Everything works except sleep.
If you want to use attached EFI folder you need to generate your own SMBIOS SN. I recommend to use MacPro7,1.

Hi Anti,

First I want to say INFINITELY thank you for posting your EFI. I finally managed to get the system installed after being stuck for more than a week.

My system is 2700X / X570i Aorus Pro Wifi / MSI 5700 XT

Everything is working except the BT/WIFI card. My MB (Aorus x570i pro wifi) had one on board that I swapped with another confirmed supported (Broadcom BCM94352Z DW1560 6XRYC).

Could you tell me if in your EFI you added any setting/kext to disable the onboard card?

Do you have any suggestions about what could be preventing it to work properly?

Seems like changing the SMBIOS model to "iMac9,1" fixes it and in some cases also enable sleep/wake.
You mean iMac19,1? Yeah I'm on it, no sleep and the shutdown still doesn't work. (I have tried removing all the USB devices as well)
About the 5/10 min idle reboot, I've "fixed" with amphetamine.
