there weren't any processes using a high amount of CPU at the time of checking.
Then I used Disk Utility in Recovery Modus but the drive was ok. Back in MacOS everything was still going very slow. Than suddenly the internet connection came back and all the problems were gone! This was great, but my iMac should function normally when there is no internet. So I unplugged the router, restarted, but everything was still working great. Then I did a Apple Diagnostic test and all Hardware was functioning ok.
Does anyone know what this could have been?
