The Mac version of ESSENTIA duplicates
most of the features of its Windows counterpart with only a few exceptions. The main
difference is the lack of an analysis engine in the Mac version. "NOW", the
engine used in the original ESSENTIA, is a DOS based program and could not economically be
converted into a Mac format. The stand-alone "NOW" program has also been
replaced by another master-level program that can run on Mac machines. The one million
game ESSENTIA database appears on the CD in ChessBase (tm) format. This allows users with
the Mac edition of ChessBase to access the database directly from the CD-ROM. |
