Cataline accountsd problem!

I haven't had the out of control CPU usage and I don't use Firefox, but every day or two accountsd grows to more than 2GB which really puts a damper on the performance of everything—even with 16GB of RAM on a brand new 2019 MacBook.

I'd expect closing mail, calendar, and other apps that use internet accounts would allow it to recover on its own, but the only way to recover from the memory leak seems to be rebooting.

☹️

It sounds like you've got something that's using accountsd and triggering it for heavy CPU utilization.

Cannot resolve it too. I temporarily logged off from my Apple ID and the problem disappeared.

Waiting for the update from Apple, maybe it will resolve this bug.

Before the Catalina my MacBook flying in the Air. After - I can cook on it.

I have the accountsd problem, but it seems to be triggered by Apple Mail being open. BOTH my 2013 iMac and my 2017 MBP have the problem. Like you, I'm hoping a new update comes out to resolve the issue - having to work with mail using my iPhone because both computers are essentially useless with Apple Mail open is getting old.

Yeah, I'd hate to have to switch back to Outlook for everything (mail and calendar anyway), but…it takes about 36 hours for accountsd to hit 2GB of memory utilization and then intermittently (probably during syncs) it consumes so much CPU that Activity Monitor reports it as 300% utilization or more. 🥺

Switched back to Outlook all week. No problems from accountsd; it stayed under 300MB for almost a week without a reboot. 😢 I hate having calendar and mail in the same app, so I'm going to see if using Outlook for mail with the Mac calendar open will start leaking resources in accountsd. 🤞🏼 I kinda got used to the Mac mail app, so I do hope Apple fixes it (and announces the fix so I know I can switch back).

I spent a couple of hours on the phone with Apple Support on Friday, and wasn't able to resolve the problem. Based on the above helpful feedback, I loaded all my email addresses and calendars to Outlook, and have been using Outlook today with no issues. I guess I'll just use Outlook for now and wait for Apple to come out with a fix before switching back to Apple Mail and Calendar.

Still using Outlook for mail, but I turned the Apple calendar back on a couple days ago. It still causes bloating in accountsd, just at a slower rate than mail. 😢 It's up around half a gig now, and I'll probably be forced to reboot in a couple more days. Hope somebody at Apple's working on a fix for their process model…

The Apple calendar bloats accountsd more slowly than Mail, but it still does over time. I haven't rebooted in a week, and accountsd has doubled in size to 1GB now while Calendar has been open. It's better than every other day while using Mail, but…

I'm still using Outlook for email, but probably going to have to reboot soon. I miss Mail.

Just logout from the account of my wife, added another one for me and logged in on apple. No issue 😏

Try to add new account on macos before reinstalling the os itself.

I don't know what triggers it, or I'd've already fixed my own 2GB accountsd problem. 🥺 Sorry.

Did you try a clean install of Catalina?
