   Configure this options screen as follows:

     Leave the other settings at their default values. Make sure all the checkboxes are unticked. Click Next when done.

9. If you see a dialog box saying No author information was supplied by the version control system, click Fix.

   Important information

   The reason why you see this dialog box is because the Source Control checkbox is ticked. Apple recommends that Source Control be turned on. To learn more about version control and Git, refer to the following link: https://git-scm.com/video/what-is-version-control

10. You will see the Source Control preference screen as follows:
