Mojave App Store is only showing Updates tab

Installed Mojave yesterday - everything is fine except the App Store doesn't show Discover or any of the other tabs - it only shows Updates - see screen grab. The search function works so it's connected fine. I've tried deleting all caches, etc

Solution 1:

I have found the solution (and origin) to this problem. Thanks @charles for giving me the insight.

The problem occurs because the new Mac App Store app CFBundleVersion is marked as 1 so if you have any copy of the old Mac App Store (which had CFBundleVersion over 459) in the system, macOS will think is the most recent version and will try to use it on the background.

This is why if you go the the Apple Logo > App Store… it tries to open the old version.

Deleting the old app bundle from the system resolves the problem.

Solution 2:

I am seeing the same issue. Not really an answer but more diagnostic info:

• MBPro early 2015, 13-inch Retina
• Tried resetting PRAM
• Tried starting up in safe mode
• Tried deselecting all the boxes in the advanced tab of the software update preferences
• Tried launching it from terminal (don't know why I thought that would work)
• Ran
• disk first aid
• Created a new user account and I could see all the tabs in that account.

Because the test user was vanilla, I am guessing there is something booting up in the primary account that is causing a conflict. Primary account is an admin and test account is a standard user without admin privileges.
