I'm a bit confused as to what the structure of the installation USB should be. Mine has the "Install macOS Catalina" file (8.09GB) which I copied to it, and an "EFI-Backups" directory that appears to be empty, which looks like it was added when I ran Clover 4961. I manually added Clover Configurator and MultiBeast (9.20) so that I'd have some utilities when I got up and running, and I added Lilu.kext, RealtekRTL8111.kext and WhateverGreen.kext to the root of the USB as well. I can get to the installer no problem, but after 20 minutes or so it does a reboot, and after about a minute continuing the installation the system freezes, with a bunch of horizontal pink lines on the screen.
OK, I'm an idiot. I used Clover Config. to mount the EFI partition, then went to the kext/other directory and added the 3 kexts plus downloaded and added FakeSMC.kext.
After doing that I was able to install no problem. However, MultiBeast failed. If I look at the EFI folder on the Catalina drive it only has an "Apple" folder.
Did I miss a step somewhere?
