Hello guys, I’ve just purchased a cac-1170 to run 4k@60Hz on my Macbook pro Retina Mid-2012 in my Samsung 40″ UHD TV UN40KU6000 60Hz. I’ve tried all the procedures with El Captain SIP + Switchresx Custom setting however the status is “NOT ACTIVATED – Invalid? “. PS. I noticed a slight improvement in speed compared to a HDMI port but still @30Hz Max on a Mini Display port. Is it possible to make that working in this macbook pro? Any Help? Cheers
