I installed macOS Big Sur with this EFI but my type cover and trackpad were not working. I suspected it’s because I installed Big Sur, so I installed Catalina on a separate APFS volume to not delete the original Big Sur installation, doing this fixed my USB C over HDMI as it wasn’t working on Big Sur but my type cover still wasn’t working. It worked in the OpenCore boot picker but when booting the OS the keyboard would stop responding. I believe there were different type cover models that were sold, the one I have is an Alcantra type cover if that’s somehow relevant to this. I haven’t modified the EFI at all from when I downloaded it, I have no clue why it wouldn’t work.
