I'm really really lost.
I have Mojave working with some sleep/wake problem but that's fine. Everything works as it should. Performance is satisfying.
I've installed Catalina a dozen times but I run into the same problem time after time.
I can not mount an Efi folder on Catalina. Not the one on an USB drive not the one on a Sata disk. I can mount them in Mojave but not in Catalina. I only can boot Catalina in safe mode due to the fact that my graphics card is not properly installed. My Efi's are attached.

So first problem: How can I get the EFI partition mounted in Catalina so I can use Clover Configurator to edit my config.plist
Besides that challenge I'm not getting progression on getting the RX570 to work. I've tried this guide and this guide on AMD Graphics cards and framebuffers. Nothing seems to put me on track.

All attached screenshots are from the Mojave boot.

What am I doing wrong, thanks for any support, help and advice!

use clover configurator to mount the EFI drive
you have posted several useless pictures proving that you have no problem and no picture showing your actual problem
if your config works in Mojave it has to work in Catalina as well

you cannot? because of you do not know how to do it? are you having any specific error or shall i just simply guess? just install newest clover configurator and give your password when prompted on the efi mount

Terminal tells me:
Volume on disk0s1 failed to mount
If the volume is damaged, try the 'readOnly' option

Clover Configurator does not give me a message back why it is not possible and Efi Mounter 3.1 exits with error -1000.

So, yes, you are right, I don't know how to mount it, sorry @theruck
