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

I wanted to double check my system for the "Previous Content' folder a poster posted several posts above, just to make sure I didn't have any left over stuff, even though my App store is working. The issue is, they didn't leave the path to where the folder was, and Google didn't bring back any results of a folder with that name regarding macOS.

Where was your Previous folder located with the other version of the App Store? It's not in my Applications folder, or root of the hard drive, or any other typical place I've searched.I initiated the command to create the locate database, so I'll use that in a bit, but if you could give any feedback on where you found the mentioned folder, would be appreciated.

Thanks.

Thanks, I guess my upgrade got cleaned up correctly. I didn't have this folder. I also only have one copy of the Mac App Store. Everything's been a cool breeze here, ever since I cleaned up the App Store, and reset it to defaults by removing the files I mentioned in an earlier post.

One other note, while I use the App Store for some of my items, I really prefer to buy directly from the developer when possible, usually makes things easier to manage, and they are free to include features apple's App Store policies prohibit.

I seem to have the same issue. Here the two lines from system.log. Maybe somebody can make sense out of it...

Sep 30 19:09:37 iMac App Store[794]: DEPRECATED USE in libdispatch client: dispatch source activated with no event handler set; set a breakpoint on _dispatch_bug_deprecated to debug

Sep 30 19:10:01 iMac App Store[794]: objc[794]: Class ITNSImage is implemented in both /System/Library/Frameworks/iTunesLibrary.framework/Versions/A/iTunesLibrary (0x7fff8f217568) and /System/Library/CoreServices/SetupAssistantPlugins/iTunes.icdplugin/Contents/Ma cOS/iTunes (0x10f22e7c8). One of the two will be used. Which one is undefined.

I have this problem too, not only with the App Store but also with Apple Books (book store). Same issue, cannot log out and cannot open the book store ( internet connection required). I do not have problems with the iTunes Store. More of you who reconize this also?

I should have asked this earlier, but those of you having these issues with Mojave and the App Store, etc are you having any issues with iOS 12, on your same connection? Just curious if there is any sore of connection.

OK, that's good. I wasn't having issues on either of my iOS devices. As you know I fixed my glitches on Mojave. Was more thinking since iOS, TVOS, and macOS share some of the same internals, that it could be a bug there. Since not, sounds like it's related to the Macs more specifically.

When Mojave works, it feels like a very nice ride. Hope Apple speaks up soon.

One of the hard things I find about helping on forums is you usually don't know the people directly, and can't handle the setups for myself. So I only have what the people say to go on. In this case though it sounds like Apple knows about this issue now, and it doesn't seem to be a specific group of people affected with any specific setup circumstances.

This isn't a question directly in line with the topic of this thread, but, is there a way to contact Mods here?

I was reading that they are the only ones that can change a username, and I would like this one changed to one of my nicknames I use on a more consistent basis. I created this years ago, and I don't even remember why I picked this name.

Same problem here.

I create a new admin account with my Apple ID, same problem.

When I run the App Store application, I just see "Cannot connect the App Store" with a button "retry". What's really strange is when I click on the Store menu, I get nothing at all.

At this point in time, I think we have tried everything possible except a clean install. So all we can do is wait for Apple to come up with an answer. I for one won't drop this if I don't hear soon. This is my work computer, and in some form it is creating a problem for me. For one, I got into trouble for creating another account. This network I am on is a secure network, and a secure location. So I had to remove the second account. At least I didn't lose my administrator account.

I can copy the Security file but I stupid out when it came to the other steps.

I don't know where to go to begin the cd part.

Also, is that command performed on the original account or the alias?

Anyway, I here declare my stupidity.

Open Terminal (Applications/Utilities) and cut and paste each line, one at a time, into it. Hit Enter. If you're prompted for your password, it's asking for the password you log on to your Mac with, which should have Administrator access.

Ohhhhh k. Still out. Every time I posted a line and then hit Enter, it would just repeat my name plus MacBook Pro.

I do appreciate all you that tried to help me. This failure by me is not on any of you. It's all mine.

OK lets do it this way.

1. After the first line was entered, did the line below that ask for password? If yes great and enter next line there will be no more prompts other than your MacBook Pro line. Then enter the next line also no prompts other than MacBook Pro. If all lines entered reboot. All should work. If you didn't get the prompt for password get back to us.

this was really helpful, both app\book stores are back to normal. appreciate that! just wondering apple allows this issue for such a long time with no official response 😟 , also any impact when remove this file?

Im giving up. This is what happens to me whenever I hit enter. Also when i enter password it doesn't take i.e. not posted
