@Arty Hi there, I am having the same issue, can you kindly elaborate on how exactly you did it. Thanks
I don't remember exactly, but I think it went that way:

1. Installed everything
2. Restarted with USB, which ran USB's version of Clover
3. Booted into OSX, ran EFI Mounter to mount partitions
4. Copied Clover from USB to hard drive's EFI partition overwriting all files

When trying to install Nvidia Graphics Fixup Multibeast fails to mount the EFI partition, mounting it manually on /Volumes/EFI works just fine. If the partition is already mounted Multibeast unmounts it and then fails with the same error.

-------------------------------------------------------
  • macOS version: 10.3.4 (build 17E202)
  • MultiBeast version: 10.2.0
  • MultiBeast choices:
Drivers > Graphics > Nvidia Graphics Fixup
  • Destination files system type, HFS+ or APFS
Root partition is APFS and EFI partition fat
  • MultiBeast.log contents
04/25/18 21:12:43 - Mounting EFI
04/25/18 21:12:43 - Mount of EFI partition failed. Exiting.
  • install.log contents for the choices that you are installing
No multibeast related entries in /var/log/install.log

I ran in to the same problem. I tryed to mount EFI with EFI Mounter v3.1 and ran MultiBeast again, it worked out and the mounting error was gone. Maby that could help you.
