How to debug Laravel Dusk chrome-driver not starting automatically on macOS Catalina?

Have you tried starting dusk using verbose logging if it gives you some pointers on why chrome is not launched:

php artisan dusk --verbose

@nakov Thanks for following up :) The only additional output I get from that is which config file it is using:

pa dusk --verbose
PHPUnit 8.5.2 by Sebastian Bergmann and contributors.

@mikebronner I did a quick search on your issue and there are couple of closed issues on the github page related to an older version of dusk or the chrome browser. Make sure you have those updated and also that you have the chromium driver installed for your OS: https://laravel.com/docs/5.8/dusk#managing-chromedriver-installations

@nakov Thanks, yes, I have done all that. Both the Chrome browser and the driver are updated to latest.
