Facio is a free GUI for computational chemistry softwares (TINKER, MSMS, Firefly, Gamess, MOPAC and Gaussian).
It will be helpful to your study and research on theoretical chemistry.
Current Version : 25.1.2 (released on July 17, 2023)
For Mac OS X (10.6 or later) and upto macOS 10.14 Mojave,
you can run 32-bit ver. with Wine (stable 5.0)

Facio is named after a Latin verb "facio" which means "I make". So, please pronouce "c" in Facio as [k] as in cat.
This software is indispensable to FMO (Fragment Molecular Orbital) method of Gamess
because it is the only GUI for FMO-specific input and output.
