I upgraded from Mac OS Mavericks 10.9.5 to Mac OS Yosemite 10.10.1 and have issues with Mac App Store.

If I search for an item, I get results, but if I click a result, I get a blank page, whatever the app's page I want to see.

As you can see, the classic app background doesn't even appear.

I do not experience this issue on a fresh install of Yosemite in another mac, so I did bought my app on the other mac and used the search results's menu to install it on the right one, but that's quite tricky.

I tried to reboot, to reset the PRAM and other stuffs I seen over the internet, but didn't found any good answer.

Try resetting the Mac App Store.

  1. Enable the debug menu and restart the Mac App Store.

    defaults write com.apple.appstore ShowDebugMenu -bool true
  2. Choose the Reset Application option and restart the Mac App Store.

  • Thank you, I didn't know about this feature, nice. Anyway, after a reset, I still get a blank page.
