Ensure NFS Server Is Disabled

MediaNivel 1Automatizadamacos

Descripción

macOS can act as an NFS fileserver. NFS sharing could be enabled to allow someone on another computer to mount shares and gain access to information from the user's computer. File sharing from a user endpoint has long been considered questionable, and Apple has removed that capability from the GUI.
