Mac App Store not working on macOS Mojave 10.14 Beta 1 (18A293u)

Question

Does anyone else have issues while trying to use new App Store on macOS? I can log in but I can't download or update any app.

Sometimes it asks me to change App Store country to one linked with logged in Apple ID (Croatia) and when I try to change it App Store gives me error ‘Cannot connect’.

Restarting Mac didn't helped.

How to solve this issue?

Answer 1

With latest beta 2 update 10.14 Beta (18A314h) issue is resolved.

1. Update macOS to latest 10.14 Beta (18A314h)
2. Open App Store
3. Click on Store -> Sign Out in menu
4. Quit App Store
5. Open App Store again
6. Sign in

After this I could update apps and initiate new downloads.

Answer 2

macOS Mojave is currently in early beta phases. The stable public release is due in fall.

Such unintended behaviours may appear due to the nature of the release.
