If you’ve downloaded the Safari build on Windows, and you want access to the very helpful debug Develop menu (the javascript console, DOM viewer, etc), Do the following:

1. Open %APPDATA%\Apple Computer\Safari\Preferences.plist (Or open C:\Program Files\Safari\Safari.resources\Defaults.plist)
2. Add the key / value:

...
<key>IncludeDebugMenu</key>
<true/>
...

for reference on Mac it’s:

$ defaults write com.apple.Safari IncludeDebugMenu 1

From the terminal.

In both cases you’ll have to restart Safari if you already have it open.

Also, in case you go to try it, it seems Safari doesn’t like to be run over a Remote Desktop session coregraphics.dll doesn’t like it.
