I'm having trouble with the App Store since installing Mojave. The issue seems to have been addressed here, but since I'm new to this site, it won't allow to post there with follow-up questions. I'm not sure how to find/fix the "CFBundleVersion" issue described in that article. Furthermore, when I click Apple > App Store, it opens the current (broken) version, not an older version of the App Store. Any advice for someone who's a novice? Thank you!
Never mind, just figured out an easier way to resolve this:
- Spotlight > System Information.
- In the lefthand column, locate Software > Applications.
- Find "App Store" in the list. If there are two versions, click the older one and identify its location.
- Navigate to that location in Finder and confirm (via right click > Get Info) that it's the older version. Delete it.
I still have the same problem. I cannot delete the previous version and if I try to drag it to the trash it says "App Store cannot be modified or deleted as it's required by macOS" The old version is in the previous content folder. Any ideas?
