Solved Stuck after first reboot during Catalina install

[marcoled]

Hi all,
this is my second installation of a Catalina build on my system. I have Ryzen 3600 and RX3700 graphic card. I had a working system running 10.15.3 on OpenCore 0.5.9, but I had some issues with other softwares and wanted to upgrade to the latest Catalina. I followed again all the steps in the guide and have a working 0.6.3 USB bootable installer. I reach the installer no problem, I can use Disk Utility and start the installation, but after the first reboot (and choosing Mac OS Installer instead in OC) and a bit of loading, I reach a stop point. Attached is an image of where I cannot get out or continue. The installer basically says Mac OS cannot be installed in this machine. I can share the log from the installer if needed, but maybe there is a quick easy fix of something I might have overlooked?
Thanks for the help!
Cheers,
Marco

and here is my EFI.
I tried several solutions suggested for other issues, including changing the EnableWriteUnprotector, RebuildAppleMemoryMap and SyncRuntimePermissions but with no luck. The strange part I believe is that it boots correctly, loads the first part of the installer but instead of continuing after the first reboot, shortly after the apple logo I get the error message above... could it just be a problem with the installer itself? I'll try making a new USB, redownload the installer and see...
in the meantime though, any help is greatly appreciated
Thanks!

Solved. it was as simple as changing the SMBIOS to iMac18,3 instead of iMacPro1,1. Thanks Reddit.
