I've reported this as FB7397666.
I have seen the same issue. I sync eight email accounts, five Exchange, two Gmail, one iCloud. It seems to spike when I close the lid after being working with the email, expecting the MacBookPro will go to sleep. Hours later I find the laptop extremly hot in my case and the fun at full speed. At that moment I wake it up, CPU is between 200% and 350%.
It's a doozie of a bug.
For me the workaround is to have BOTH a sleep time and wake time scheduled in Energy saver. If I disable either one the logging returns.
that hlped me . Does the same job for me .
Big big thanks, Ross! This workaround solved my problem.
I was on the edge to downgrade to Sierra!
I have the same problem, and the temporary workaround worked for me. THX a lot.
Same here, thanks for the workaround that fixed the issue
The same problem! This hack is working! Thank you!
But shame on you apple! Fix it! It's realy awfull bug
Thanks a lot for this trick, it works despite I don't understand why. I 'm ready to live with that unknown reason!
My MacBook Pro 16" is silent now!
I bought my Mac 1 month ago and the fans were working almost 90% of the time!
I searched for hardware issues, and also pointed the guilt on my usb-c adapters for some time.
When the Mac was on a clean install of Catalina 15.2, the issue disappeared.
So I believe the cause is a bug of powerd combined with the setup coming from my previous installations.
My previous Mac was a MacBook Pro from 2012 and I had updated the OS since.
