Mac App Store Debug Menu
By Richard Mallion
The Mac App Store has a debug menu which is disabled by default. You can enable the debug menu, by enabling the ShowDebugMenu key in com.apple.appstore. To do this enter the following command in the terminal.
defaults write com.apple.appstore ShowDebugMenu -boolean YES
Once enabled, there are a number of options to show the folder where apps download, enable logging, clear cookies and reset the Mac App Store.
defaults write com.apple.appstore ShowDebugMenu -boolean NO
