Ensure Wake for Network Access Is Disabled

LowLevel 1Automatedmacos

Description

This feature allows the computer to take action when the user is not present and the computer is in energy saving mode. These tools require FileVault to remain unlocked and fully rejoin known networks. This macOS feature is meant to allow the computer to resume activity as needed regardless of physical security controls.

p=$(/usr/bin/profiles -P -o stdout 2>/dev/null | /usr/bin/grep -c '"Wake On LAN" = 1')
