Protractor ERROR - Unable to start a WebDriver session

I'm trying to run the plain vanilla Protractor example at http://angular.github.io/protractor/#/. I've done all the steps, but I get the errors below.

I have tried the solutions HERE and HERE with binary: "/Applications/Google\ Chrome.app" and binary: "/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome", and neither works

I'm not really sure what else I can configure; it just doesn't seem to work. Any idea as to what I can do to get it working?

EDIT I can see the status at http://localhost:4444/wd/hub, so not sure if the problem is with protractor config or with webdriver-manager.

Error in webdriver-manager:

I was able to narrow it down to a problem with finding/initializing Chrome by changing to Firefox instead:

exports.config = {
  seleniumAddress: 'http://localhost:4444/wd/hub',
  specs: ['spec.js'],
  capabilities: {
        'browserName': 'firefox'
  },
}

This configuration works fine and runs tests in FF.

With that I dug around until this thread: https://github.com/angular/protractor/issues/1424 and saw that chromedriver has compatibility issues now and then.

So I tried different versions found at http://chromedriver.storage.googleapis.com/index.html and ended up replacing the latest version (2.13) which was at /usr/local/lib/node_modules/protractor/selenium/chromedriver with an earlier version (2.9).

This solved it for me.

UPDATE

Looks like installing the newer Chromedriver version 2.15 could also solve this problem

I went to the similar issue 

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

and downgrade of chromedriver from 2.14 to 2.9 solved this issue. Windows 2008 R2 Ent , Chrome Version 41.0.2272.101 m. The strange thing is that on 'identical' system it worked with chromedrive 2.14. One more finding. Setting -Dwebdriver.chrome.logfile=chromedriver.log produces empty log for 2.14 while 2.9 writes is log OK
