Screen Shot 2013 06 04 at 16.51.41 150x150 OS X & Google Chrome NTLM AuthenticationGoogle Chrome for OS X generally doesn’t play well with proxy servers, especially those that require NTLM authentication. Those who have tried to use it in the past will be greeted with a constant barrage of proxy authentication prompts, each successful entry of credentials loads a tiny little bit more of the site..

However, there is a way to resolve this. Using a simple command in OS X terminal you can enable NTLM authentication in Chrome, and only have to enter your credentials once.

  1. Open Finder
  2. Open the Utilities folder
  3. Open a terminal window
  4. Copy and paste the following line in:
    Sudo /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --auth-schemes="ntlm"
  5. Enter your password and press enter
  6. Now quit and relaunch all Chrome windows.

That’s it. You should never be prompted again, at least not until you change your password.

    Thanks for the tip. It works perfectly but it is not permanent. I have to open Chrome with this command every time. Is there a way to make chrome open with the desired scheme?
