Netflix Not Working in Safari on macOS Sierra?

Hello,

I have not been able to get Netflix video to work in Safari on my iMac but Netflix works fine on Safari on my MacBook. I am running an iMac (macOS Sierra 10.12.3) and Safari (10.0.3) on both computers.

What I have already tried:

• Yes, I have installed Silverlight.
• Yes, I have already uninstalled and reinstalled Silverlight.
• Yes, I have cleared the cache numerous times.
• Yes, I have reinstalled macOS Sierra from scratch.
• Yes, I have disabled all Safari extensions.
• Yes, I have tried other browsers but I want to use Safari.
• Yes, I have copied Safari App from other computers.
• Yes, I have disabled all security software.
• Yes, I have tried running Safari with no other Apps running.
• Yes, I have updated all apps and macOS.

*None of this worked*

Does anyone have any other ideas?

Thank you,
Shane
