i3 8100 | B360 Motherboard - No iGPU acceleration

[iSan4eZ]

Issue of connectors not fully enabled...
Look around for the proper "4 displays" patch for 0x59120000.

Keep in mind you usually cannot boot with all displays connected/powered. Boot with only one then test additional by hotplug/turning them on.

Also, iMac18,2 probably not a good idea. Use iMac17,1 or iMac14,1 or iMac14,2.

Note also you installed the FakePCIID kexts incorrectly...
Look closely at your kextcache output.

I'm using only one monitor. Just fixed permissions for kexts and still nothing changed after my try to get image with 0x3e928086. Why 18.2 is bad? Thought i5 7500 is pretty close to i3 8100 and selected it. If I'll change it, will iMessage stop working? And do I need to log out of iCloud?

I've managed to get 1536Mb VRAM detecting and acceleration working with 0x3E928086 and somehow working ports remapping! But flickering is way more noticeable.

Edit1:
GFX0->iGPU, disabling "-disablegfxfirmware" and "shikigva=1" makes no visual difference to acceleration and flickering

You still didn't make the SMBIOS change I suggested earlier.

iMac17.1 works perfectly fine! Thank you a lot!
Also I've tried to launch some Steam games and got error (picture attached) with app that opens on second virtual desktop.

Edit1: Tried other games and some are launching on second virtual desktop with no problems. Looks like this error somehow related to OpenGL

Also I have low volume (and quality) sound on ALC887 with VoodooHDA and wasn't able to get AppleALC to work. Debug files is the same as in previous post.

Try my config from debug I’ve sent in previous message.

It works very Good!

And you solved the audio thing?

Got it working! Delete anything u had related to audio, copy my config and install AppleHDA.kext to /S/L/E and AppleALC to Clover/kexts/Other

Edit: Got new bug - sleep reboots computer. Previously it was okay. I’ll try to fix it tomorrow. Also I’m trying to make double monitor setup working. Probably that’s what caused this issue

Edit2: Looks like sleep is working sometimes..
