Location Services on MacBook Pro

I am trying to activate "Location Services" on my MacBook Pro so I can use the "Find iPhone" section to locate the MacBook if it was misplaced. How do you set-up "Location Services" on a MacBook? I go to the System Prefs and choose "Security & Privacy", go to the "Privacy" tab but the "Enable Location Services" is grayed out. Would sure appreciate any help. Thanks.
