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

MacBook Pro TouchBar and Touch ID, iOS 12

You're true MrJingles. I thought everything was working since I saw that I was connected to the Store. But trying to download any update or any new app is still not working :-(

The issue is old and I 've never seen Apple taking so long to fix a so huge bug...

I've tried everything presented as a solution on the web : deleting plist with the Terminal, reinstalling Mojave, changing certificates settings, changing DNS servers, etc, etc.... No result.

This solution worked for me too.


I signed out of iCloud in System Preferences. Kept all the copies in the system when prompted.

Restarted the system and signed in back again in iCloud in System Preferences

I was already signed in to the Mac App Store as it used to be before I was having this issues. However I found the installed apps were not recognised as installed.

Once system was restarted again the App Store correctly recognised the installed apps.

Try this from my post earlier in the thread that has worked for many others.


So, in my situation, I have a brand new MacBook Air Retina Display. It came brand new with Mojave 10.14.2 and at first boot up, I had the issue of not being able to Sign In to the Apple Store, but was able to sign into all other things like iCloud Drive and iTunes. So, my experience was not from an upgrade, but a brand new computer boot up; not sure if that is relevant or not.


I went thru this thread, any many others, and tried all of them to no avail. The deleting certian "com.apple.appstore", folders, messing with the Trust Settings folder, etc. All of them.

What did finally seem to work for me, which by the way is now after I have updated to Mojave 10.14.3 (I thought that might resolve the issue as many of you probably hoped too), was using AppCleaner.


I have version 3.5.

Launch App Cleaner and then drag and drop the "App Store.app" onto the window. If it gives you an error prompt, just open the App Cleaner Preferences and uncheck the box next to "Protect default OS X apps" and then try it again.

Once successful, it will show all of the components associated with the App Store.app.

Select all of them EXCEPT for the App Store.app and the folder /Library/Application Support. For me, they were the first two in the list. Do Not delete those.


After that, I restarted and actually performed an install of Mojave 10.14.3 over my existing one, but I did not erase or delete anything.

When I completed the installation and restarted, I was able to Sign in "FINALLY" to the App Store.


Someone may want to test whether a reinstall is needed after removing the files. I did not try that. I just went straight to the reinstallation. I hope this works for some of you.

Yeah I had the same problem where I couldn't get into the app store and sign in from a fresh new computer, a macbook pro 13 in. I was fiddling with the files but ended up just reinstalling mojave and now I'm able to sign in but still unable to download apps from the store or update existing ones. When I click "view information" under my account it says that it cannot connect to the app store even though other pages load so it's really bizarre.

I really thought your solution would work for me too, but unfortunately no, on multiple MBP Retina 13" that had been wiped and fresh installed with Mojave 10.14.3 for new deployments. And tried all the other solutions suggested in many other locations.

BUT, updating to the v5, and now v6, Betas of 10.14.4 has fixed it (didn't try any earlier betas, sorry, so can't speak for those).

SUCCESS!

Source of the problem was definitely a bug in the app itself, I reckon.

Cheers!
