Hello. I have followed this tutorial and created my Dual Boot El Capitan / Win 10 build successfully.
Wifi -> Works
iMessage -> Works
All USB ports -> Work
Shutdown shuts down the computer without the restart bug.
I cant get the dual monitor working with integrated graphics. I am connecting the first monitor with DVI and the other monitor with HDMI through my motherboard (H170N - WIFI, my CPU i5 Skylake HD530).
Note:
1) Dual monitor works in Boot mode but when it boots to OS X, the first monitor goes black and the other has fuzzy graphics and I am able to see the top bar only.
2) Dual monitor works perfectly in Windows 10 with both monitors in 1080p 60Hz.
I have tried the hot plugging method, no results. Any suggestions ? Thanks for this build I love it!
