title: Can't remove old version of ChromeDriver on MacOS
body: <p>I have a very annoying problem with ChromeDriver. I need to use version 2.36, but I currently have 2.35.528157 (when doing <code>chromedriver -v</code>).</p>
  
  <p>I have already done:</p>
  
  <pre><code>brew upgrade chromedriver
  </code></pre>
  
  <p>Which ran successfully, however according to my terminal, I still have 2.35.528157</p>
  
  <p>I then did a</p>
  
  <pre><code>brew cleanup chromedriver
  </code></pre>
  
  <p>which got rid of versions 2.34 and 2.35 according to its logs, however when I do <code>chromedriver -v</code> I still get 2.35.528157.</p>
  
  <p>If I do: <code>brew list chromedriver</code>, all I get is the following:</p>
  
  <pre><code>/usr/local/Cellar/chromedriver/2.36/bin/chromedriver
  /usr/local/Cellar/chromedriver/2.36/homebrew.mxcl.chromedriver.plist
  </code></pre>
  
  <p>Am I missing something?</p>
