Gigabyte Z390 M Gaming build with working NVRAM

[pastrychef]

I noticed this a while ago when you wrote this guide, then the other day I read somewhere someone said that to get proper rendering on their Vega they had to enable IGPU with iMac Pro 1,1. I never felt like my Vega was being used at least that what the activity monitor said and the cpu use always went up. Today I set up a device property to inject the IGPU rebooted and enabled it "no WEG". Seems like DRM works at least in Appletv app, Netflix and Hulu seem to work in my browser along with HBO. But the real reason for the test was to check for hardware usage. Checked videoproc it lists the IGPU but all the activity takes place on the DGPU. Even the CPU just kind of sits around and does nothing. That was not the case before. You may have already knew this.

I do not define ig-platform-id in device properties. I just enable it in BIOS and let macOS auto detect. After booting in to macOS, it sets device-id to 3E980000 and the IGPU does not appear in System Information > Graphics/Displays.

Yes. Amazon Prime also works in Safari for me.

Yes. I see the same behavior with VideoProc.

But you use WEG right? I have to inject the info because I do not use WEG or at least in my case I have to other wise the system does not finish booting.

HDMI on macOS has always given me some problems. Even with active adaptors it does not work well.

On my 2018 Mac mini, , when I use the HDMI port, or even USB-C to HDMI from one of the thunderbolt ports it does strange stuff.

No. I've had WhateverGreen disabled since 10.15.4 because it was causing kernel panics on wake due to HDMI audio. System has been rock solid since disabling WhateverGreen.

Humm when I do not inject the IGPU info it never completes the boot, but when I inject the info under devices in OC it boots right up. It does how ever show up in a few places a headless might not like in PCI list, it shows up under activity monitor.

Hmm... Maybe there's some variation in our BIOSes...

I guess the problem was me, it seems that I should have just waited a few second longer. It seems with the injection properties it boots a few second faster.

Hi @pastrychef, hope you are covid19 free

I am building a new rig which will be same mobo as yours and have a question. Looking at the i5 9400f, I understand this had no GPU on board. Would this cause any issues as I thought macOS used some of the on chip graphics memory eg with my current system running headless. Is this something I should consider?

macOS can run fine without IGPU, just use iMacPro1,1 system definition. I currently have an i5-9400F in my Z370 build and have no issues at all.

That being said, IGPU can help video editing apps with H.264 and HEVC encode/decode. The biggest benefactor of this is probably FCPX. FCPX can still run without IGPU, but having Quick Sync can help speed up encodes/decodes considerably. If you do not use video editing apps, IGPU shouldn't matter too much for you.

Thanks mate. Components arrive Saturday. I can't wait. Built a PC for a friend last week using this board and WD SN500 NVME SSD, that is what is costing me money. Not used NVME before, man it flies!

Quick question, do you know what the bits in red circle below are?

Hope you don't mind if I come back to you for help when components arrive, I'll use your guide but sure I'll get stuck at least once
