UniBeast apfs.efi error

[Mitcht79]

You must select GUID partition but it's only available if you select in the view options at the top left corner of the Disk Utility window, "Show Only Volumes". So simply select view - show all devices, then select the actual drive you're trying to reformat, then when trying to erase, you should have the option to choose a partition scheme.

This fixed my

"Copy of 'apfs.efi' failed" error

Thanks

It's not a bug it's how macOS operates, if the Finder has the folder open UniBeast can't write to it.

How do you prevent the EFI partition from auto mounting during the unibeast usb creation?

Thanks a million! I had the exact same problem as OP. Seems so obvious now

Same problem for me, I will try again tonight and make sure the Finder window is closed.

EDIT: I tried again with a new USB-stick and still the same. I'm on Catalina on my MacBook so I thought maybe it's a compatibility issue with Unibeast so I tried Mojave instead of High Sierra and that worked fine. Not sure why the High Sierra Unibeast won't work but the Mojave will.

I'm having the same issue. I've tried:
1. sudo diskutil partitionDisk USB-Device GPT JHFS+ VOLUME-NAME R
2. make sure it's partitioned in GPT

Here is what I see after executing diskutil command:

/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   2:                  Apple_HFS USB                     15.0 GB    disk2s2

Here is what I see in Disk Utilities:
