Overview: After upgrading to macOS Mojave we have noticed many Mojave users are having difficulty login to the App Store, either they are not able to login to the App Store or receives an error “Cannot Connect to App Store”. Today in this post we will troubleshoot the issue with the App Store and get this fixed.
Let’s Start with Few Practical Scenarios
Scenario 1: Cannot connect to App Store since Mojave
Just updated to Mojave and dark mode on our iMac 2017 27″. I can see all my iCloud settings in System Preferences > iCloud > Account Details. In the App Store, however, I cannot sign in, meaning it asks me for my credentials, but after I hit enter nothing changes and I am still not signed in. In Books I am still signed in (acc. to the menu “Store”), but I cannot see my purchases, because it cannot access the book store. I deleted the files in /var/db/crls, reset all the Apple Root Certificates and even ran this terminal command defaults delete com.apple.appstore.commerce. I rebooted several times, … but I still cannot sign in at the App Store, iTunes and Photos work and I can see my Library and Photo Stream, respectively. Any help or hint? Thank you!

Scenario 2: After upgrade to MacOS Mojave, I cannot log in or connect to the 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 shows “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

Scenario 3: Cannot Connect to App Store since the upgrade
I upgraded to Mojave and I have had issues App Store. When I open it says I need to sign in, then will not let me do so. It says that an unexpected error occurred when signing in. I have deleted my certificates and restarted. I also changed my keychain to trust and that did not work.
