HIARCS Chess Software for Mac OS X

Sigma Chess GUI and HIARCS were the chess GUI and engine of choice from Mac OS 10.4 until Mac OS 10.6. The Sigma Chess GUI is not supported under Mac OS 10.7 or later due to Apple dropping Rosetta support for PPC applications. You can read about our older Sigma Chess HIARCS and Junior products here.
