#############################################

## Requirements:
## 33.5GB available storage for temporary files (1.5GB) and virtual disk images of base system (2GB), installation (8GB), and target (22GB)

## The following has to be installed manually:
## VirtualBox
## dmg2img (from package manager for Linux or http://vu1tur.eu.org/tools/dmg2img-1.6.6-win32.zip for Windows)
## curl (from package manager for Linux or https://bintray.com/artifact/download/vszakats/generic/curl-7.62.0-win64-mingw.zip for Windows)
## On Windows: Place dmg2img executable and curl executable and dll in working directory
## After the first part of the installation, EFI drivers will have to be downloaded manually with Safari

## The following will be downloaded automatically:
## macOS Mojave 10.14.1 BaseSystem.dmg from Apple - on the host, to bootstrap the VM
## macOS Mojave 10.14.1 BaseSystem.chunklist InstallInfo.plist AppleDiagnostics.dmg AppleDiagnostics.chunklist BaseSystem.dmg InstallESDDmg.pkg from Apple - on the VM

# On the host terminal, create a VirtualBox virtual machine:
vmname="Mojave"
VBoxManage createvm --name "${vmname}" --ostype MacOS_64 --register

# Create the macOS base system virtual disk image:
curl 'http://swcdn.apple.com/content/downloads/35/53/091-93471/ff5kp0aiow1d87t494xp5twbugymnlvz16/BaseSystem.dmg' -o BaseSystem.dmg
dmg2img BaseSystem.dmg BaseSystem.img
VBoxManage convertfromraw --format VDI BaseSystem.img BaseSystem.vdi

# Create the target virtual disk image:
storagesize=22000    # minimum 22000
VBoxManage createmedium --size="${storagesize}" --filename "${vmname}.vdi" --variant fixed

# Create the installation media virtual disk image:

# Shut down the virtual machine
# On the host terminal, erase the temporary files and settings:
VBoxManage list hdds | grep -B4 "Install\|Base"
# "close" the UUID of all unused virtual disk images:
VBoxManage closemedium <UUID-of-BaseSystem.vdi>
VBoxManage closemedium <UUID-of-Install....vdi>
rm BaseSystem.dmn BaseSystem.vdi Install*.vdi
