Actual script (beginning)

require('chromedriver');
var webdriver = require('selenium-webdriver'),
By = webdriver.By,
until = webdriver.until;
var driver = new webdriver.Builder().forBrowser('chrome').build();
var timeout = 15000;

I had similar error. But versions were matching: I was using Chrome 65 with driver version 2.38.

I spent long time, trying to understand the issue. At the end, found that it was caused by empty /etc/hosts file. Apparently Chrome communicates via localhost, and if such entry missing in /etc/hosts - it will crash.

So, make sure, it has entry like this:

127.0.0.1 localhost

You are using the chromediver 2.32 and in the release notes there is written that the support is for Chrome v59-61

As browser you have:

Chrome Version 62.0.3202.62 (Official Build) (64-bit) 

So, from ChromeDriver, you should use the 2.33

Here's an brew addendum to @davide-patti solution. :)

When I was getting the error unable to connect to renderer, I learned from @davide-patti that I was using an older version of chromedriver, v2.32. But I was unable to upgrade my chromedriver with homebrew, as I received continually: No available formula with the name "chromedriver".

This article helped me a lot to upgrade to v2.33+.
