Hey @MaLd0n
Thanks for this amazing forum, and all the good work you are doing to help Hackintoshers worldwide. I am facing a problem, trying to help a friend install Catalina with your EFI folder (EFI OpenCore Serie 300.400.zip). His hardware is:
Gigabyte Z490M Gaming X motherboard with latest F20 BIOS revision
Intel i7 10700K processor
Samsung 1 TB M.2 NVME drive
32 GB Corsair Vengeance DDR4 3200 RAM
He has Windows on his machine, and he is trying the Windows method from the Dortania website, to create his installer USB.
The problem is that we are (at best) able to get the USB to boot, but when we choose the installer option, we get the Apple logo with the progress bar below it, and it disappears after about 40% progress, and then the screen goes black. Nothing happens. We have tried EFI folders from other people who have successfully installed Catalina on their Z490 boards, but somehow are getting stuck at this point.
We are hoping that you will be able to help us out of this problem and get Catalina installed on my friend's machine.
Thanks in advance...
