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 To do this enter the following command in the terminal.
defaults write 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.

If you want to  turn the Mac App Store debug menu back off:

defaults write ShowDebugMenu -boolean NO
