title: Unknown option: -Dwebdriver.chrome.driver when running selenium server standalone on Mac
body: <p>I was trying to manually run <code>selenium server standalone</code> on MAC and then run my tests with intern-runner in Chrome browser. As I've been advised on intern User Guide: </p>
  
  <blockquote>
    <p>"To use <code>ChromeDriver</code> and <code>IEDriver</code> with a Selenium server, the driver executable must either be placed somewhere in the environment PATH, or their locations must be given explicitly to the Selenium server using the <code>-Dwebdriver.chrome.driver (ChromeDriver)</code> and <code>-Dwebdriver.ie.driver (IEDriver)</code> flags upon starting the Selenium server."</p>
  </blockquote>
  
  <p>I started the Selenium server and put path to chrome driver on my machine, but got error:</p>

  <p>any idea on why <code>seleinum</code> unable to recognize the options? </p>
  
  <p>Is there any  other solution on how to run <code>chrome webdriver/IE webDriver</code> from command line with selenium standalone server? </p>
  
  <p>Where the driver executable could be placed in the environment PATH on MAC?</p>
  
  <p>I was able to run chrome driver separately with out any issues using: </p>
  
  <pre><code>./node_modules/.bin/chromedriver --port=4444 --url-base=wd/hub  
  </code></pre>
