step 6

and have a look Devices Installed, you should remove all devices witch is NOT LOAD,
I am not able to understand the above steps 5 & 6, can you be more specific with example and screenshot?
thanks

So Wen you export config.plist and reboot system lost audio.
and that why you should delete this 3 devices.
2 of them are AMD radeon 1 video + 2 audio
and 3 one are mainboard audio.

right here look photo > Clover >Device > Properties
and find this 3 one. delete it and reboot


step 6 look 2 screen shot. delete all devices witch are NO. they are not loaded and yours system not need it.

thanks, now in videoproc both h264/265 are enabled under hardware acceleration in Hackintool VDA Decoder is fully supported but in Safari Netflix and prime videos are not working.

Also one question about the patch which is generated as per your guide. Is it necessary to generate the additional patches for PCI devices or patch for only frame buffer can also work?

The machine works perfect in other regards like sleep/wake using dGPU for hardware acceleration etc. My machine with my previous setting also worked well except videoproc only supported H265 and Hankintools would report VDA Decoder not supported. Safari playing Netflix or amazon prime not playing has no effect for me as I never see those on my computer and anyway in chrome it is playing so no loss. But your setting makes my machine now more like a true imac, a BIG THANKS

oh! I noticed just now that I have not put -disabegfxfirmware in the clover boot option, will this make any difference? what this flag is used for?

right now I make few new test. 8700K
till now I use AAPL,ig-platform-id : 0300913E , because on other 2 option for 8700K not work ( 0300923E, 07009B3E )
but now I change it and everything work perfect , I prefer 07009B3E because it give it work on Imac19,2/macmini8.1 (i7 - 8700/8700B) and I'm using Imac19,2
So I'm tested only 10 min but wen I sow in Graphics/Displays it show Radeon RX 580 (Slot 0, GPU 2):
that mean system recognise 2 GPU and should work.
but again DRM - TV not work. I will make more test.

1 Reboot after Wake
2 Little more time to boot

Why Intel KBL Unknown GPU?

But as seen from the pics both GPUs are working perfectly. Netflix and prime not working
Tested with the flag also same things.
Why to use shikigva=16 flag?
