Please tell about efi. Are you using my uploaded EFI. If yes then reples wireless kext with this which is for catalina. And remove my usb mapping and add injectallusb
I am using yours, I went in and changed it to point towards my iGPU.
This is all pretty new to new so I hope that I am doing it right. I have removed the USB map, and added the inject all and the airport kext. After that I did a shift/ctrl + r in propertree and then saved the plist. I have it attempting another install now. I didn’t see another Wifi kext to remove when I added the one you posted.
After booting the usb installer I went in to disk utility and formatted the nvme drive to APFS and pointed the install to it. Takes about 90 minutes for it to install so I will check back in a bit. Is my assumption correct that if the install goes right then it should reboot in to the Catalina install where I can finish the post-install configuration and not the usb installer?
Thanks again for the help
