The popularity of Macs has been getting higher, and in order to master location information in Macs, sometimes we rely on device positioning services, such as Safari suggests, a feature that relies on location-based services to provide search. And we use it when the system service requests the location. Now we're going to show you how to display the location icon in the menu bar .
If you want to know when your location data is being used, simply turn on the menu bar's location service, you can monitor when your application accesses your privacy location data in OS X, and find applications for location information and "kill" them.
How to display the location icon in the menu bar in the Mac 1. Open System Preferences-security and privacy
2. Click on "Privacy"-"positioning Service", under "Enable positioning Service" down, click "Details" (Note: first click on the lower left button lock unlock)
3. Check in the pop-up box: when the system service requests your location, display the location icon in the menu bar and click Finish.
Now, for example, when a map application or some illegal application requests a location from a system service, the small arrow appears in the menu bar. Click on the arrow icon to see which application is requesting the data and doing it further.
