Uber is tracking your location even if you’re not using the app

Uber recently changed the way the app collects your location data. Previously Uber app was tracking your location “While Using the App”, which means iOS only reveal your location to Uber when you’re using the app.

When you run the latest update, Uber app will prompt you to accept their new policy with an explanation.

Uber is tracking your location even if you are not using the app

On iOS, an app has three location tracking options. The first is “Never”, the second is “While Using the App” and the third is “Always”. Thus in order to track your location five minutes after your trip ends, the app has to change to “Always” track your location.

So it is up to you to have good faith in Uber that they’re not tracking your location after the said five minutes. It is strange that Uber has to circumvent the basic iOS privacy protection to implement its app feature. As one of the largest app on iOS, Uber is in good position to discuss with Apple on how to properly get the additional five minutes tracking.  

You can prevent location tracking by going to Settings > Privacy > Location Services > Uber and select “Never”. Or remove the app if you’re uncomfortable about the changes.

How to reveal hidden files in macOS Finder

There are many hidden files and folders in macOS. Hidden files are used by the operating system and applications for their inner working. These files by default are not shown in Finder to keep things simple and to prevent casual users from messing with them. 

However it is occasionally useful to access hidden files especially for troubleshooting purpose. To reveal hidden files in Finder, open the Terminal app and enter the following commands:

$ defaults write com.apple.finder AppleShowAllFiles YES
$ killall Finder

The first command set the Finder default attribute AppleShowAllFiles to boolean YES in order to show files. The second command relaunch the Finder.

If you take a look at your desktop or Finder now, you can see that there are some new files that were previously hidden. A word of caution, hidden files are hidden for a reason. You can do serious damage to macOS if you don’t know what you’re doing making changes to hidden files.

To hide these system files in Finder again, repeat the same commands by changing the Finder default attribute AppleShowAllFiles to boolean NO, like so:

$ defaults write com.apple.finder AppleShowAllFiles NO
$ killall Finder
