Are you sure it says "Mac OS X" not something developer tools related?

It is normal if Developer Tools wants to enable Developer Mode on your Mac, thus, you don't need to enter an administrator password every time you start debugging your app in the simulator for the every first time after each Xcode launch.

But if you don't have enabled Developer Mode, when it was offered by Xcode, then be prepared, that Xcode will ask for an administrator password for the every first time you launch debugging in the simulator after each Xcode launch.
