Enabling the Developer / Debug Menu to Safari

With OS X Mountain Lion, Apple has removed certain useful facilities, like the command-key shortcut for clearing the browser cache.

Clearing the browser cache and many other useful features are added to a Developer menu as follows.

Open Terminal (/Applications/Utilities), and enter this command:

defaults write com.apple.Safari IncludeDebugMenu 1

Quit Safari and restart it, and the new Develop menu will appear.
