Hello,
The Apple EFI packages released in the last few months seem to have a slightly different PBZX format which causes AnyToISO to crash as such:
Unpacking...
pbzx_inflate_stream: the header is not 7zXZ
CPIO format: 0
Reading archive...
Unexpected end of of cpio archive
Extracting...
Inconsistent data (size mismatch)
Here is a package sample link.
