NOT Fixed: accountsd using 400% CPU on MacOS Catalina 10.15.7 (19H2)

README.md

accountsd using 400% CPU on MacOS Catalina 10.15.7 (19H2)

TL;DR: Still open - see below.

This morning I woke up to some not-so-nice surprise - my 2018 MPB 13" would be kind of totally unusable. The accountsd process was stable at 400%, battery was going like ice-cream in the Sahara, and opening up LibreOffice was like a major achievement.

I did check the logs (that were growing at like 500 lines per second) and I saw a lot of lines at FAULT level:

fault	07:54:04.271342+0200	accountsd	Unentitled access by client 'CallHistoryPlugi' (selector: accountsWithAccountType:handler:)
fault	07:54:05.685220+0200	accountsd	Unentitled access by client 'com.apple.siri.e' (selector: accountsWithAccountType:handler:)

fault	07:55:26.732481+0200	accountsd	Unentitled access by client 'AddressBookManag' (selector: accountsWithAccountType:handler:)

To make a long story short, I looked at the full log where there was:

default	08:50:35.352204+0200	accountsd	[com.apple.calendar.accounts.notification] [Account ***MY@APPLEID**** (....) should have child account]

So I did go to system preferences -> Apple ID and removed my AppleID. I then added it back in, and everything went back to normal. Thanks Apple for three hours down the drain on a Sunday morning.

I am posting it here so if somebody else has the same issue, at least they can Google it.

I am not sure if this is related to Catalina 10.15.7 - I updated yesterday, so the coincidence is pretty suspicious.

Update 2020-09-28

Looks like the problem is back. I am now trying to stay logged off of Apple ID for now and see if this keeps the problem at bay. I cannot afford to use my Mac as an expensive fridge magnet and have work to do on it.

Update 2020-10-05

I'ts been a week, and still there is no definite workaround. From the many comments below, it looks like the only thing that actually works (and worked for me) is to be signed off of my Apple account. Yes, this allows me to work, but I'd say it's less than optimal. Deleting my Internet accounts and whatnot.... I need them. You know, the very reason I have a Mac is to have a hassle-free PC experience, where things just work and I can do billable activities instead of recompiling drivers.

Personally, I would not delete system databases that I'm not 100% sure what they are for, but YMMV.

Anybody knows if there is a filed bug in Apple for this issue? or how one is supposed to file one?

Update 2020-10-07

Apple Support contacted me on Twitter; I posted the issue and a link to this discussion and we'll see if there is an official suggestion/feedback/bug number.

Fixed after a week of problems.

it worked for my situation :

  1. signout from apple id
  2. reboot
  3. mkdir ~/Library/Accounts/Backup
  4. mv ~/Library/Accounts/*.sqlite* ~/Library/Accounts/Backup
  5. cp ~/Library/Accounts/VerifiedBackup/* ~/Library/Accounts/
  6. reboot

VerifedBackup contains the last working accounts that were created by the Apple update procedure before the problem.
If you don't have the VerifedBackup folder you can take the old sqlite files ( before the problem ) from time machine.

These following steps work for me:

  1. log out of Icloud
  2. reboot into safe mode
  3. log into Icloud
  4. reboot (if the pop up "Update Apple ID Settings" keep showing, ignore that and reboot)
  5. if that pop up keeps showing, enter the password one more time

Hope this works for you guys. I'll keep updating for the next few days :)

i need to log out and then log in again every time after I boot up the laptop. happened for me on both 10.15.6 as well as 10.15.7

I disabled email and find my mac under iCloud settings and it has behaved for two days now even with my Google accounts added again. Mail also disabled for the Google accounts. Maybe it's fixed for me, maybe it's not. Time will tell, but for others who still get the issue try disabling mail and see if that works.

Signing out of my Music Account (via the Music app), restarting my "mac" and signing in again solved this issue for me. I repeat this process everytime it starts again after a couple days. Note that I only had the "An ACAccountStore has no associated media type." console output.

Also for me, this was not an issue after updating to 10.15.7, I had the same problem on 10.15.6 too.

Looks like we have to just live with it. Probably Apple changed something somewhere to facilitate Big Sur, and that something isn’t compatibel with former versions. Chances are, they will advice users of these ‘older’ versions to either stop using iCloud (fine with me) or upgrade as quickly as possible to macOS 10.16 (Microsoft tactics and not fine with me). The reason I suspect this is because Apple is suspiciously quiet about this problem that sooner or later hits every Mac-user.

I bought an Imac 3 days ago, after updating to 10.15.7 this problem occurs to me too. I renamed the sqlite4. then i had to activate all my internet users. all runs well. after looking around i noticed i am not connected to icloud. First i get the same error (unknown error), when trying to log in. After a reboot i could log in to icloud. But after that accountsd is already high (400% cpu).

dont do this:
sudo -v ; killall -9 accountsd http://com.apple.iCloudHelper ; defaults delete MobileMeAccounts ; mkdir ~/Library/Accounts/Backup ; mv ~/Library/Accounts/.sqlite ~/Library/Accounts/Backup/ ; killall -9 accountsd http://com.apple.iCloudHelper ; sudo reboot

it is only temporarly, if you log in to icloud again problem exists.

seems we have to wait for a solution fix from apple. meanwhile everybody who wants to work normal should log out from icloud.

Update: Day 4, accountsd is still behaving normally after this procedure.
Every iCloud integration still working without problems.

this seems to work for me (day 2 without issue):

  1. Go to System Preferences
  2. Go to Apple-ID
  3. Click on iCloud
  4. Deactivate all programs you dont need (for me just Fotos, iCloud Drive, Calendar and Search my mac is left)
  5. Click on iCloud Options
  6. Deactivate everything instead of System Preferences (and what you may need)
  7. Done

Will keep you posted if the issue comes back or not.

Getting into Safe Mode while restarting by pressing shift fixing this issue temporarily for me at least... for about 5-10 restarts :D

Not temporary for me!!! Next reboot, login into icloud and the problem fix it.
Many days without problems 🤷🏼‍♂️

for a week i stayed away from icloud and after i logged into account today, the issue never reappeared. maybe apple fixed the thing on their end, but today CPU wasn’t hot even while syncing the libraries. hope it will stay that way.

After trying a lot from here I deactivated icloud drive only. System runs well. I activated it again, cpu runs high. So i deactivated it again. This is going well since 5 days now.

Signing out of the apple account resolved the problem for me too. As soon I'll login back the problem occurs again after some random time.

I had this exact same problem a few weeks ago and my temporal fix was just... not to shut down my MacBook but just send it to "sleep" for several weeks. Because after each restart I had the same problem and hat to manually fix it by killing the task accountsd. Initially I was on 10.5.6. A few days ago I updated to 10.5.7 and now I can restart without accountsd to fly through the roof.

Didn't try this but was about to follow these instructions if it happens again: https://mrmacintosh.com/catalina-10-15-7-update-accountsd-using-400-if-using-icloud-mail/
