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

I found a solution that worked for me. It took me two steps, and all credit to BocaBoy in this thread: Re: Mojave installation fails: duplicate App Stores, can't sign in with Apple ID (Macbook Pro, Late 2016)


  1. Disable System Integrity Protection:
    1. Reboot the computer into restore mode (press command-R during startup)
    2. Select Terminal from the Utilities... menu
    3. Enter csrutil disable and press return
    4. Restart
  2. Back up and archive the folder in /Library/Security/Trust Settings before deleting them through Terminal. I'll copy BocaBoy's instructions here for you all:


OK, I just spoke with Apple engineering and they gave me a fix for this. It worked for me and it may work for you. You must know how to use Terminal and access hidden directories with Finder in the root of your drive.


First, make SURE that you've backed up the directory /Library/Security/Trust Settings. Copy it on your Desktop or Downloads directory, or wherever you'll be able to access it.


1. Again, back up the user certificate trust settings files described above. Then, remove them with the following commands, entering your administrator password when prompted:


cd "/Library/Security"

sudo ditto -ck "Trust Settings" TrustSettingsBackup.zip

cd "/Library/Security/Trust Settings"

sudo rm *.plist


2. Attempt to sign into the App Store.


This didn't work for me until I restarted at which point I was able to log in and see all of my accumulated updates. If you're not comfortable working at the system level, DON'T do this. If you are, this may fix your problem. It did for me.


Once you're sure that you've got the App Store working, you can delete the TrustSettingsBackup.zip file as well as the backup of the Trust Settings directory.

3. Reenable System Integrity Protection by repeating step 1 but using the command csrutil enable.


After I modified the Trust Settings directory, I was able to reboot and connect to the App Store and Books Store.


Good luck, everyone!

I guess when I go into the app it will say update I am so confused now. I hope that is what will happen. Thanks anyway for your help but if I had screen shots it would be easier to do but will just keep it open all day until I log off computer for the night. I guess I have to live with it I would think there are more people with this issue I am surprised no one else is saying thye have a problem and not fix to it.


Thank you all for your help

This is what I posted earlier to show why yo need to see the tip top of the screen.:


"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 buttonand 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."

If I open them there is no problem .Its like once I quit the apple store and then go back into the store then they are gone.Go figure there has to be a setting on/off ot is it the new update to it. I wish there was someone in this group or a apple specialist on here would see what I am having a problem with but you have been great but just getting aggravated with this issue now. I regret doing the update I cannot believe I am the only one with this issue.


But thank you for all you help you have provided to me I know your trying to figure it out to and do appreciate it.


Thank you

parrori1,

I guess you do have a few years on me. I am glad you will look into it a lttle more for me maybe you have more info than me since I am younger (just kidding) 🙂.

Thank you very much for your help and have a good weekend I am in the east coast of CT and have to change all of my clocks 1 hour back and I hate this getting dark too early. I love DST.

Look forward to hearing from you again my friend for some help.

I managed to fix this on my mac while waiting to be transferred to senior support. App store, Itunes, Safari, none of the apple apps were working on my mac running Mojave. However, Firefox still worked. I installed Chrome just to see if it also worked, and it didn't connect...BUT it's error page suggested I check Proxies in Advanced Network Settings, and uncheck any that were checked. The SOCKS proxy was checked, so I unchecked it, hit Apply and everything started working again! I have no idea why this worked, but it did. Good luck.

ACASMARIA,

Mine still does not work I think apple should have a fix for this but have not heard anything about it yet. Hopefully they will do a update when they see all the problems with apple store not displaying my apps. No matter what I do it does not work everyone on here tried to help but no luck yet maybe someone has the final fix.

Thank you to all that can help us.

Have a great day

I have had so much trouble with iTunes lately. I run 3 airports, 1 is my wifi the other 2 run speakers It has worked so well for the past 6 years through iTunes. Great system. Now AirPlay 2 nothing but problems.

I have been working with Apple support for weeks but still problems. I love the setup but when it doesn’t work F...k. Sonos is looking good.

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