I’ve been using CAC-1170 to connect my MacBook Pro 2015 with Sony X800D for nine months and this adapter is very finicky. It took me several hours to get it playing nice with El Capitan using SwitchResX. It stopped working when I upgraded to Sierra and I had to go through the same process again. Couple of months ago, I was away for a month, and when I came back and turned it on, the screen shows just a green bar on the top, and only shows the content when I reduce refresh rate to 30Hz. [email protected] doesn’t work anymore.
