My MacBook Pro with Retina display shows wrong current location
I purchased my MacBook Pro when I was a student at a particular university in Hawaii. After I graduated, I moved back to my home country in the Philippines. When I use Google Maps or Bing Maps to show me my current location which is now in the Philippines, it still shows that I'm still at that university in Hawaii. I tried using the Find My iPhone App, it shows my iPhone's and MacBook Pro's location in Hawaii but not at my current location in the Philippines. I tried resetting the PRAM, changing region settings, and even my timezone manually, but still having that wrong location info whiich I need in case I lose my iDevices and try to locate them and they'll all point to Hawaii!
Please help! Thank you!
MacBook Pro with Retina display, OS X Mountain Lion (10.8.3)
