您需要使用AuthorizationExecuteWithPrivileges ，例如， 请访问http://www.michaelvobrien.com/blog/2009/07/authorizationexecutewithprivileges-a-simple-example/

// Create authorization reference
AuthorizationRef authorizationRef;
OSStatus status;
status = AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment,
                             kAuthorizationFlagDefaults, &authorizationRef);

// Run the tool using the authorization reference
char *tool = "/sbin/dmesg";
char *args[] = {NULL};
FILE *pipe = NULL;
status = AuthorizationExecuteWithPrivileges(authorizationRef, tool,
                                            kAuthorizationFlagDefaults, args, &pipe);
