If there's somewhere I can email you the file, happy to do so. Seems like this site didn't like the pics I was trying to upload.
What about this...
I was never able to copy ED's EFI folder over to my drive, because there was no way to mount my Mojave drive, but I have an external case I can put my Mojave drive in.
Last time I looked, there were multiple EFI folders on the Mojave drive. Can you point me to the specific location of where a legit EFI folder like ED'S should be on the Mojave drive, and I can delete the others? Maybe that's part of the problem? Duplicate EFI folders/kexts etc?
