Im having trouble creating an installer drive with both the Unibeast 8.1.0 and 8.0 all of a sudden. It keeps giving me an error saying "Copy of apfs.efi failed".

Ive tried downloading new copies of High Sierra Installer and Unibeast 8.1.0 and 8.0.0 from this domain but havent had any luck. Has anyone run into this problem and been able to solve?

My second problem is when i was installing high sierra, in disk utility, after i format my samsung evo850 ssd pro, it caused 2 additional partitions that are unmountable and cant be erased. their sizes are very small but is somehow causing the drive to not show up as a selectable drive to install the macOS on.

Has anyone run into these problems and been able to solve?
