10.12.5 lost support

[mooreaa]

Hello,

I had used your patch to get 4k@60hz support on my MST display in 10.12.4, but I recently upgraded to 10.12.5 and its drooped back to 30hz. I'm connected via DisplayPort and the fact that it was working on 10.12.4 indicates there is a software issues somewhere, just not sure what. I've tried various attempts but have not been able to get the display options to show 60hz.

Any help would greatly be appreciated
