title: Selenium gives "selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary" on Mac
body: <p>Trying to get <code>selenium</code> to work with Python 3 for web scraping purposes:</p>
  
  <pre><code>from selenium import webdriver
  chrome_path = r"/Library/Frameworks/Python.framework/Versions/3.6/bin/chromedriver"
  driver = webdriver.Chrome(chrome_path)
  </code></pre>
  
  <p>I get the following error message: </p>
  
  <blockquote>
    <p>selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary</p>
  </blockquote>
  
  <p>A similar question was addressed <a href="https://stackoverflow.com/questions/43287203/selenium-gives-unknown-error-cannot-find-chrome-binary-when-running-chrome-dr">here</a>, but what is baffling to me is that Chrome is already installed on my system. The other asker apparently didn't have it on their computer. I'm running latest version of Mac OS.</p>
