Menu bar shows that macOS Sierra very frequently uses location services to check the time zone even though Setting Time Zone is disabled Ever since upgrading to macOS Sierra, I have been able to keep track of when programs use my location because the menu bar displays an icon whenever an app requests this information. I have noticed that about once per hour, the location services icon appears for a few seconds, and when I click on it it says "Apps requesting location: Setting Time Zone"

I've tried disabling automatic time zone detection in System Preferences (Under the Privacy > Location Services options), and this does not prevent this from happening. Here is what this setting looks like on my computer, note that the "Time Zone" box is already unchecked:



I looked at the list of other programs that have recently requested my location, and nothing unusual appears:



What is causing this, and is there any way to disable it? If this cannot be turned off, then is there a way to prevent it from appearing in the menu bar?
I had the same issue on macOS 10.12.6. Give this a try:


Under System Preferences > Date &amp; Time > Time Zone: Uncheck "Set
time zone automatically using current location"
Disable location services completely
Delete the file "/Library/Caches/com.apple.AutoTimeZone.plist"
Reenable location services again
Restart your computer


Does it solve your issue? Source
