I have a 2014 15″ Macbook Pro Nvidia 750M 2 GB and a Vizio M50-C1.
Step 1: Install latest firmware update for CAC-1170 adapter. Email [email protected] to get the latest firmware.
Since the firmware installer is an .exe (Windows only), you need to use a Windows laptop with a AMD, Nvidia, or Intel graphics card to install the firmware on the adapter. I borrowed a friends laptop with a Nvidia GTX970M card to install this firmware. Follow the instructions in the email from [email protected].
