Laravel dusk chrome driver timeout

Can anyone help, I am unable to get Laravel dusk to run the default sample test in my current Laravel 5.6 project on mac high sierra.

Error message

Time: 2.5 minutes, Memory: 14.00MB

There was 1 error:

1) Tests\Browser\ExampleTest::testBasicExample Facebook\WebDriver\Exception\WebDriverCurlException: Curl error thrown for http POST to /session with params: {"desiredCapabilities":{"browserName":"chrome","platform":"ANY","chromeOptions":{"binary":"/Users/keith/Desktop/dusk/vendor/laravel/dusk/bin/chromedriver-mac","args":["--disable-gpu"]}}}

I have already done the following :

added the following to app\Providers\AppServiceProvider.php

use Laravel\Dusk\DuskServiceProvider;

...

public function register()

{

    if ($this->app->environment('local', 'testing')) {

        $this->app->register(DuskServiceProvider::class);
    }

}

ran 'php artisan dusk:install' in terminal
set App_URL in .env to http://localhost:8000
specified the location of chromedriver in DuskTestCase
start 'php artisan serve' before running 'php artisan dusk'

try this while you instantiate your browser.. the most important is $driver = retry(5, function () use ($capabilities) { return RemoteWebDriver::create('http://localhost:9515', $capabilities, 60000, 60000);

Below is how i instantiate my browser

$options      = (new ChromeOptions)->addArguments(['--disable-gpu', '--headless', '--no-sandbox']);
$capabilities = DesiredCapabilities::chrome()
  ->setCapability(ChromeOptions::CAPABILITY, $options)
  ->setPlatform('Linux');
$driver       = retry(5, function () use ($capabilities) {
  return RemoteWebDriver::create('http://localhost:9515', $capabilities, 60000, 60000);
}, 50);

$browser = new Browser($this->driver, new ElementResolver($driver, ''));
