Note that you should never run a GUI application with elevated 
provilege, particulary an application that uses AppKit, this is EVIL.

See man authopen(1).  This is built-in an helper tool design to read 
and write file using auth services. It handle all the authorization 
part for you.

And before using ExecuteWithPrivileges, you must read this:
