Preparation

• Shutdown Mac Virtual Box

• Create new 5Gb LionInstaller HDD on Virtual Box
  
• Boot into Mac Virtual Box
  
• Format the new drives naming them Lion and LionInstaller
  

 

LionInstaller

NOTE:

• CODE sections are commands type on Terminal
  
• QUOTE sections show snippets of text file
  

 

• Mount Lion Image (InstallESD.dmg) to Virtual Box DVD Drive
  

cd "/Volumes/Mac OS X Install ESD"
open BaseSystem.dmg

• Using Disk Utility, restore BaseSystem.dmg to LionInstaller
  

cp kernelcache /Volumes/LionInstaller/kernelcache
cp mach_kernel /Volumes/LionInstaller/
sudo vi /Volumes/LionInstaller/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

<key>Kernel Cache</key>

<string>\kernelcache</string>

sudo rm /Volumes/LionInstaller/System/Installation/Packages
sudo cp -R Packages /Volumes/LionInstaller/System/Installation/Packages
cd /Volumes/LionInstaller/System/Library/CoreServices 
sudo touch ServerVersion.plist
cd ~
cp /Volumes/LionInstaller/System/Installation/Packages/OSInstall.mpkg .
pkgutil --expand OSInstall.mpkg OSInstall
vi OSInstall/Distribution

var minRam = 1024;

 

function isVirtualMachine(){

return false;

}

 

function isSupportedPlatform(){

return true;

}

 

pkgutil --flatten OSInstall OSInstall.mpkg
sudo cp OSInstall.mpkg /Volumes/LionInstaller/System/Installation/Packages/OSInstall.mpkg
rm -rf OSInstall*

 

Create a kexts folder in LionInstaller and copy:

• nullCPUPowermanagenent.kext
  
• KextHelper.app (Download from http://cheetha.net/)
  

 

 

Installation

• Shutdown Virtual Box
  
• Disable EFI
  
• Mount HackBoot Lion ISO to Virtual Box
  
• Remove Snow HDD
  
• Start Virtual Box. It will boot HackBoot. Select LionInstaller
  
• Run through installer
  
• After the installer completes, restart into Lion using HackBoot
  
• Delete /System/Library/CoreServices/PlatformSupport.plist
  
• Using KextHelper install nullCPUPowermanagenent.kext
  
• You can now shutdown. Enable EFI and remove LionInstaller and HackBoot Lion.
