Clear AppStore cookies and locally stored data How to clear my OSX 10.8 AppStore cookies and locally stored data?

I also heard that there's a debug mode in AppStore, How can I enable it?
You can enable the Debug menu by typing the following into Terminal:

defaults write com.apple.appstore ShowDebugMenu -bool true


You can then clear the cookies using the Clear Cookies option in the Debug menu.

In addition, you can reset the application using the Reset Application option.



You can disable the Debug menu using the following:

defaults write com.apple.appstore ShowDebugMenu -bool false
