The beta version of ConceptDraw 6.1 for Mac OS X is available for free download and testing to registered users of ConceptDraw 1.5.8 and earlier.

The final version of the diagram- and flowchart-creation application will be demonstrated at Macworld Expo in San Francisco from 9-12 January.

Developed by CS-Odessa Systems, the application has been carbonized for Mac OS X.

Gregory Zhukov, president of CS-Odessa, said: "It's a great day for us. The new features in Mac OS X give a new level of power to the developer, allowing them to create much more powerful, efficient and stable applications.

“We are proud to have supported Mac OS X in its early days, and to provide Mac OS X users with comprehensive and convenient tools for their everyday work."
