Cannot sign into App Store OSX Mojave

:'( Well this is incredibly frustrating. I should probably be happy that this is the first real issue I've had with an Apple product in 20 years, but UGH!!!!

Nothing changed after resetting all warnings for buying and downloading.

Are you running any sort of Anti-virus app?

Do you have another user set up on the Mac that you can log into? If so, log out of iCloud on your User ID, and log out of the App Store there as well. Then, under the new user, sign into your iCloud account and in into the App Store with your Apple ID. See if the updates for your ID show up there, and try updating one of them.

Close your App Store and try to run the following command:

defaults write com.apple.appstore.commerce Storefront -string "$(defaults read com.apple.appstore.commerce Storefront | sed s/,8/,13/)"

It solved my problem.

I installed the latest update of Mojave; 10.14.4, and it seems to have fixed the AppStore sign-in problem for me.

Previously I could not sign-in to the AppStore to get updates, even though iCloud etc. was working fine. I can sign-in and see updates/downloads as normal now.

OK, so I have one additional option I can offer. First, close the App Store App to stop the perpetual download, then open your iTunes app, click on Account>View My Account and provide your password when prompted. Once your Account Information screen displays, scroll down to the bottom of the screen, and click on the Reset button next to "Reset All Warnings for Buying and Downloading". Go back and open the App store and see if you are now able to download successfully.

I was having exactly the same problem, and your advice (logging out of iCloud and then logging back in) solved the problem. thanks.

I THINK that worked. I signed out of iCloud, then back in. I then opened the App Store and I was already signed in. I'm attempting to download one of five updates now. Waiting to see if it works. I'll update here once it either works or fails.

Also, yes, I've been successfully signed into iTunes Store the entire time.

What do you see at the bottom of the dropdown when you click on Store in the top menu?

I have this same issue. New Mac mini, running macOS Mojave Version 10.14.3. I have followed all Apple recommendations to resolve the issue but I'm still unable to sign-in.

1. When I open App Store I see that I'm not signed in (bottom left).
2. I click sign in (bottom left).
3. Sign in windows appears with my Apple ID preloaded.
4. I enter my password and click Sign in.
5. A daisy wheel spins for a few seconds next to my Apple ID before the Sign in window animates up out of view without signing me in. No error messages, etc.

Thank you in advance for your help. It's super frustrating.

Is that where you were trying to do the sign in from? Have you tried restarting your Mac? Any other troubleshooting you have already done?

I've tried signing in from the menu (screenshot above) as well as the Sign in button at bottom left in the App Store itself. I've also tried all steps recommended from Apple including restarting. I even tried a fresh install of the OS. Everything else works with this new Mac mini including iTunes.

(thank you so much for your continued help!)

(you're welcome 😁)....

If you are not using iCloud Photos (because you don't want to have them all re-downloading) , try signing out of iCloud in System Preferences. Then see if you can sign into the App store without being signed into iCloud (I'm not running Mojave, so I can't check that, but it is very possible that you will not be able to sign it in until you sign back into iCloud). If you need to sign back into iCloud before proceeding, then do that. Then try signing into the App Store again to see if the sign in will complete.

And just curious, are you signed in successfully to the iTunes Store?

Hi RaccoonLand. When open Finder, then select the menu item Finder / Preferences, what am I supposed to select all of? I also don't see "make new folder from selected items" after clicking on the gear wheel. Thank you for your help!

Since you have not told us what the issue is, we can hardly be of any help. Why can't you simply sign in the normal way? What is the issue? What happens when you try?
