Rocksmith Runner

#!/bin/bash
# This fixes keyboard issues in Rocksmith when Karabiner Elements is installed

# Stop/start procedure taken from Karabiner sources:
# https://github.com/tekezo/Karabiner-Elements/blob/master/src/share/launchctl_utility.hpp
# enable/disable commands throw errors left and right, but somehow work.
# I do not dare change the commands.
