Mac App store broken in Mojave

My only solution at this time is to kill the "appstoreagent" in Activity Monitor after open the APP Store App. After this you can download Updates or new APPs.

You must do this after any System restart or sometimes after close the App Store APP.

I hope Apple fixe this bug quick.

I am having the same problem on all three of my Macs.

I've tried all these and have had no luck.

I've restarted

I've deleted the temp folder

I've killed appstoreagent

I've logged out and logged in

I just get the spinning nothing downloading…

Any other suggestions?

I have the same problem with the appstore in mojave. Killing the appstore agent in the activity monitor and at the same time sometime closing out the appstore and restarting it works all the time but it is not the actual solution but more like a crutch. I have to keep repeating this process every time. I have also killed plists etc nothing seems to be a permanent fix. I also noticed I don't get any notices for updates. I am guessing that part is not working either. Often the appstore does not list what I have downloaded and what was not downloaded I get the cloud download symbol for every software downloaded or not. This is usually resolved by restarting the app store. Does anyone have a permanent fix? Also this may be a different problem or not. When I have my backup disk with time machine hooked up the app store will show updates and will update the apps in the time machine. Is this normal?

I have an external drive with Mojave before the last Security and safari update and it downloads fine.

I think the problem might be in one of them. Not sure I'am thinking of calling apple about this.

Happy to have found this thread. I'm experiencing this problem, too. I've tried killing the appstoreagent. If the App Store is still running, it seems that the agent is restarted; if not, the next time the app is started, so is the agent.

Question: To which temp folder are you referring?

This worked for me. WOW

Did you force quit the "appstoreagent" in Activity Monitor after you open the APP Store App?

that's how I did it

Apple seems to have fixed the problem, currently it works on all my Mojave Macs without killing "appstoreagent".
