Verification Failed error when trying to Sign in to Apple ID on MacBookPro
Hi,
I am unable to log-in into apple ID on my Macbook Pro (16-inch, 2019), running macOS Big Sure Version 11.6.
I know this is not a wrong password issue because I am able to login in apple website.
The error i'm getting when trying to login to apple app store is "Verification Failed error".
I tried multiple solutions with no success:
https://discussions.apple.com/thread/251267296
* "Some people have solved this by going to System Preferences/Internet Accounts, selecting an iCloud account there, and signing in. You need to repeat this for each iCloud account."
- Indeed this time I got an SMS verification code, but afterwards I got the same "Verification Error"
https://discussions.apple.com/thread/251141112
* delete the device from appleid.apple.com page
* On the laptop open Keychain Access application - In the search bar type: icloud , delete com.apple.cloudd.deviceid.Production and iCloud Keychain Account Meta-data
Also, tried to reset default keychains in Keychain Access app, and restarted the laptop - all without any success.
Did some more investigation.
In my console after I get the Verification Error, I see in one of the entries:
Error Domain=com.apple.accounts Code=5
Google search have found https://developer.apple.com/forums/thread/6239
"Error Domain=com.apple.accounts Code=5 "A iCloud account already exists. Only a single iCloud account is allowed to be saved."
This Macbook is my laptop from work, hence I might not be the first one who uses it.
Please help,
Thanks.
MacBook Pro 16″, macOS 11.6
