Accountsd Mac cpu is high

accountsd process is eating 500% cpu and making macbook pro 15,1 useless after Catalina 10.15.7 update.

Even if you force this process to quit it comes back at ~500% CPU and make lots os apps to hang.


I have tried to disable iCloud Mail integration and other suggestions related to "accountsd" that fixed this issue in previous Catalina versions but nothing worked.


Any suggestions?

OK, so this worked for me.


  1. Go to "~/Library/Accounts"
  2. Rename Accounts4.sqlite to Accounts4.sqlite.backup


CPU immediately went back to normal. Didn't need to logout out of Apple ID, or restart. Just that file rename did it. Thread here - https://www.reddit.com/r/mac/comments/j05c8e/user_reports_show_that_macos_10157_clogs_up_the/

When I ask the system now it says it is fully up to date. So my question is why this update wasn't installed automatically?! Why do we have to search in Internet, to go until this page, to downscroll and finally to read your (helpfull) comment to be able to maybe solve this problem by downloading a "Combo Update" (that is btw taking ages to download) ??! This is crazy.

I'm having the same problem! seems that if you create another user session you can work it out in the meantime. The problem is that I need all the files on my main session.

Please help! I've tried many of the methods here and not working:

  • restarting keychain
  • deleting icould keychain
  • restarting by pressing alt + CMD + P + R
  • running both diagnostics on Activity Monitor
  • Running Disk Utility

Nothing...

Well, after installing the Combo update everything was fine. I even told my daughter to do the same on her MBA 2012 (same issue started today as well).


Then it started again after a whole day work.


I tried to disconnect the keychain and reconnect, what seems to make things worse: higher CPU load and I cannot complete the login to my Apple account (it asks to reconnect to enable all functionalities and stalls).

yes, i've installed onyx but.....you are installing updates from a company which should deliver proper updates....and not, a mess.....in this corona-tima, lot of people working from home can't call apple and tell them to fix this problem....even being here in a community without any official person from apple, telling: hey, we are working on it.....nothing...

After a couple of days with peaceful MacOS, today, out of nowhere, the accountsd process started the nightmare again.

I repeated the KeyChain on/off again, reboot, fine again.


I refuse to reinstall MacOS since this is such a radical and painful fix. A minor update shouldn't cause such damage to users and it seems, from the broad issue reported here, it could be something easy to detect if Apple really tested this update well.


Is Apple trying to turn MacOS into Windows with its crappy constant updates that brick systems and make users furious?

At least, windows machines are way cheaper than Apple.


This might also have something to do with iCloud being unresponsive during the local/remote data sync. Maybe accountsd is looping trying to sync forever and thus consuming this crazy amount of resources.


I don't know, they really need to take a look at this asap!


C'mon Apple!
