accountsd

I have the exact same problem since Catalina 10.15.7. Did not have it in 10.15.6.

The workaround is to log out of your Apple ID. Go to System Preferences -> Apple ID -> Overview -> Sign Out...

Hopefully Apple can fix this soon in a patch for Catalina, or the upcoming Big Sur.

As you said it makes Safari, Finder and Spotlight completely unusable due to hangs.

Hello, there is no solution to this problem currently, it is the "Accountsd" process which uses all the CPU. I have had this problem for a few days on my iMac and on my macbook pro. Many forums are talking about this problem and we are waiting for a solution (bugfix) from Apple

further information, it appears that the domain com.apple.accounts does not allow access:

CallHistoryPluginHelper "Error returned from daemon: Error Domain=com.apple.accounts Code=9"

erreur

accountsd "Client <private> is not allowed to access accounts of type <private>."

panne

accountsd Unentitled access by client 'CallHistoryPlugi' (selector: accountsWithAccountType:handler:)

erreur

CallHistoryPluginHelper "Error returned from daemon: Error Domain=com.apple.accounts Code=9"

accountsd uses over 700% CPU on brand new MacBookPro 16 with Catalina 10.15.7 and none of the described solutions worked so far. MacBook is currently useless. Have to work with the home office iMac until Apple solves this...

As an intermediate solution, we can try this in the terminal.

It ends the process on "accountsd", delete MobileMeAccounts, makes a backup of the "Accounts" library and then ends with a reboot. You will also have to reconnect to iCloud but it worked for me

sudo -v ; killall -9 accountsd com.apple.iCloudHelper ; defaults delete MobileMeAccounts ;

mkdir ~/Library/Accounts/Backup; mv ~/Library/Accounts/*.sqlite* ~/Library/Accounts/Backup/ ;

killall -9 accountsd com.apple.iCloudHelper ; sudo reboot

I have a brand new apple powerbook as well (3 weeks old) running on Catalina 10.15.7 - same thing. This morning I logged out apple-id and then logged back on after restart. I thought it worked ok for some hours. But now its impossible to work again..

I had the same problem and there was no way, I had tried almost everything and, after thinking about it a lot, as it was a synchronization problem with iCloud, I realized that the IOS 14.0.1 update had recently come out, and I had updated the iPhone, but not the iPad. I have updated it and, for now, in a few days I have not had a problem again. I hope it can serve you.

Just log out of Apple ID as a workaround. It works. Try it.

Thanks, I already did that without success.
