Re: os x app store doesn't show anything

Have you attempted to sign out of the app store and then back in?

It start to behave like this after an OSX update.



I sign out and sign in... nothing happened.
I reset my "PRAM" ( command + option + P + R on computer start). Nothing happened.

Any solution???
