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

Hi decided to revert back to High Sierra as Mojave started freezing and was slow.

I did not get one response from Apple regarding App Store not connecting.

Since that issue was affecting users during the beta stage, it should be still happening.

thanks! this worked for me. i tried to log out of iCloud account and back in, and didn't work, so i googled and found your tip. it worked and it was easy to do. i know upgrading the OS always will introduce random bugs, and this is quite a big one that Apple got wrong. 😟

Fantastic, and thank you. I have a comment about using terminal, I'm just not that versed in terminal (sorry, I swear im still an apple devotee) and i was able to accomplish these steps in finder. I was able drag and drop a copy of *.plst to desktop, removed it from the directory, then restarted worked like a charm. Thank you so much for the guidence.

BocaBoy,

I found this thread and hopefully you will still be able to give me the answer I need. I did what you said and now it works can you tell me how to TrustSettingsBackup.zip? I did number 1 again as well but do not see TrustSettingsBackup.zipanywere on my iMac? Were will I find this please show me were it is asap.

Thank you I am glad this worked for me too.

TrustSettingsBackup.zip should be in /Library/Security. It is only backed up so that it can be restored in the event something goes wrong. If you can't find it, don't worry. If you do find it, and everything is corrected with the App Store, you can delete it.

I thought it was fixed just got back on checked my apple store and went back to a blank screen so it did not work for me. I was happy for a little while. Oh well hope they release a fix for it. Also do not know were to look for this /Library/Security?

I sure hope they will fix it soon I just clicked on my name and still no apps showing that I purchased. Thnak you anyway for your help.I hope there is a Apple rep looking at all issues I know the high sierra you can give them feedback in the apple store aand there is none now?.

Library/Security are system folders under the root. I would tell you, as I did in my original post, to not attempt this fix if you're not comfortable working at the system level. There's way too much chance that you'll break something.

I feel pretty confident that this will be fixed in 12.14.1. If, however, you need it fixed faster, take it to the Genius Bar and have them run the commands for you.

Thanks for the info yes I am still having the problem after doing all you said in your past rsponse to another person. I did step by step and worked for a little while then went back on like 6-8 hours after and tried to get back on no luck having same issue I thought you had the fix for.

But do appreciate some insight to help fix my issue. Do you have any idea as to when next update would be?

Thank you once again we tried but no luck.

The only thing that worked for me was to do a search in my laptop for all app store apps. I found three. I deleted the two oldest ones and the remaining app store app began working right away.

Don't remember if I restarted the laptop or not.

I was only concerned about how many "app store apps" I had on my laptop. Not apps in general-just the app store app.

I don't know why I had three, but I did. They obviously interfered with other. And I then deleted two oldest ones and the remaining App store app works great

parrori1,

I did get my update but was in system preference is this how they are doing updates no no longer in the Apple Store? What did they update my Apple Store were my apps were working the first time but it did not fix that I logged into Apple store again and found no apps there. Why did they not include this with this long update like 45 minutes? They could of fixed the Apple store as well so it works but still does not work. Dies not show my apps only first time after restart and then shut down and was there as well but when I closed Apple store down they were gone again? I get them when I first log in when I shut down then rest of day they are gone? I need this fixed so if any Apple specialist is on here please see if this can be fixed as well with a update.

Thank you for all your help to all.

Re the updates, yes, you now go to the System Preference for app updates.

App store does have an update line, but it appears to show recent updates already added. App store is mainly for obtaining NEW apps I guess.

Updates to your existing apps are now found in the System Preferences icon that was formally used as the settings icon. That icon is still used as the iOS settings, just not the Mac.

As far as your new problems, you may want to call a Mac techie.

I tried to post this earlier but must have erased it:

Open the app store app. Look up at the top of the page and your will see "store".

Click on store and scroll down to the bottom of the dropdown and open "view my account"

You will see many of your apps if not all.

Click on the Apple logo, then click on the app store.

Lok at top of page, where it says "App Store", "Edit", "Store" "Window" and"Help" all in a row.

Click on Store icon and you will see a list of things:. Discover, search, work. Play. But look all the way down the Store open list and the next to last line says"View my account"

Click on view my account and then you will see apps.
