Iris Pro 580 not working in Sierra - glitching and 6MB VRAM

[superslurt]

Hi everyone!

Last week, I tried to install Sierra since I needed the latest version of iWork. Shouldn't have done it.

It's an Intel NUC6i7KYK Skull Canyon, see my signature for details

El Capitan was installed per Rehabmans guide, and it has been working very good the last months. I then optimistically upgraded to Sierra, also following Rehabmans general upgrade procedure.

Everything works, except for the screen. It flickers/artefacts really bad, and the GPU is reported as "Intel Iris Pro Graphics 580 6 MB". System profiler reports "Kernel Extension Info: No Kext Loaded".



Video memory in bios is set to 64mb/256mb. I tried different values, but it would only lead to a sudden reboot right before the login screen. I have also tried changing the SMBIOS to iMac 17,1.

My current Clover version is 3911.

Does anyone here have a clue to what might be wrong with this install? Any tips or tricks to try?

I appreciate all the help I can get

PS: I have attached a ZIP with my EFI folder and some console outputs.

There's no Macs using Iris Pro 580.
But you can try, setting InjectIntel=True and maybe have a ig-platform-id also.

Hi robinhuang.

That's true, but the thing I find strange is that the 580 worked perfectly in El Capitan.

InjectIntel is already set to true, and I have tried these different ig-platform-ids.

I'm having this problem too. Or at least it's similar. Every so often the screen (totally unpredictably) will go completely blank for a second. Still no solution to this. It appears to only be a problem over DisplayPort and not HDMI.

I am using High Sierra 10.13.1 on my NUC6I7KYK which has Intel Iris Pro Graphics 580 and I am typing this post on it now.
It is working great.

It take back my last post, while I am using it, iTunes Movie DRM playback is black screen, the video is there & downloaded it does not play, and it does not stream. I really need to figure this one out.

Did you follow the NUC guide?

For DRM playback you may need to use Shiki.kext (I don't use DRM content, so no experience with it).
