When Illustrator 2021 or Photoshop 2021 is open, Adobe processes use high CPU

Since I upgraded my two Macs to the new Illustrator 2021 (v.25) and Photoshop 2021 (v.22.0.1), I notice that there is almost always one or more Adobe helper programs running at high CPU usage when I have either Illustrator or Photoshop open even when I am not using them. I see this on both my iMac running Mojave and my MacBook running Catalina. At the moment, 'AdobeIPCBroker' is using ~200% CPU and 'CCXProcess' is using 120% CPU on my iMac. I also see 'Adobe Illustrator 2021' using about 100% CPU on my iMac Pro, even though I have no files open in Illustrator, only the app open. This machine has 8 cores, so these processes are only using about half the cores, but I can hear the fans running because the load is constant.

I can see my 'AdobeIPCBroker' has run up 143 hours of CPU time in a few days, so this has been happening for a while. I also see the Apple 'cprefsd' program running sometimes, but I don't know if that is related.

Hi Ashutosh,

 

Thanks for the suggestion. These computers are managed by my employer, so I am not supposed to create extra user accounts.

 

Thanks,

++Eric

I installed the Illustrator update v 25.0.1 today and it seems to be working much better. I don't see all those helper processes running now.

This problem seemed to be better for a while after I installed the Illustrator v25.0.1 update and the Photoshop v22.1 update, but now I see it again almost immediately if I open a document in Illustrator and another document in Photoshop (both opened with Bridge) on my Mojave Mac. Here is a screenshot of my Activity Monitor on the iMac Pro as an example, which has 8 cores but is down to 25% idle with all these Adobe processes running and using 6 cores.

An additional follow-up: I installed the Illustrator 25.1 update several weeks ago, and this CPU usage problem has not returned. It seems that Adobe fixed it in the v.25.1 release.
