Accountsd CPU usage high in macOS Catalina

I've got a 2.9 GHz 6-Core Intel Core i9 with 32 GB of RAM. Basically no limit on available resources. suggestd is at 7GB usage, Mail is doing fine at 680 MB usage. The issue is CPU. suggestd hovers around 70% to 100% and Mac Mail will bounce around. The latest beta seems to have improved things a little bit in Mail. Now they have to fix suggestd.

I'm back on Mojave. Catalina was way too buggy. I've had several issues, it was slow, mail was a pain in the brain, and shutting down my Mac took 1-3 minutes. I had the feeling I'm back on my 2010 MacBook white unibody with ssd and 8gb of ram but my 2010 MB it worked smoother than my MBP 15 2018 2,6Ghz i7 16gb 560x.

IMHO: the actual version of Catalina is Mac's Windows Vista.

ps. if you want do downgrade and you re running in to error -1008f make sure you delete your Mac in "find my Mac" "Find my iPhone" and logout of your Apple ID on your Mac. otherwise you've no chance to downgrade.

pps. I'm so happy to be back on Mojave it runs so smooth without any issues.

However, GMail cannot be the cause of that issue because I figured the same behaviour on my MacBook Pro 13" (2018) but certainly do not have a GMail Account. The high CPU load even prevents my battery from charging if plugged in :-o

Even though my Mac was plugged in the whole day when I take it home it would tell me that battery is too low to run the computer. Really annoying! I have to quit Mail to charge my Mac during work.

Adding to this- I have an iMac Pro and once I upgraded to Catalina accountsd hogs almost a gig of ram and my cpu spikes to 400% when mail is open. Making my 5k machine unusable.

I have 5 google accounts, 1 yahoo, 3 exchange, 1 imap, and 1 iCloud.

My work around is to disable the gmail accounts. That fixed it. I am using kiwi for my gmail accounts but this is a drag having to have 2 clients to check important emails.

FYI, the same accounts on my 2011 mbp running high Sierra work like a champ in mail. This is obviously a Catalina issue...

I tried disabling Gmail. That did not work. Then, I quit Mail, force-quit accountsd and started Mail again. Hours later CPU is back to normal. I can't believe it was this simple, and I know it did not work for some people. Hopefully it stay this way.

Is everyone on here using the Feedback Assistant to report these issues? I can't get Apple's attention and they have not fixed it in the latest beta. And I have a feeling unless everyone reports it they won't treat it with a high priority.

I went to checking "Manually" -- and for me, the high utilization and unusability has been solved. I thought the checking of mail setting only applied to POP3 accounts?

In my case, I have a bunch of now defunct POP3 accounts in Mail because I want to keep the messages available for archival purposes -- and I didn't really want to have to export/import them. Unchecking the "Enable this account" checkbox in Mail removes the appearance mailbox when I feel it should only make it so it doesn't check against it.

I'm quite certain that having a bunch of defunct POP3 accounts in Mail is triggering this in my case -- and setting the mail checking/polling to "Manually" isn't an issue for me.

After a day now, it only really quiets down after it checks for mail, sends, etc. But during any activity both Mail and accountsd will shoot up over 100%, 200%, ever 300%. So this did not really fix. It just makes it more manageable. Also, I did adjust Mail preference to check every minute as opposed to automatically.

Clearly, there is still a problem. It is also a memory leak. Before I did all of this accountsd was holding 1.7 GB of memory. After the force-quit it went down to about 15 MB and it is climbing again. Up to 280 MB already. Apple clearly needs to fix this, but they are too proud to do hot fixes. We are all probably stuck with this until Apple decides to include it in a regular update -- like with many other issues.

I'm having the same issue. Either its accountsd that goes nutty or the mail app process.

This is making my less than yr old MBPr with maxed specs, down to a 30 mins or less laptop.

I've changed my mailbox fetching to manual. It works for now. What the **** though. Why has OS X become such a bloated mess?

For now, I'm following this thread, waiting for a fix.

After days with this, the only way I can offer to deal with this is: quit Mail, open Activity Monitor, force quit accountsd, open Mail. This somehow clears it for a while. I also have Mail set to check/sync once a minute.

The real drag here is that most mail clients for power users (I have 11 accounts - exchange, imap, yahoo, gmail, iCloud) is that these clients get bloated fast.

Mail on my 2011mbp (and on my iMac Pro when it was running Mojave) is solid as a rock. How can this upgrade hobble such an awesome app?

Anyway, I've tried Outlook, Postbox, Airmail, Thunderbird, and more but only Spark seems to handle it's duties well. Still get crazy high memory usage but it sips on the cpu so you don't really notice it.

This is a colossal waste of time...

unchecked my icloud / .me account account quit mail restart - bingo - cpu now not egg frying territory... wtaf tho apples own mail service causing the problem? is it possible that icloud mail alone is the culprit anyone else concur? - btw im having issues with icloud docs / desktop sync - once a week maybe more have to turn off and on again or 'no access' wonder if theres a link?

catalina 10.15.1 MBP 15" 2017 16GB RAM 3.1 Quad Core

yep agreed on icloud dont trust it anymore for docs / desktop or mnotes - corrupted data all sorts weve had sisseus across the fleet here- email - when i said it worked - its 'better' not 100% great, still flipping between 60% and 200% - at least laptop fans have stopped and heho cant check my icloud email lol (ios only now i guess) sigh

For me the issue is when I activate my two Gmail accounts in Mail. Normally accountsd and Mail take 300% CPU for less than 30 seconds, when I make active both Google accounts randomly the CPU will go to 400% and the fan will start at maximum speed for very long periods of time, causing the entire machine being so slow that I need to close Mail to be able to work. When that happens, if I don't pay attention, and I close the lid it will drain the battery and the laptop overheat in my case... I tried multiple times deleting and recreating the accounts.

I have 5 Exchange, 1 iCloud and 2 Gmail accounts.

It is so bad for me that I'm trying to learn my way in Outlook now.

Thank you,
