for the changed script.

You might have to reboot your Mac after Downloading High Sierra in the AppStore,

in case the first hdiutil attach ... step fails.

* (Create install ISO with following script:)

#!/bin/bash

# Mount the Installer image

hdiutil attach /Applications/Install OS X El Capitan.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

# Create El Capitan sparseimage of 7316mb with a Single Partition - Apple Partition Map

hdiutil create -o /tmp/ElCapitan -size 7316m -layout SPUD -fs HFS+J -type SPARSE

# Mount the El Capitan sparseimage

hdiutil attach /tmp/ElCapitan.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

# Restore the Base System into the El Capitan Blank sparseimage

asr restore -source /Volumes/install_app/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase

# Remove Packages link and replace with actual files

rm /Volumes/OS X Base System/System/Installation/Packages

cp -rp /Volumes/install_app/Packages /Volumes/OS X Base System/System/Installation/

# Copy El Capitan installer dependencies

cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/OS X Base System/BaseSystem.chunklist

cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/OS X Base System/BaseSystem.dmg

# Unmount the installer image

hdiutil detach /Volumes/install_app

# Unmount the Base System image

hdiutil detach /Volumes/OS X Base System/

# Optimise Sparseimage Size

hdiutil compact /tmp/ElCapitan.sparseimage

hdiutil resize -size min /tmp/ElCapitan.sparseimage

# Convert the ElCapitan spareseimage to ISO/CD master

hdiutil convert /tmp/ElCapitan.sparseimage -format UDTO -o /tmp/ElCapitan.iso

# Rename the ElCapitan ISO image and move it to the desktop

mv /tmp/ElCapitan.iso.cdr ~/Desktop/'EC 10.11.0.iso'

# Delete ElCapitan.sparseimage file

rm -f /tmp/ElCapitan.sparseimage

* Copy resulting ISO to VM host

* New VM, OSX El Capitan (or whatever), ...

* Tell the VM it's a Mac (replace 'El_Capitan' with your VM name):

VBoxManage modifyvm 'El_Capitan' --cpuidset 00000001 000306a9 04100800 7fbae3ff bfebfbff

VBoxManage setextradata 'El_Capitan' 'VBoxInternal/Devices/efi/0/Config/DmiSystemProduct' 'MacBookPro11,3'

VBoxManage setextradata 'El_Capitan' 'VBoxInternal/Devices/efi/0/Config/DmiSystemVersion' '1.0'

VBoxManage setextradata 'El_Capitan' 'VBoxInternal/Devices/efi/0/Config/DmiBoardProduct' 'Mac-2BD1B31983FE1663'

VBoxManage setextradata 'El_Capitan' 'VBoxInternal/Devices/smc/0/Config/DeviceKey' 'ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc'

VBoxManage setextradata 'El_Capitan' 'VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC' 1

* Mount ISO, install (Create Partition with Utilities Menu -> Disk Utility -> Erase)

* Set resolution via VM's EFI:

VBoxManage setextradata 'El_Capitan' 'VBoxInternal2/EfiGopMode' <N>

// <N> can be one of 0,1,2,3,4,5 for 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1920x1200

- Apparently in VirtualBox 5.2.0 and newer you can set a custom resolution, like

VBoxManage setextradata 'El_Capitan' 'VBoxInternal2/EfiGraphicsResolution' '1920x1080'
