Accountsd process using huge amounts of CPU and memory

The Accountsd process uses huge amounts of CPU and memory that makes my laptop almost unworkable. This happens when I'm not connected to the internet and the Mail app is open. This is a big problem as I need to access emails when on the move and often I won't have internet (e.g. on a train or plane or a place without wifi)


This became a problem after installing Catalina and it took me a while to figure out the issue. When connected to the internet, there is no problem at all.


I have a MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports) with 2.7 GHz Quad-Core Intel Core i7 and 16 GB 2133 MHz LPDDR3.


Any ideas?

I've had this problem on a 2017 15.4" MacBook Pro and 2019 16" MacBook Pro both running the latest version of Catalina and it happens regardless of whether or not I'm connected to the Internet. I manage A BUNCH of e-mail accounts using Apple's Mail.app.


1 iCloud

3 Exchange/Office 365

8 Gmail

1 Yahoo!

1 IMAP/SMTP


I did a little experimenting and have found that accountsd and Mail.app behave "normally" when I'm ONLY using it to manage my iCloud account. I have Outlook from Office 365 managing my Exchange/Office 365 accounts. I use Thunderbird to manage my GMAIL, Yahoo! and IMAP/SMTP accounts. Everything EXCEPT my iCloud account was removed from the System Preferences -> Internet Accounts pane. I've been running this way for the last five days and performance has been great.


In this time I have NEVER seen either Thunderbird or Outlook 365 consume > 100% CPU. Their "Memory" usage seems to stay around 512 MB (Thunderbird) and 741 MB (Outlook). My fan NEVER runs.


Today, I added one Office 365 account back to Mail.app (I'm still using Outlook 365) and since doing that, performance seems to be OK.

Hey!


I really would like to know if you really have the same problem or just a similar one related to accountsd. I mean… I was reading the post on the site you shared and I don't have any of those things. I don't have a gosht keychain and the computer work well and the accountsd has a normal behavior if you don't have exchange mail account enabled in mail and no connection.


I just disabled my exchange mail —just the mail— and everything work well even with mail open and no connection. At least in my case the problem is pretty specific to Exchange mail accounts on Mail app on Catalina.


What is going on, at least in my opinion is, mail just enters in a loop when you have a exchange account and no connection and try to connect to the server all the time.

I also did not have a ghost keychain. Also, it seems like the problem is gone as soon as I disable a certain exchange account. And yes, I also was able to reproduce it on a new user.


I think we have exactly the same problem.


The problem just was temporarily resolved when I was applying the actions suggested in the blog post's last amendment. As far as I remember I deleted the account details in the keychain and removed and re-added the mail accounts.

Yeah… and annoying… you can't imagine how difficult is to get English support when you are not in an English speaking country. I'm from Spain, but I live in Finland. Everything this is a pain in the *** additionally to the normal level of pain in the ***.


Localization of services is evil.

I have this problem too since I migrated from GSuite to Office 365. I did not have this problem (as far as I recall) when I only had one Office 365 account set up, only since I have 2 of them.

Running Catalina 10.15.4. Accountsd jumps to 160 % CPU use very often, despite being online.


The others who have this issue: Do you also have 2-factor authentication enabled with Exchange / Office 365? Would be cool to know if that‘s something that can be ruled out as a problem, would not want to revert back to not using it.


Also: I (often) use S/MIME, sign all my messages and receive a fair amount of encrypted messages. This is only true for the account that was migrated from GSuite, the other one (which does not seem to have this problem) does not contain signed/encrypted emails. What about the others with the problem?


I currently don‘t have a fix for the problem and am considering moving the Outlook 365 accounts to the Outlook for Mac app. :-/.
