After upgrade to MacOS Mojave, I cannot login or connect to App Store.

I am using the latest MacBook Pro 2018 version. After upgrade to MacOS Mojave, I cannot sign out, login App Store or View my account. It always show "Cannot Connect to App Store". I also upgrade my iMac to MacOS Mojave, my iMac does not have this issue.


How can I fix this issue on my 2018 MacBook Pro?


Thank you

I experienced this problem after a fresh install of Mojave on a MBP (15"/2016).

After running through a lot of troubleshooting tips from this thread nothing helped.

My solution was to log out of iCloud in system preferences, reboot and then log in to iCloud again.

Beforehand (during the fresh install of Mojave) I deactivated iCloud Drive, Stocks app and some other stuff I don't need in the iCloud system preferences. I think this was what caused the problem.
