Thanks. I'll try to give it a shot some time during the week... My schedules have been a bit chaotic...

Finally, found time and tested it. Really works. I attached my files if you need it you can look at it.

Note; Before restart remove old nvram.plist and EmuVariableUefi.efi.

Awesome!! Thanks for the files. I'm very excited to give it a try ASAP.

Holy smokes!! It works!! I tested with Clover and OpenCore. I needed to clear NVRAM once before it all started to work, but after that, everything was smooth.

I'm going to have to reassess how I feel about Z390...

Much props to the guys at acidanthera!!!

Working here too (Z390-I).

Can clean up the various scripts that were used to help persist the nvram.plist as well.

Though my CPU is different (and my GPU), we both have a coffee lake processor and a similar motherboard (I have the -E) version. No matter what I do, Catalina 15.1.2 seems impossible to install. I've followed instructions, but no matter what I do when the MacOS utilities menu appears and I select a drive to install to, it boots me back to the MacOS utilities menu saying it failed to write to private. I've tried several USB sticks, ports, and different catalina installations.

Tried swapping VirtualSMC for FakeSMC, Mac Mini SMBIOS and iMac18,2/18,3 SMBIOS. Any idea what I could try? I have no idea how to fix the issue!

Thanks for your amazing guide though, it's gotten me further than anything so far. If I'm forgetting to provide any information please let me know!

Failed to write to private?? I've never heard of this error... Can you please provide a picture?

Did you use Disk Utility to initialize your drive to APFS/GUID?

My bad, I'm being stupid! failed to open file <private> is what it says before spitting out a huge error log.
I'll provide more details when I'm home today. Also, yes - I used disk utility to set it to APFS/GUID. Other disks sadly don't make a difference.

Official idea is coming from the German Hackintosh site. I forgot to mention. Add slide=0 boot arg also. Someone tested it there and he is saying with slide=0 it's much stable without it he is getting sometimes allocation error while booting. Just keep in mind.

I have slide=0 on Clover and OpenCore. The reboots seem to be work fine. I tested about half dozen cold boots and a dozen warm reboots.

On OpenCore, I placed the new SSDT as the first SSDT to load.

Btw could you please share your OC Z390 EFI. I will try to create an OC tomorrow and I want to use it for a base.
