Extension process Apple ID (4589) exited

I am not sure that I lost access to iCloud, but I was getting a message like that in System Settings with a fresh install of Sonoma--no data carried over--and I was getting a popup saying that I had to agree to a new iCloud agreement, but I just kept getting similar errors in System Settings. What seemed to help was signing out of my AppleID on the Mac and then signing in again. This also asked me for my phone password, and the Mac Password, so maybe that's part what was bugging the software. I don't know.

I also have the same problem on my MacBook after update to Sonoma. I have tried logging out of the Apple ID on my Mac but when I click Apple ID or Internet Accounts in System Settings it comes up blank or I get the "extension process exited..." error message. I have also tried removing my MacBook from the account under Apple ID/Devices settings from a browser but that does not have any effect. Finally, I tried setting up a new account on my MacBook, with the same Apple ID, which solved the issue for half a day but the problem re-occurred. I have two other accounts on the same MacBook with different Apple IDs and those are fine so the problem appears to be specific to the Apple ID. I have 3 other Apple devices (1 MacMini and 2 iPads) and I am able to access my Apple Id from System Settings on those devices without any problems. My Photos app on my MacBook updates so it is still connected to my Apple ID but I just cannot access Apple ID from System Settings....totally stumped!

Although my profile photo was still visible, I tried this anyway and sadly it did not work. I entered the directory service command to delete profile pic then removed my MacBook from my trusted devices. As expected it asked me to sign in to iCloud again but when I selected the iCloud preference pane I got the "extension process Apple ID exited" message again. The only thing that has worked is to setup a new user but the problem recurred eventually which suggests it may not necessarily be a problem with my profile? I have two other Mac's without the same problem...

Signing out of my Apple ID and back in as described by @meswa fixed this error for me

Mcmlvi, sorry to hear. That means it’s not a 14.3 fix, unless we have different variations. Keep posting, and perhaps ask Apple support to open an engineering case.

I think it is Sonoma issue. I also have the same issue on my MacBook after update to Sonoma.

I've tried many solutions suggested on this page but I still have the same error code after another.

Other functions like calendar, iMessage, memo, etc are working and synchronizing well, but ONLY photo album synchronization is not working.

I am using icloud for two another devices, iPhone and iPad, but it has no issue.

Please update and resolve this issue, APPLE!

Thanks for the detailed notes. Two points I would add

1. After upgrading my Macbook Air M1 to 14.2.1, iCloud profile disappeared completely from Settings. My iCloud account still appears under Internet Accounts but when I click it, I get the error message "Extension process...". However my mac is still syncing fine...photos, calendar etc.
2. I am logged into the same iCloud account on two iPads, a Mac mini M1 and Macbook Air M2 without any problems.

I'm surprised. In my case, I didn't do factory reset, but I have the error on a brand new Mac, right from the factory. Will update when I have anything more.

That's when the Sr. Advisor says, "OK, we are going get a load of data from your machine and submit it to engineering. We'll capture your system logs, screen movies of the error, and other data, send to Engineering. The standard is they respond in two business days. I'll call you back then."

mcmlvi - As you, I had no success with any of the solutions suggested in this discussion thread. As you, error occurs on different MacOS versions.

I have an "Engineering Ticket" open and have, with Apple Advisor, made extensive data captures showing the problem on a completely clean Mac.

Will post here when/if I get more info to share.

I booted into recovery, ran a disk check on the volume and then reinstalled MacOs but sadly it did not have any effect and the problem still persists. It does however suggest that the problem lies in a corrupted file tied to my user name/profile and that one possible solution would be to reformat the disk and reinstall MacOs. Obviously it's a nuclear option and I am not recommending it but curious if any one has gone through the pain of trying it...?

I was chatting and getting phone support for a total of 4+ hours. They managed to get me back into my MacBook but I had to sign out of my iPhone and log into the account that was connected to my MacBook. In addition to this I was told that I had to use my iPhone to do it. Can't remember all of the steps because it was literally trial and error (bless the representatives that had to help me because they remained patient while they too were trying to figure out trick after trick, hack after hack to get back into my computer. Anyway, after disconnecting the call, thinking that the problem was resolved, the Terms and Conditions message popped up in my MacBook settings, I clicked on it thinking that I would be allowed to accept it, but here we were again..it gave me the Settings Error Message!!! I say this to say, even when the problem appeared to be fixed it created other problems on my computer and MacBook, smh. If I knew that one update would cause so much strain I would've left it alone until my computer absolutely needed it because this is too much!!

It sounds like there may be multiple issues with the same symptom. My Mac is still shown as a trusted device under my Apple ID in iCloud and my photos etc all sync properly to the Mac. However I cannot access my Apple ID under Settings. I get the extension process error message. I have tried removing the Mac from trusted devices and re-adding etc but still no luck. I have two other macs updated to 14.1.2 and neither has this issue.

This issue is still not resolved 2 months later. I just updated to Sonoma 14.2.1 hoping it might help but quite the opposite. The Apple ID panel has now completely disappeared from Settings but my mac continues to sync with my iCloud account - e.g. I can see new photos take on my iPhone etc. When I select Internet Accounts in setting, my iCloud account is visible but as soon as I click it, I get the "Extension process Apple ID exited" error message. I checked the system logs and noticed that I can consistently generate a crash report - JetsamEvent - every time I try to open iCloud account in settings. So from what little knowledge I have about macs it seems that opening iCloud settings is somehow creating memory pressure that forces the process to quit?
