accountsd high cpu (300%)

Just had the same issue on my iMac. On the Activity Monitor, it was running System 25%, User 70% and Idle 5%, accountsd 300%, fan screeming. Chatted with Apple Support and they told me to run diagnostic, then shut down, start in Safe Mode. Then shut down again and start normally. And everything was fine!

Simply sign out your iCloud account until Apple solve this.

If you re sign-in the problem start again after 2 o 3 days.

Hope that helps.

Hi br0kenpixel,

It seems you're having trouble with usage from the Mail app and we can help.

Try starting to safe mode and see if you have the same issue:

Thanks for using the Apple Support Communities.

There seem to have been a lot of complaints about this problem: accountsd process 500% CPU in Catalina 10.15.7.

Some have reported installing the latest "Combo" update solved it: Download macOS Catalina 10.15.7 Combo Update.

"Safe Mode" may also be instructive, but the problem may return.
