Mac keeps saying update Apple ID settings

Had the same issue. Not sure the issue is a corrupt keychain, as much as it is a "not yet connected" keychain.

Here's how I solved it:

• In System Preferences, tap Apple ID
• In the SysPrefs Apple ID sidebar, tap iCloud
• In the main pane, scroll down to Keychain
• If the Keychain checkbox is already checked, stop reading, this won't help, sorry
• Click the Keychain checkbox.

That last step prompted me to enter my iPhone (yes iPhone) pass code. Did that, all is well. That's what makes me think it was an issue verifying/connecting all the keychains.

Nice suggestion! I opened the finder, selected "home," and then navigated to /Library/Keychains/. Within that directory is another directory named with a unique key. I changed the name of that directory by appending "_save". Reboot. Problem solved! Thanks for that tip.

It is a pain to do but I took the following steps to finally resolve the issue:

1. Go to System Preferences --> iCloud
2. Logout of iCloud
3. Reboot system.
4. Login back into iCloud.

This seems to have fixed my issue

Worked a treat. Thank you, Glenn.

Had this issue and perpetual "New iCloud Terms and Conditions" warning since updating to Catalina!

Re-enabling iCloud Keychain fixed the "Update Apple ID Settings"

Still not been able to get rid of the perennial T&Cs error though despite how many times I accept!

I had the same problem. It’s a problem with a corrupt keychain. I sync keychain via iCloud, so I moved the contents of the keychain folder to a new folder, then rebooted and I was able to successfully log back into iCloud.

I just signed out of iCloud using the button on the bottom and then signed in again. That took care of this issue on two different Macs for me.

I just signed out of iCloud and signed back in. That seemed to do the trick.

THANK YOU! This resolved the problem for me. At least so far, so good. Cheers!

Renaming the UID folder in /library/keychain worked for me! Since I use iCloud Drive for my documents folder (huge) this was much easier and faster than even signing out and back in to iCloud.

When I rebooted I had to enter my iCloud password, local machine, password, and iPhone pin code.

Thank you!

Same issue 2012 MacBook Air 13". Keychain fix didn't work; it kept unticking itself and asking for login again. Signing out of iCloud and back in seems to have worked. Thanks to all for the tips.

Since people mentioned being really oddly asked for their phone lock code it occurred to me to look at my phone and I discovered that my iPhone also had a Keychain toggle-off glitch in addition to the obvious one on my iMac. And the iPhone was even less cooperative than the iMac at pretending to fix it. It would spin up - then present no new screens and just pretend nothing had happened and stay off.

What I did - and which has seemingly been stable for the past hour - was first fix the iPhone by signing out of iCloud and then back in. A big hassle. Lots of requests for passwords. Had to reactivate the credit cards. Ugh. But Keychain did toggle on.

Then I tried toggling on Keychain on the iMac. After a few attempts, I got it to stay toggled - which, as we know, is not the real challenge, since after a few minutes, it may switch itself off again.

So I took the insane risk of toggling it off myself, and going through that whole procedure.

Then I toggled it back on. And weirdly, did indeed get asked for my phone lock code.

Now both both phone and computer are displaying normal Keychains and have for the past hour.

No guarantee this will last. Any unnecessary magical-thinking steps in this and mistaking good luck for causation? Oh, you bet!

Odd side issue - the iPad never had a problem.

Question of the day: if the iPhone is supposed to be so amazingly secure why and how is Apple asking for its lock code to be sent around outside the device?

Truly all this seems so much like a really elaborate phishing charade to collect all codes that I hesitated to continue. And yet it dug so deeply into the devices and into a very secure app like Keychain and so many knowledgable people were experiencing it I decided it had to be a really, really strangely broken Apple issue. Indeed, I don't think I've seen any other half as weird.

Did try Apple Support first. The agent was very nice, decided he needed escalated advice, apologized many times that things seemed to be really...busy...at Apple Central. And after a half hour or so, I gave up. One wonders how many broken keychains and other updating issues Apple is trying to cope with today.

I had this problem too when using my primary iCloud account and I tried the usual options to resolve it. Then I remembered that I also have a secondary iCloud account which had been deactivated. I re-activated that account, agreeing to the new Terms & Conditions, and hey presto the issue on my primary account was immediately resolved.

Suggest deleting all contents of the directory Keychains/ -- this worked for me.

The directions here of changing the name of the directory within the directory is nonspecific since there are two directories. Also, this didn't fix my problem until I deleted all contents in the Keychains/ directory, image below:
