Now I really don't know what to do. I had an EFI created with OpCore-Simplify.

After hanging at [EB|LOG:EXITBS:START] I disabled DevirtualiseMmio.

The computer boots and I can start the installation. However, it sometimes takes several minutes between clicking on "Install macOS Sequioa" and the next dialog. Then the installation starts and runs quite quickly, until "About 12 minutes to go". Then the computer freezes. Nothing works anymore.

Of course, I always deleted the NVRam. I checked BIOS-Settings multiple times. I created a USBMap.kext using USBToolBox on Windows. That didn't work. Only with USBToolBox.kext and UTBMap.kext it didn't work either. Not without USB mapping either...

I also worked through "Dortania Troubleshooting".

By the way, I deactivated the Bluetooth and WiFI controllers in the BIOS, as they would not be supported anyway.

Can someone of you please take another look at my config.plist? That would be very nice.
