I want to elevate my app's privilege to super-user. Installer app supports this by displaying this dialog. How can I show this dialog to elevate privilege?

PS. I'm making a kind of packet sniffer application on Mac OS X. I'm using pcap lib. (which is part of tcpdump)

Answer 1

AuthorizationExecuteWithPrivileges with kAuthorizationRightExecute

See BetterAuthorizationSample

As a general rule, you should not run GUI applications as root. You should make a command line tool that you can run as root, and control it from your user space GUI application.
