Did you ever figure it out? I have the same issue on my Z97-A. Native NVRAM works fine in Clover but does not in OC. I guess I could always enable emulated NVRAM to work around this.

No, I never did figure out the issue. I did fix the problem by wiping the drive clean and then reinstalling OC/Catalina. Everything now works as it should. It's stable. OS updates no problem, as the June OC update.

I kind of have the same issue with my Asus Z-97k. NVRAM emulation not working with opencore. I will try the fresh install

I have the same motherboard but mine is freezing up to a black screen; this is typically caused when it's been idle for a bit but also occurs during running a game (GRID Autosport via Steam) or after the game ends and sometimes while working on anything (chrome, terminal, etc).

Would you be willing to upload/share your EFI folder?

I switched MB's but I think the attached files were my last functional OC version 0.5.8.

Good Luck.

Thank you! This helps a ton! A couple questions;
You've the AirportBRCMFixup kext being loaded. Is that for a dedicated wifi card? The UD3H doesn't come with any wifi capabilities...

Thanks again! The USBX file will surely help :)

Correct. I added a PCIe Wi-Fi card with a Broadcom chipset. It has both Wi-Fi and Bluetooth capabilities.
