[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

[hylkepylke]

Messages, FaceTime, and iCloud are working with Clover + EmuVariableUefi. Because EmuVariableUefi is incompatible with OpenCore, I agree that NVRAM is an issue there.

I also want nvram to emulate a real Mac as much as possible: my old Hack and my laptop also have nvram working, I'm a bit scared of what might happen w/o it.

In addition to Inject Intel, please add the fake ID in Devices (IntelGFX = 0x12345678) and set ig-platform-id to 0x3E9B0007 from the pop-up menu in the Graphics section of Clover Configurator and try again.

If it still fails, add the boot argument -wegoff and try again.

Right on, will try tonight. Thanks!

Because you have two 32GB DIMMs, the problem might be related to memory. Suggestions:

• Remove one DIMM and run the macOS installer.
• If it still fails, do you have 8GB or 16GB DDR4 DIMMs?
  • If so, try those instead of 32GB modules.
• Let us know if it still fails.

Hey, thanks for the help.
Heres what i tried:

• started from scratch with a new 16gb flash drive instead of the 32 i was using (no good)
• used the catalina installer version of clover, along with replacing the files you suggested (no good)
• tried booting with one stick of ram (slot a1, no good)

Will try tonight:

• buying a brand new USB stick
• going to try to use older ram I have laying around in a smaller package.

No need to buy another USB flash drive -- the problem is most likely elsewhere.

Is your motherboard on BIOS F6 or newer?

BIOS version F7

One thing I noticed, and I've tried it both ways, but just thought id mention it. When you select the 19,1 model in the configuration tool, there's a NEW model that pops up that is different than the one that is shown in the first post. Not sure that would make a difference. Also, someone had mentioned to me at the office here that I may have to manually set the RAM speed in the BIOS. Could that be an issue if theres a mismatch or would the bios have picked that up automatically?

Super excited about the success!
and thanks again for the port multiplier, getting one right now!
And yes, i can only install Catalina with the checked InjectIntel and fakeid as 0x12345678, just like @heyelly mentioned before.

Experimental Mini-Guide for swapping from Clover to OpenCore on Catalina 10.15.1​

This guide is experimental, I haven't tested everything yet, I take no responsibility if this breaks your setup, use at your own risk. This is by no means ready for production, as a sysadmin would say.
...

Thank you for this guide. I expect to compare your setup against the one I created this past weekend, with an effort to make it work with an AMD 5700-series GPU. SMBIOS will be iMacPro1,1 because FwRuntimeServices continues be problematic with iGPU enabled. I'll also try iMac19,1 with iGPU disabled (yes, a Frankenstein configuration, but then all Hacks are Franks...).

Good feedback. When we set IntelGFX (under FakeID) to 0x12345678 and we enable InjectIntel, it disables the iGPU driver called AppleIntelFramebuffer. This means no iGPU acceleration and you may see various image artifacts on screen. But fear not because once Catalina is installed, we can go back and undo this (i.e. uncheck InjectIntel and remove 0x12345678). That should restore acceleration to the iGPU.

Will have to put this into the Catalina Mini-Guide shortly...

UPDATE: done.

OpenCore has a different way of handling emulated NVRAM, but I have found their solution does not retain my boot order.

Otherwise, I have OpenCore working on Catalina without iGPU (their quirks unlike OcQuirks don't get us past the runtime allocation error with iGPU on).
