Make sure you are pointing to the right folder using “Chrome://version”.
I am using the windows but it should be similar in you mac case too.

How to create a custom profile:
You can create your own custom profile by just running Chrome (on the command-line or through ChromeDriver) with the user-data-dir switch set to some new directory. If the path doesn’t exist, Chrome will create a new profile in the specified location. You can then modify the profile settings as desired, and ChromeDriver can use the profile in the future. Open chrome://version in the browser to see what profile Chrome is using.
