Is there a HIARCS chess product for the older Mac Classic OS 7, 8 or 9?
Yes, HIARCS was the first world class chess program to support the Macintosh. We began supporting the Macintosh as far back as 1995. You will find details our last product Hiarcs 7 for Macintosh here which is still available from some retailers. We now support Mac OS X and no longer support the older Mac OS Classic 7, 8 or 9.
