<< Solved >> How to copy the EFI from Unibeast to EFI partition?

[oliversl]

Hi,
when I boot my Mac installation using the Unibeast usb disk, my AMD RX580 works fine, but after running Multibeast and boot from the hard drive, it does not work.
I wonder if I can just copy the files from the EFI partition form the Unibeast USB to the EFI partition in my hard drive. Will it work? Many thanks!

Yes, you can copy paste the EFI from the USB to your hard drive's EFI system partition.

Or you could upload your MultiBeast screenshot to let people diagnose.

I will copy the EFI partition form the USB to my hard drive. I re-installing it so right now I don't have the multicast info.
