Mac keeps saying update Apple ID settings

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.

Ok, this actually didn’t work, it only worked for a while. I had to sign out of iCloud and back in again to finally fix the issue. When I did, it asked me for the passcode of my lPad Pro. Note everything seems to be working like it should.

Me too...it was working for a day and then it popped up again. However, at that point, when I went to iCloud, it prompted me for the passcode of my iPad as well. I haven't had it since.

Again...it's something that I can't believe didn't come up during testing. Even a message to simply say "we are logging you out of iCloud during the update process - you will need to log in once we're done" would have sufficed.

>> Truly all this seems so much like a really elaborate phishing charade to collect all codes that I hesitated to continue.

This wasn't something I had considered but that's a very valid point. If one wanted to phish for codes, this might be precisely the way to do it - and NOW, after this debacle, Apple has kind of offered a roadmap on how to do it.

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.

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!

If this is an iCloud issue with the keychain then to reset iCloud account you really should log out of iCloud on ALL devices at the same time and then sign back in.

Start with your Mac and work your way down in size. (That's not really necessary it just appeals to my sense of order.) But do start with the Mac.

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:

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.

When attempting to sign out, should I select to “keep a copy of iCloud data on this Mac before signing out”?

Same issue here. Can't setup keychain with iCloud.

Thanks Glenn Gibson that took care of my system also!!!

Thanks, that worked for me too!

Thanks, Glenn…it also worked for me.

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.
