We’re not sure why the average Mac App Store user would want to do this, but we couldn’t resist to post about the Debug menu Apple left behind in the Mac App Store. Discovered by Daniel Jalkut of Red Sweater earlier today, enabling the menu is fairly easy: you just need to quit the Mac App Store, open Terminal and write:

defaults write com.apple.appstore ShowDebugMenu -bool true

Then relaunch the Mac App Store. To revert back to a Mac App Store without Debug menu, simply replace “true” in the string above with “false”. The menu, anyway, is quite interesting as it allows you to play around with a bunch of hidden settings such as shadows and width in the App Store’s webview, the animations and duration of “flying icons” (when you download an app and it goes straight to the Dock). You can also enable and disable the Purchase Check, although we wouldn’t really recommend to tweak these default settings – you don’t want to break the Mac App Store app.

We think this Debug menu will be removed in a future update, as Apple doesn’t want users to modify, or even see, this stuff. Still, you can check it out for now.
