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

[CaseySJ]

@CaseySJ have you seen the forum post where the creator of OsxAptioFix2Drv-free2000 tells we shouldn't use that? There's also people that got it working using other drivers on Z390 models like Designare, Aorus Pro, etc

Yes we had a long discussion about this circa July 23. If your system is bootable with AptioMemoryFix (which will soon be replaced with FwRuntimeServices), then it’s advisable to use it. My system, however, does not boot with anything other than OsxAptioFix2Drv-free2000 when (a) IGPU is enabled and (b) WiFi/BT card is installed.

Hello guys, I had a problem where I could not boot my Z390 Ultra board with the iGPU enabled, but disabled it would boot fine. The solution for me was change out AptioMemoryFix for OsxAptioFix2Drv-free2000.efi The symptoms would be I set IGPU to angled and then I would get a stop sign...

I was wondering: do we need the iGPU or can the Radeon VII handle everything like Preview and decode of H.264/H.265?

Not sure if the Radeon VII drivers are mature enough to handle it all?

Asking because I have ordered a Radeon VII for my build based on this thread.

On the iMac Pro and new Mac Pro (and even the old Mac Pro) the Intel Xeon CPU lacks a build-in GPU. And yet everything still works! So the duties normally relegated to the IGPU are instead dispatched to the discrete GPU. Switching sysdef to iMac Pro is one way to do this on a Hackintosh, but other sysdefs can also do this to varying degrees.

P.S. Please take a moment to enter your CPU, GPU, and motherboard information here.

Actually, this is a glitch when passing through to second-stage on boot. Normally we are seeing white flicker on AMD when passing through to second-stage on boot. With HD 630 we are seeing a glitch. I think this is normal, isn't it?

Also, I realize something, when open anything with Quicklook, it looks like this;

Oh yes that’s not good...

Feel free to post your config.plist with serial numbers redacted.

Would you like to try this @CaseySJ ? I have had stable boots with this for the longest time (IGPU only).

Hello,

Wanted to confirm this finally for all of us disappointed that we cannot run an LG 5K at 5K. If you use the Mac OS "Scaled" resolution you are getting 4K anyways. You will only get more pixels if you use the "Default for display" resolution on your LG 5K, which for me, is too small anyways.

You can see the pixel counting here done in Sketch App. As you can see, even when running 4K at 4K on the LG 4K (I have 2 LG 4Ks and 1 LG 5K) the pixels match, although smaller, as when running scaled.

Just FYI

Yes, there's no way to run it at 5K with this mobo. You still need 2xDP-in ports sadly.

Yes, I'm aware, but what I am pointing out is that if you run at a "Scaled" resolution, running at 5K (like with the Titan Ridge card in a different motherboard, or even using a real Mac) will give you no benefit whatsoever.

Actually, I did weird thing and it worked. As far as remember after v10.14.5 update, IGPU automatically defining by the system. I removed the device id and ig-platform-id from devices/properties panel and just leave the HDMI port settings. Now I can get full acceleration with no white pieces on 19,1 SMBIOS. System defining automatically device and ig-platform-id by itself.

But boot flicker persists.

No ig-platform-id and devices id.

I haven't gotten it to work either but might try to revisit. What do you have in your kexts/other and L/E folder?

Thanks,

One last thing that confuses me a bit: You add SSDT-Z390-DESIGNARE-RX580-V2.aml for your system. You note that "Display devices "AMD RX 580" and "AMD RX 580 Audio" in System Information."

Does this mean that this is purely a cosmetic fix? (as us with Vega cards do not need to add any SSDT? with the latest Mojave)

Sorry if it is a stupid question!
