Mac App Store Download does not start on fresh installed Lion I needed to reinstall Mac OS X, so my plan was to format the drive, install OS X Lion (since I have the USB stick here) and then update to Mavericks.
Sounds simple, yet I have a problem: The Mavericks download does not start! I logged into the App Store and clicked on Load, and it says that the download is in progress.

But: Nothing happens. I do not get a progress bar in the Purchased Menu and the Icon in Launchpad only says it is Loading but the progress bar there does not change.
I tried another already purchased app and it did not work either!

I deleted everything in the App Store download folder - no success
Try resetting the Mac App Store.


Enable the debug menu and restart the Mac App Store.

defaults write com.apple.appstore ShowDebugMenu -bool true

Choose the Reset Application option.
