MacBinary is the protocol currently used on MAUG for transferring binary
files to/from a Macintosh.  A MacBinary receive is triggered by doing an
XMODEM receive of a file that has certain magic numbers in several of the
bytes comprising the first packet.  However, it is possible (though unlikely)
for a non-MacBinary file to have the same numbers in the same places.  The
"Disable MacBinary format" option is thus useful when you are transferring
non-Mac binaries and don't want a MacBinary receive triggered by accident.
