Selling for far less than everyone else.

You get:

Flashed Titan Ridge Thunderbolt 3 card.

Two DisplayPort to mini DisplayPort short cables.

I’m not going to include OpenCore files or a guide Google is fine.

SMC Rest your MacPro 3x or so after you get the proper OpenCore files. I feel like they are a given with the OpenCore Legacy patcher.

Google your way through it and save money.

I think I have 3 of these. This one I’m selling works well. I’ve successfully used it on a dell 27” USBc monitors.

If you want your classic Apple thunderbolt to work with this, the easiest way is with a second monitor getting a video signal over the other Thunderbolt port.

And please think rx560 or better.
