If MapQuest.com in your Safari browser isn't locating you properly, or if you've denied MapQuest permission to use your location in the past but want to grant that permission now, you can easily reset all website location requests in Safari by following these easy steps:
- Click the Apple menu icon in the top left of your screen
- Click System Preferences then Security & Privacy
- Make sure you are on the Privacy tab then choose Location Services
- Check Enable Location Services (if the padlock is on click it to unlock)
This will ensure that you are asked if it's okay for MapQuest to use your current location the next time you visit MapQuest.com.
