Our popular WinTD chess tournament pairing software is available for Macintosh computers running OS X. It will run on any OS X 10.5 (Leopard) or later, and the features of the program are essentially identical to those of the Windows Version of WinTD 4.2 (see Features for details).
Please see the Prices and Ordering page if you are interested in ordering a copy of WinTD for Macintosh, and feel free to contact us if you have any questions.
