Firefly for Mac OS X pages

The official Firefly Logo


As of February 23, 2009, Firefly team is proud to announce the availability of the first official release of the Firefly package for Mac OS X/Intel platform.

List of some key features:


The Firefly for Mac project was initiated by Thomas Patko in a effort to bring the excellent Firefly ab-initio software to the Mac platform. It was made possible by extensive collaboration with the main Firefly project team and tireless beta testing and suggestions from Nick Greeves. Although Thomas is the major developer of Mac-specific code, as well as primary documentation contributor in the "Mac Port" at present in this initial release, the primary goal of the project is to develop the Mac edition continuously to make it more accessible and easy to use for chemists worldwide operating the Apple Macintosh platform.

The best method to accomplish this is to have an active collaborative environment where users are free to request features, report any bugs, and to have multiple contributors to the codebase for the "Mac Port".

The most recent official version of Firefly for Mac OS X is version 8.2.0

Unfortunately, MacOS starting from Catalina stopped supporting 32-bit applications, so currently it is not possible to run Fierfly there. Please, consider using earlier versions of MacOS or other operating systems on a virtual machine.

Some hints


Firefly team is grateful to all beta testers. Our special thanks to Nick Greeves and Lyndsey Vernon, University of Liverpool. This Mac release of Firefly would not be ever possible without efforts and constant development made by Thomas Patko, who was the main driving force behind Firefly for Mac project.
