This time it gives me kernel panic and turns the screen off at the same moment.
BTW if I put any supported nVidia VGA will I be able to install without problems ?
EDIT:
I managed to somehow install El Capitan on the same configuration. Now the only problem is that it shows HD 4600 with 5mb or 7mb memory in system>about this mac. Also the screen is flickering and I thing QE/CI is disabled. In system profiler it says kext not loaded but it shows the vga with ID and everything normal. I tried with FakePCIID.kext and FakePCIID_HD4600_HD4400.kext but does not work.
