To enable the menu, close the Mac App Store if it’s open. Then, open Terminal (search for it in Spotlight) and enter in the following:
defaults write com.apple.appstore ShowDebugMenu -bool true
Now, after entering the code, make sure to open the Mac App Store again and then check in your menu bar. You should see a “debug” option.
Go ahead and enable it and you can fool around with the settings.
Nothing groundbreaking here but it’s a neat little trick for those of you who are like me and like exploring and unlocking every hidden feature from software. 🙂
If you ever want the debug menu to go away, just make sure to close the Mac App Store, open terminal, and type in this code:
defaults write com.apple.appstore ShowDebugMenu -bool false
