Hay un MacFUSE implementation of procfs. Con él, se puede obtener el mapa de memoria de la siguiente manera:
cat /proc/PID/task/vmmap
Mirando el source code, parece que se trata de utilizar la Mach virtual memory interface para obtener el mapa de memoria del kernel.
Aquí está la aplicación para la vmmap

Esto se ve muy bien, probablemente lo acepte una vez que ejecute algunas pruebas al respecto. – Sufian
