Sonoma installing problem

Thanks to everyone and @UtterDisbelief. I will try to follow your indication.

Well if, as @trs96 explains above the iGPU can be made to work then review your Device Properties for it as it has the word "headless" in there which clearly leaves no GPU to output through.

Besides the "Headless" Comment he also does not seem to have edited the Device Properties as specified in @trs96 linked thread. You are supposed to get the EDID information from windows and then amend your config.plist.

I was stuck at that point as well and pulled my hair off fighting through all possible suggestions from the guide and finally solved by a rather simple and unexpected issue: When the OS wanted to take over there suddenly was no USB port to recognise. Workaround: Using a different USB port and the install continued. Maybe worth a trial.

Thanks, I confirm that I also found the USB problem, on the 2.0 it works, the 3.0 doesn't. For the rest I have very little time to dedicate to the project. I stopped with the 590. Since it was my first installation I switched to an MSI Z490 A, I'm also having problems. However, I'll try in some spare time. Thanks everyone for the advice.
