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

Puzzling...

• Which version of BIOS are you running? F9g, F9i, F9j?
• What is the make/model of your USB flash drive?
• Which USB port is it connected to?
• Other than macOS, which other operating systems are installed?
• Have you tried CMOS Reset (which requires configuring BIOS parameters again, starting with F7 to Load Optimized Defaults)?

Using BIOS F9g
Using a MicroCenter USB 3.1 32GB stick
Using Blue USB 3.0 Port
No other OS's installed
No on the CMOS reset.

I was going to try another USB still and different port next.

After trying (a) another USB, (b) different USB port, and (c) CMOS Reset, if the problem still occurs then please compress the entire EFI folder (remove serial numbers from config.plist) and post. I will try to boot my system with an exact copy of your EFI (but with my serial numbers).

Please try a cold boot first. If that does not solve the problem, then CMOS Reset!

I'm still on F9j.
What if I go back to F9i?
Will flashing firmware resets CMOS automatically?

Please try build 1.0.6.

New EFI partitions will automatically appear in the window.
Leave the window open and plug a storage with EFI Partition
Mount/Unmount too (ex: if you unmount from EFI Agent/OCC..)
Hope this version solves Windows EFI's issue

In boot-args please check if you have agdpmod=pikera

Do i need to put something in between?

No

@CaseySJ Do you know of any issues with enabling CSM support? I cannot boot with it on, but I think it will help me with my display issues (sometimes one screen will stay off when the displays sleep - right now the computer itself is set to never go to sleep, but the issue is the same when that is enabled). Here is a picture of the opencore boot log:

Both displays are connected via displayport to the rtx 580.

Your boot-args are correct.

Please describe exactly what happens when you boot the system.

• Does OpenCore Picker appear?
• If so, when you select macOS SSD, then what happens?
• You can also press CMD-V at the OpenCore Picker to enable "verbose" mode. Then select macOS SSD.

Some questions:

• Which version of macOS are you running?
• Which version of BIOS is installed?
• What exactly happens when CSM Support is enabled? "I cannot boot with it on" is, unfortunately, not descriptive enough!

1.0.6 working great for me.
Nice feature for identifying the respective EFI.
Thanks.

Thanks for the feedback
Do you have Windows or Linux beside your macOS ?
