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)
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!
Funny enough: after trying to repair it all ways that are described on that thread without any solution, I waited. At some point the problems basically went away by themselves. Not sure, whether s.th. was changed on apple side or (I suppose this was it) a change to the company network was made; perhaps their authentification requires special ports. I simply do not know, but it is weird and extremely annoying that there are no meaningful error messages, or logs.
I also tried everything else (deleting caches folders, trustfile, updates, different internet connection, logging with different account, logging in on guest account) but this one really worked! I first was afraid I would delete something essential and then would have to reinstall everything.
Thanks!
Thank you Checkyorself289. This is the only fix that worked for me. Before the fix, the App Store would show that I am signed in but I could not see my purchased apps and and account information. It had the error "Cannot connect to App Store". I followed your instructions and after reboot, I tried to log in to the App Store but still could not connect. So I signed out and signed back in to the iCloud and reopened the App Store and bam! I can already see my purchased apps and account info!
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.
Still not working. Geez, the apple online chat spend all my afternoon to do those tests, and told me that this is not a issue submitting to dev because "others are not having such issue". See how many folks are here?
After trying everything, this solution worked for me!
Only difference: I did not have to reinstall Mojave - just rebooted my iMac and then started AppStore and went directly to Login.
AppCleaner is really a very good tool, used it for years.
Thanks, this is the same error and the same problem signing out and signing back in. Like you, none of the troubleshooting steps worked.
Already tried all of the steps presented in the guide. Non helped. The problem is still there. Running on MacBook Air mid 12. Latest Mojave official release.
Thanks for these steps! I'm glad they worked for you.
I tried these and it didn't fix the problem on my Macbook Pro but will update if I find a solution.
I sent the threads up the Support chain—hopefully we'll get an answer and a fix.
I also have the same issue.
Same here, cannot use App Store....
And if you try to buy something...
MacOS Mojave, iMac 2012 late.
Same exact issue here.
I tried a bunch of different stuff last night but no luck.
Hoping one of you gets lucky with support and can let us all know!
I have the exact same issue, I enter my account information but it never logs me in.
No response from Apple Support as of this afternoon. Will update as soon as I hear a response.
After upgrade to MacOS Mojave, I cannot login or connect to App Store.
