On all the other Macs in the house when you go to the Security system preferences and then the General tab their is a section that allows you to disable or enable location services (all running Mac OS X 10.6.7) except on my 2006 Mac Pro which does not have any location services options at all (screenshot attached). Does anyone know why this? Or what you need to do to enable it? I need it to access location services in the iPhone simulator. Any help is very much appreciated.
