Can't change iCloud settings.
Recently I'm having troubles to activate any functionality on iCloud on System Preferences - any checkbox I check is unchecked after few seconds. On console log I see lots of this errors:
[AOSAccounts] : [ACAccount+iCloudAccount] : -[ACAccount(iCloudAccount) icaCloudKitToken] - icaCloudKitToken cannot be returned as account is still not vetted!
What does it mean and how can I have iCloud fully functioning on my iMac with HighSierra?
Thank you
iMac (27-inch, Late 2012), macOS High Sierra (10.13.6)
