Sé que esta es una publicación bastante antigua, pero acabo de encontrarla en Google mientras buscaba algo similar (en su mayoría solo quería listar las fuentes activas a través de Terminal). Terminé recordando que las fuentes activadas se enumeran en Información del sistema que se puede extraer del comando system_profiler
Dicho esto, aquí está el comando para extraer información de la fuente de system_profiler:
system_profiler SPFontsDataType
Eso es todo. Debe devolver una lista enorme de datos de fuentes en el formato de:

Description: Monotype Drawing Office 1982. A contemporary sans serif design, Arial contains more humanist characteristics than many of its predecessors and as such is more in tune with the mood of the last decades of the twentieth century. The overall treatment of curves is softer and fuller than in most industrial-style sans serif faces. Terminal strokes are cut on the diagonal which helps to give the face a less mechanical appearance. Arial is an extremely versatile family of typefaces which can be used with equal success for text setting in reports, presentations, magazines etc, and for display use in newspapers, advertising and promotions.
