Updated for Catalina and mainly for Music Sequencing https://github.com/matthewcosgrove/macos-bootstrap

	#!/bin/bash

	# STEP 1: Mount bootable USB and clean up disks
	# IMPORTANT: Catalina now introduces a different approach to Disks/Volumes: https://eclecticlight.co/2019/12/17/how-clean-re-installs-change-in-catalina/
	# Erase everything for a proper clean install and then create a new GUID Partition Apple_APFS volume (equivalent to https://www.youtube.com/watch?v=PqfqcwmHowc&ab_channel=AjudaAqui)
	# Can all be done through Disk Utility rather than terminal diskutil. You just need to create at least one volume otherwise the installer will not see the disk

	# STEP 2: Install Catalina from bootable USB

	# STEP 3: Download this gist from UI of GitHub "Download Zip
