MacOS - frequent "security settings verification required" "confirm Mac password" and "Some iCloud data isn't syncing" messages

I have the same problem:

MacOS 15/15.0.1- frequent "security settings verification required" and "Some iCloud data isn't syncing" messages

no way found can solve the problem!

I've been having this for almost a year now or longer, I can't remember exactly when it began. It went from a weekly to daily occurrence and now if I try entering my password the notification simply doesn't go away at all.

Would be nice to find a fix for this that doesn't involve deleting and re-downloading all iCloud data if possible. Oddly enough I have no issues accessing iCloud data at all so I've just taken to ignoring the notification, though it is an annoyance.

I also have this problem. No matter how many times I take the requested action, nothing happens. The same request for action never goes away. I’m concerned that I might lose data because the computer thinks no action has been initiated. I’m sure there is some way to fix this. I just haven’t found it.

All Apple Account Suggestions stopped once I did the following:

1) deleted or download all unnecessary files or photos on iCloud account.

2) Sign out of iCloud on my Mac(mini) and then followed instruction prompt to back up recommended contacts, settings, and passwords.

Once the above criterion were completed all Apple Account Suggestions prompts disappeared. (for now fingers crossed ). I believe that this issue is primarily related to the introduction of the password app in the SequoiaOS and secondly to a user's iCloud account limit for the syncing aspect. And thirdly Apple may have updated their security protocols in Sequoia. What I don't understand is why no patch was developed for this issue by Apple.

Solved for me by logging out of iCloud and logging back in on my mac. I was then able to resolve these messages. This was post Sequoia update.

The same—and a huge point of frustration. I use many Apple computers between work and home. It only appears on my home Mac Mini (M1). It started months, if not a year, ago for the "Security Setting Verification Required." Since 15, it's now prompting for iCloud Data. Based on my review of photos and files, I see no sync issues but cannot get rid of the prompt.

A log or more information on what's not syncing would be a great addition to a generic message.

Are you also having trouble with signing into the Security Settings Verification Required suggestion? Just started having this issue this on my Macmini 2018 which I just update to the new SequoiaOS.

Cheers mate,

That works for me!

Thank you very much

Just logged out....on both phone and mac....and still have issue.....only on my mac.
