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

Hello @skroutz999,

Some comments:
  • Issue 1:Getting stuck at Apple logo when booting through OpenCore.
    • We should Reset NVRAM from the OpenCore Picker by pressing <spacebar> and selecting "Reset NVRAM". When the computer reboots (automatically), press F12 at BIOS Splash Screen to select USB flash disk. Then at the OpenCore Picker, select the macOS SSD.
  • Issue 2: Laggy behavior via Clover.
    • Please try resetting NVRAM (pressing F11 at Clover Boot menu will clear NVRAM)
    • Also try cold boot (shutdown system and flip power switch on PSU to OFF for 10 seconds)
Yes I reset NVRAM from the OpenCore w/o luck. After that I couldn't boot even w/o usb. It was booting from my 2nd ssd at win10. With F12 I couldn't also boot and windows was loading again. So I tried a cold boot. Got into Bios and loaded optimized settings. Then restart and put the settings from the guide once again. Then I was able to log back to macos. But with lag again. I tried also resetting NVRAM from Clover boot menu by pressing F11 but again system is laggy. Very strange things...
 
I think it should be pin 3 and 5 according to post #16393 and I've successfully done it with my Alpine ridge.
Hello @oreoapple,

If you hold the GC-Alpine Ridge vertically so that the gold PCI pins are pointing down towards the floor, then which two pins are you connecting?
  • The top and middle pins?
  • The middle and bottom pins?
 
I think that I won't get away from a fresh installation this time. CaseySJ do you suggest to try a fresh installation with Opencore this time? Is it a better method than Clover? Do we have enough succeed cases?

Strange indeed...
  • What is your BIOS version? Have you tried F9g in which CFG-Lock is unlocked by default? I've been using this version ever since it was posted to the beta website (TechPowerUp?). It's completely solid in my experience.
  • If you prefer to stay on the BIOS that is already installed, then try a CMOS Reset by shorting the two designated pins on motherboard. BIOS parameters will need to be configured once again. And if MSR 0xE2 had been unlocked before, it will need to be unlocked again (switching to F9g avoids having to unlock MSR 0xE2).

Im on F9b for a long time now on my both systems w/o issues. But if you suggest F9g then I can try it out.

We have plenty of successful cases with OpenCore on both Z390 and Z490. In fact, 100% of Z490 installations are done with OpenCore.

If you have a spare SSD, then yes I would certainly recommend a fresh installation. If you create the OpenCore 0.6.0 EFI folder on a USB flash disk and unlock MSR 0xE2, then you can install Mojave or Catalina by following the Z490 Vision D guide (yes, you read that right) but skipping Steps 4, 5, 6, 7. The Z490 guide is located here:
If you decide to do this, feel free to compress and upload your OpenCore EFI folder. You may in fact send it via Private Message (so you don't have to remove serial numbers). I can double-check it before you begin.

Yes I want to try it out! I hope some bugs I had to be fixed with the new method. I will start at the morning and will let you know CaseySJ! I hope everything goes well! :)
 
Middle and bottom
@xtreem.p,

Looks like I gave you some bad information! Apologies...

When holding the card vertically with the gold pins pointed down, we need to jump the middle and bottom pins on the GC-Alpine Ridge.

Have you already tried that?
 
So if I want to use it on a X299 board, what should I do with SSDT? Seems like PCI root path can be an issue according to post #23790...
