iCloud doesn't work on MacOS 14 Sonoma

I tried to open iCloud from MacOS 14 Sonoma desktop, and was asked to allow it in the Settings.

I tried to toggle the switch on, and switched back to off after a few seconds.

After upgrading to MacOS 14 Sonoma, I no longer have access to documents stored on iCloud.

Mac mini, macOS 14.0

SOLUTION: Create a new profile on your machine with same perms (e.g. Admin), then login to that new profile and sign in to your iCloud profile using your Apple ID.


FIXED!


Senior tech at Apple indicated iCloud with some user profiles not syncing with Sonoma update and this is the work-around. Soon a 14.1 release will be provided to address this issue.

Dear apple team, you have to provide some working solution to accept the terms and conditions for this problem.

Me, as dev, have all the projects kept within icloud. Now realized, that i spent already 3 hours by trying find a solution and make things work.

If you'll count all developers, designers average hour cost to solve this issue, you'll get pretty big amount of money we spent.

Provide the solution and avoid such a cr*p being delivered on production.

My issue in notes is quite different. The app is just constantly showing the spinning wheel of updating sync. Any new notes do sync as they show up on iPad etc. I can type a new note of text but cannot type in any lists of hashtags or try and edit something already written. When trying to do that every grinds to a halt. Notes work normally on iPad so it is a Sonoma issue as everything was fine on MacBook before the update. It is seriously frustrating having to go to online iCloud to use the Notes. I have now had to start to type notes in Word as whilst not handy for the purpose at least it does not take 5 minutes to type in a word!

Apple doesn't seem to care. I've always used Apple products, but they have gone WAY downhill in the last few years especially with their customer service and fixing issues. If they can't guarantee that an update will work, they should allow users to downgrade to the previous version that worked, on all devices. My phone and macbook books don't work at all and books keep disappearing. I'm sure Apple doesn't even read these notes. Beyond frustrated.

Intel-based MBP. I am also able to sign into iCloud when I use a different profile on my updated-to-Sonoma (14.2) machine, but when I log back into my profile which has a LOT of stuff on it that I really do not care to migrate to a different profile, it still fails.


  1. I type in my appleid
  2. it prompts me for my apple password
  3. If I type it in wrong, it tell me it is wrong. If I type my password in correctly, it pauses a few second and then clears out my Apple id. This tells me that authentication to Apple id is working.

Can anyone tell me what are the particular cache files and such that I need to clear from my profile to reset this process so that it works?

Under the heading of: I'm not really sure? Maybe some developer[s] will say I am blowing smoke?


Thinking here that perhaps someone new in development, perhaps a contractor from overseas, may not understand the concept of event loops. Last time I debugged this it turned out 'he' had created multiple event loops with arbitrary jumps between one event loop and another. Some library may be damaged? Two crashes?

I don't know.


Application Specific Information:

BUG IN CLIENT OF LIBPLATFORM: os_unfair_lock is corrupt, or owner thread exited without unlocking

Abort Cause 35334


From the developers' forum back in ancient pre-SWIFT times.

The problem is resolved by switching to posix_spawn(). I stil haven't tested that on 10.6-10.11 yet though. My GCD version didn't work on older OS versions. My NSTask version started failing in 10.11 and didn't work at all in 10.12. That's why I switched to fork() to begin with. One out of 4 APIs is functional.
