Also, this version appears to be one that was "right in the middle" of some changes to the Stonewall code... Perhaps 15.4 will be compiled for the Mac soon, and you can try it again... but remember, Crafty is a "null-mover" which means slow computers are really incompatible with it, since it was "designed" on a P6/200. If you slow it down by a factor of 10, you can expect null-move problems, and in the Stonewall, there is *plenty* of opportunity for them...
