Partially automatable script to get Catalina Beta 6 up and running VMware Fusion 11.1.1 using a physical Mac and USB stick
#!/bin/bash
####
#
# Prerequisite: You must have a disk image containing the "Install macOS Catalina Beta.app" for beta 6
# (installinstallmacos.py generates a nice one)
# The disk image must be reachable on an smb share from the final vm
# You must extract the kernel from inside the Core.pkg in InstallESD.dmg located in "Install macOS Catalina Beta.app" and put it on the root of the USB drive
# Pacifist from https://charlessoft.com is indispensable for this operation
# And you must replace a few VARS down below with values of your own: PATHTOBASESYSTEM, PATHTOBASESYSTEMCHUNKLIST, PATHTOUSBSTICK, SHAREUSERNAME ,SHAREHOST, SHARENAME, PATHTOINSTALLINSTALLMACOSIMAGE
#
# run the script with
# sudo bash Beta6.sh
#
###
#!/bin/bash
# Replace VAR values as needed
