Download Sublime text and open in S/L/E AppleIntelAzulFrame.kext(i not sure this real name ) and search
0600 260a
edit under line and save. Use Kext Utility install the S/L/E and reboot system(Dont forget the back up kext)

The reboot with HDMI hot plug issue can be fixed by installing WhatEverGreen and configuring the IGPU device properties to change the pipe to 12. This is much better solution as the framebuffer is dynamically patched at MacOS boot up rather than statically patching the Apple driver kexts which would need to be re-done each time you update the system.

The process is explained in @CaseySJ guide :-

I pass you IoReg I have to make one cable at a time

I did this on my Haswell based Media Mac (see sig for specs) on both HDMI ports and it works great, you can also configure the port flags to enable HDMI audio. This is what my IGPU device properties look like :-

            </dict>

The above code should also work for you, the only thing to check is which connector(s) number9s) your system is using (you can use Hackingtool to check). In the above code the two HDMI connectors on the motherboard are con-1 & con-2.

The code needs to be added to your Config.plist in the Devices -> Properties section.
