If someone else can get it to work, lemme know, I'll add it) Run a sound at login (not boot - for some reason, at least in El Capitan, using Afplay at boot through crontab and LaunchDaemons is not working.This is here for debug purposes, disabling it can be a very bad plan) Disable the boot chime (seriously, I don't recommend this.Using a few techniques I picked up on the interwebs, I've figured out a way to both But there are a few things you can do instead.
