Allow apps to detect the location of your Mac
Location Services allows apps and websites to gather and use information based on the current location of your Mac. Your approximate location is determined using information from local Wi-Fi networks, and is collected by Location Services in a manner that doesn’t personally identify you.
Turn Location Services off
On your Mac, choose Apple menu
in the sidebar, then click Location Services on the right. (You may need to scroll down.)Turn off Location Services.
If you turn off Location Services on your Mac, your precise location is not sent to Apple. To deliver relevant search suggestions, Apple may use the IP address of your internet connection to approximate your location by matching it to a geographic region.
Even if you turn off Location Services, third-party applications and websites may still use other ways to determine your location. For safety purposes, however, your Mac’s location information may be used for emergency calls to aid response efforts regardless of whether Location Services is turned on.
Specify which apps and system services can use Location Services
On your Mac, choose Apple menu
Turn Location Services on or off for each app in the list on the right.
If you turn off Location Services for an app, you’re asked to turn it on again the next time that app tries to use your location data.
Scroll to the bottom of the list of apps to reveal System Services, then click the Details button to see specific system services that use your location.
To allow the location of your Mac to be used by Siri Suggestions and Safari Suggestions, turn on Location-Based Suggestions.
To allow your Mac to identify places significant to you and provide useful related information in Maps, Calendar, Reminders and more, turn on Significant Locations. Significant locations are encrypted and can’t be read by Apple. Click Details to view a list of locations that have been identified. You can select and remove locations from the list or click
> Clear History to remove all the locations.
In macOS 13.3 or later, a blue dot

If you allow third-party apps or websites to use your current location, any information they collect is governed by their terms and privacy policies. It’s recommended that you learn about the privacy practices of those parties.
When you use Safari Suggestions or Siri Suggestions, the location of your Mac at the time you submit a search query to Safari or Spotlight is sent to Apple to make suggestions more relevant and to improve other Apple products and services.
