I am developer and I'm trying to simulate a different location other than my own on Safari on OS X (El Capitan). How do I do that?
EDIT: This is not a duplicate of how might one spoof geographic location on a desktop Mac. That question is about spoofing the location system-wide. I am not trying to (and actually don't want to) spoof my location system-wide, I just want to change it for Safari only.
