Sorry for being a total beginner in cocoa and for asking the following stupid question, but it's too confusing for me to google it myself or maybe i'm just missing something.

I need to run a shellscript with elevated privileges in cocoa. As i understand, "AuthorizationExecuteWithPrivileges" is the correct way to do it. So i've created an application and tried to use some code from one example i found online. The problem is ... if i understand it correctly ... there should be a Security framework in /System/Library/Frameworks that i have to import to the project, but ... it's not there. What am i missing here?

Thank you.
