Thanks for your fast anwser! That is such an unexpected behavior. I don't plan to use Windows on this machine so it should not be an issue, I hope. Thanks again!

Hi @Jeipiika thanks for your work! Did you get any news regarding the internal drive detection issue? I'm planning a similar build (with same motherboard), but I need to use several internal nvme+sata disks.

Getting Thunderbolt to work is not only about the OC folder but also flashing a new firmware for the Thunderbolt controller and the 4.40C BIOS version. I tried to do the whole process, the TB port seem to be recognized by the OS but got no luck with anything plugged into it yet.

Well, not really. More a workaround. The issue is still here.

That was my first thought but I still dont get the logic. For example when you have <key>@0,name</key> <string>ATY,Orinoco</string> Does it mean that only the first port (identified as 0) is mapped regarding the Orinoco table, but other ports are still default? Or do we need to set the...

Can confirm this behavior, using same motherboard with BIOS v4.40 and a RX590, running Mojave as iMac19,1. Was such a headache to figure this out! However I still cannot boot as soon as I change the framebuffer name, under the @0,name key. By the way, anyone knows what the "@0" of this refers...

Thanks for the help! I removed all device properties attempts related to the dGPU then installed your SSDT. Same result as previously: dark screen at the middle of the boot. If I wait a few minuts the computer restarts by itself, and the macOS partition no longer appears in OC. Need to do a cold...

Whoops I've read too fast, my bad! I assumed it was for the Phantom Gaming version as it is what this thread is about.

Thanks for pointing that up! What kind of benefit should I except compared to the layout 7 we are using right now?

I guess you can try to use HWMonitorSMC2.

Yes, WEG is here, up to date and successfully loaded during boot. I am using iMac19,1 since the beginning already...

Hey, I'm looking for an OpenCore alternative to the Clover method constiting in checking "injectATI", setting a framebuffer name and a port count, all this for forcing macOS to use another framebuffer instead of the default ATI,RadeonFramebuffer. In my case I want to try the Orinoco framebuffer...

I know it is without space, just wanted to point it out to @fryysyd . Already tried with and without agdpmod=pikera and no difference. so far. I did try other video ports (both HDMI and DP, I have no DVI), same result. This GPU has two HDMI, two DP and one DVI so Orinoco should actually fit...

It should have something to do with your graphic card. You can try to plug your monitor to another input, maybe also update WEG. Those are really my 2 cents.

Thanks for explanations and the fix. Very informative and helpful! I find it crazy that this topic isn't more present in hackintosh dual boot forums/guides.

I'm still a true n00b when it comes to troubleshooting. I switched to the OpenCore debug version, set "Misc/Debug/Target" to 67 to produce log files, and I added -v. However from my understanding, the log file created by OC stops when macOS is actually loading which is when I start to get...

@fryysyd dude that's strange I also have a Nitro+ RX590 (gold edition) and my results are slightly different: Only using WEG (agdpmod=pikera seems optional to me as I see no change with or without), OpenCL results are between 47000 and 49000 (a bit higher than yours) but Metal is more between...

I tried to set the @0,name key to ATY,Orinoco or ATY,Guariba and removed all other keys, so I had only the framebuffer name. Same issue: stuck on a black screen during the middle of the boot. Maybe your question is unrelated to this thread.Do a small research and you should find more...

You mean <key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)</key> <dict> <key>@0,name</key> <string>ATY,Orinoco</string> </dict> with nothing else in device properties, and use WEG + agdpmod=pikera (which I already do)?? I'm confused because...

Thanks now it boots successfully! Little to no significant gain in GeekBench5 (as expected for a RX590 I guess), hard to say as I have a variance of +/- 2000 points betweeen two runs. However I first came here by hoping to get a better power consumption. The monitored power raw for the GPU is...
