How to find the Team ID of an application on Mac

Team ID is a unique identification code given by Apple to a developer inside the Apple ecosystem. Team ID can be used to identify all the applications developed by a particular developer. Team ID is provided by Apple and cannot be changed by the developer. You can have multiple applications under the same Team ID.

We can utilize Bundle ID to uniquely identify an application that comes under the same Team ID, which will be unique for a particular application.

Find the Team ID of an application in a macOS device

To find the Team ID of an application that is already installed on a macOS device,

  1. Find the location/path of the application for which the Team ID is to be found. To find the location/path of an application, right click on the app and select “Get Info”. The location/path of the application will be displayed beside “Where”, which can be used in the command to find the Team ID of the app.
  2. Enter the following command in the terminal:

    codesign -dv --verbose=4 /Path/to/app\ app_name.app/ 2>&1 | grep TeamIdentifier

    A sample terminal command to find the Team ID of the Google Chrome app is given below:

    codesign -dv --verbose=4 /Applications/Google\ Chrome.app/ 2>&1 | grep TeamIdentifier

Upon entering the command mentioned above, the Team ID of the application will be obtained as the result of the terminal command. It will be displayed in the format:

“TeamIdentifier=ABCD1234”

You can use the Team ID of an application when you configure System Extensions or Kernel Extensions for your macOS devices.
