Last week, my iMac informed me that there was a problem with my iCloud connection. My password was not working. I reset it. It works on my phone and iPad, but I am getting an "Unknown Error" on my iMac when I attempt to sign in to iCloud. Has anyone seen this?
iMac, iOS 11.2.6
You realize that there are no Apple representatives here, right? We're all users like yourself. If you want to report problems to Apple use this link: https://www.apple.com/feedback/macos.html
Download and run Etrecheck. Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.
Try booting into Safe Mode, Mac OS X: Starting up in Safe Mode, and logging in from there.
Yes, rebooting in Safe Mode and logging in to iCloud worked. Give it a shot!
I was having the same issue when I updated my Macbook 2014 to Sierra. It also was the same time when I updated my password for iCloud. I had to reset my keychains to clear and start everything from scratch on logins. That seemed to do it.
I have this problem as well. So far the only way to connect is to reboot the computer.
That's what ended up working.
After so many years with Windows and being told the answer was to reboot, Apple has spoiled me. It is rare that I have had to do a restart as a solution.
But it worked.
Have you tried a restart?
We deleted everything; sign off my icloud account; delete all my keychains; update my Mac software; it worked fine for a few days and then i had to do it all over again. And some things i couldn’t even recover from Icloud. So frustr
Let me be more specific. I haven't changed my Apple ID or password in the past few months. Everything works fine on the iMac until it doesn't. No pattern as to why, but I may get email one minute and the next it says I need to sign into my iCloud account. When I enter the correct password it rejects it saying I am using the wrong password. If I restart my computer the problem clears up ... until it happens again. Using System Preferences does not solve the problem. I'm not sure where the glitch in the system is, but there surely seems to be one. (I have not problem connecting with my phone or iPad using the same password.)
My issue is the same. No problem on my iPad or iPhone, just the iMac. (I even went so far as to create a new password which was very cumbersome.) But rebooting does not solve the problem for me. I had to get help from Support, which resolved the problem for about two days. And then it happened again.
In sort, no resolution yet.
If you haven't done so already, try resetting the printing system.
I didn't change the password recently, but a MBP computer message told me 'trouble signing into iCloud" so I go and reenter the password. The password is rejected three times, even though same password works with the iPhone. I noticed this a few days and hours/day later I saw a calendar item had at last synched. It fixes itself it seems, but this is making me seriously mixed up on my appointments. Randomly my MacBookPro is disconnected from iCloud, not by my choosing. Currently disconnected. 😟
So has anyone heard from Apple support? Is it worth it to go to the nearest Apple Genius Bar? I don't want to have to lug my iMac all the way to an Apple Store 30 miles away if it will just keep happening. I don't even want to use iCloud or Keychain....
Same problem for me and my Mac will not print documents on my printer although it is connected, Wifi and Ethernet, and recognizes it but says the printer has an error. All of this started at the same time after the latest big update.
