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

Your welcome but did you understand what I was looking at? What do you mean you mashed it? Never heard of that before I guess i am older than most of yoou all I am 58. Maybe after you read it you will be able to help me then. Any others want to try to help looking for a fix but you have been awesome and know you will come thru for the help I need. Do you think there will be a update for a fix in this Apple Store issue and how can I find it on internet?

Thank you all for all your help which I really need to be fixed. There used to be a coffee cup app that was like a timer and would keep the IMac on so you could do something and it will still be on screen its like the new one I found but like the older app better. tHIS IS WHAT i am using since I cannot find mine,

Any help we be great from anyone.

Thank you all for your help

Hi frank_the_snake

Here are my screen shots. The last screenshot is showing the current App Store 3.0 highlighted because I I have since deleted the old App Store version 1xx and can not highlight that for you but hopefully if you scroll around in there you will find it and be able to delete it.

Amyskis,

When you look at my screen shot can you tell me the one to delete or what section its in?I am still confused on this seems easy enough maybe you can help me a little more. Can I not just go to this, then to system report?

I have a similar problem since a few days. I cannot connect to the App Store.

Also in system preferences (Mojave) the text says: Unable to check for updates.

In the App Store:

The store menu item is no longer working (no drop down menu) and on the left there is not even text!

(see below).

I exhausted all possibilities I found here or on the internet. (Refreshing certificates, deleting various stuff, even restoring from time machine: versions that worked previously do apparently no longer work.) Even with a new account or with safe boot the same problem.

In console there is now a number of errors (see list of events when starting app store, filtered for "app store" in the error log)

Please let me know, if someone has a novel idea:

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.

Hi,

I am also facing the same issue. I am using a 2018 Macbook Pro and after I upgraded to Mojave the App Store doesn't connect. I have tried all the steps mentioned here- If you can't connect to the iTunes Store, iBooks Store, or App Store - Apple Support

Nothing helps. Still figuring out the solution.

Thanks

I've tried all of the proposed solutions in this thread to no avail. Out of desperation I re-read the Apple advice at If you can't connect to the iTunes Store, iBooks Store, or App Store - Apple Support. When I got to the part about checking any third party firewalls and network filters I realized I had little snitch running. When I turned little snitch network filtering off, lo and behold, the app store came right up.

I found under unapproved rules a rule to deny outbound connection to the app store because the code signature was invalid. I also noticed that unlike the example in the apple support document, my /var/db/crls directory only contained one file names crlcache2.db. So I may either have the wrong certificate file or I am missing the correct one. But clearly the issues has something to do with an include code signature on my machine.

Hope this helps someone who knows more than I do formulate a solution.

Same problem here. Nothing can be done. All the advanced ways of doing it (i.e. certification in keychain and deleting of files in /var/db/clrs etc has been done. No use.

Anyone solved this yet?

How to take a screenshot on your Mac - Apple Support

I was experiencing this issue until this morning and now it seems to have been resolved. I'm not sure if it was fixed by something I did or if it got fixed on Apple's end, but here are the steps I followed just in case:

• Open Keychain Access app
• Select "System Roots" keychain and "Certificates" category
• Find the "Apple Root CA" entry
• Open the certificate, expand "Trust", switch to "Never Trust", close the certificate
• Re-open the certificate, expand "Trust", switch to "Use System Defaults", close the certificate
• Do the above two steps for every "Apple Root CA" entry, "Apple Root Certificate Authority", and "Developer ID Certification Authority" certificate

Essentially, this is resetting the Trust settings for any Apple-related certificates. After I did this, I was able to view my account in the App Store app instead of seeing the "Cannot Connect to App Store" message. I was also able to add my Apple Pay card to the system again (this was not working before).

I'm still not able to install apps from the App Store, but that may be a separate issue.

I just spent four hours trying to figure out this **** problem and tried several things.

Here is the easy answer:

Never mind, just figured out an easier way to resolve this:

1. Spotlight > System Information.
2. In the lefthand column, locate Software > Applications.
3. Find "App Store" in the list. If there are two versions, click the older one and identify its location.
4. Navigate to that location in Finder and confirm (via right click > Get Info) that it's the older version. Delete it.

Voila!

Had a same issue and here's what helped to me. Not sure which of these steps was the actual solution, I suspect it was one of the first two:

• remove and re-add any Apple Wallet credit cards from System Preferences -> Settings
• uncheck "Find my mac" in System Preferences > iCloud and check it back
• kill all processes using Activity monitor that start with "store..."
• remove following files/folders (make a backup):

~/Library/Preferences/com.apple.appstore*

~/Library/Cookies/com.apple.appstore.binarycookies

~/Library/Caches/com.apple.apstore*

After that, restart.

Update

Navigating to /var/db/crls and deleting all of the files in there, followed by rebooting my machine, restored the ability to update and install apps in the App Store.
