I have tried this on two mac machines and both produced the same error mentioned above

As the message suggests, make sure your port 4444 is not being already used...

[joeSaad]

I cleared that port several times and made sure nothing is using it. Still the error message appeared.

Unfortunately, we can't reproduce this. What you can do is creating a nightwatch.config.js in your project (which will be merged into the default config) to specify a different port.

Similar error here, and finally fixed by upgrading chromedriver, inspired by SeleniumHQ/selenium#3001 (comment)

# fix

+    "chromedriver": "^2.42.0",
