to produce chess software that is Mac-compatible?  The new CT Art 4.0 is out, and I want it.  But nooooooo, I must be punished for not buying a crappy Windows product.  

Can anyone explain this?  It's not as if chess programming is all that complicated, compared to graphic design, or whatever else.  

It's time for Mac-using chess players to rise up.

If you have an Intel-based Mac and Boot Camp/VM Fusion/Parallels you can use PC software. THIS ... in my opinion ... is the most viable way to get to good chess apps. (I have an iMac and VMFusion and use ChessBase and Fritz.)
