How to Fix Netflix Error N8156-4001 and Silverlight on Mac OS X

Jan 21

This will be a short post in effort to help others. I was streaming Netflix tonight, or attempting to, and kept getting an error code N8156-4001 with a message to call support if it doesn’t go away. This was not a happy good feeling, nor was I going to call customer support – I’m far too lazy to wait in line.

So, I did a little research and found tons of others experiencing the same problem, and that it’s related to the Microsoft Silverlight Plugin. I found that many people said re-installing or downgrading Silverlight was doing the trick. Though I couldn’t find just how to do that as they rarely posted instructions for Mac OS X, hence this post.

The steps I finally came up with are dirt simple and hopefully work for others too. I’m not sure what remnants I left on my computer by installing over top like this, but frankly, I could care less – it works! 🙂

The steps:

  1. Go to the Apple Silverlight download page, and download Silverlight 3.
  2. Unpackage the download
  3. Click through the friendly wizard
  4. Restart firefox

Wallah! I logged back into Netflix, and the error was gone. I’m now about to fall asleep to a sci-fi.

If others have tips, please post in the comments.
