Install Lion as Guest OS on Real Mac.

[willgonz]

So I have a MacBook Pro i7. I would like to install a guest OS of Lion. I am running Lion now, but I need a test environment so I can safely break stuff in the test. Is there a guide?

 

Thanks,

Ok I think I got this to work. First I used VirtualBox 4.1.2 then I followed this guide:

Then I followed this Guide only doing the part of the OSInstall.mkpg I ended up copying his downloadable one and putting it into mine.

It is installing now.

 

Here are the steps:

 

 

Buy the Lion upgrade from the Mac App Store and wait for it to complete its download. Do not launch it.

Start terminal and enter the following

cd /Applications/Install\ Mac\ OS\ X\ Lion.app/Contents/SharedSupport
open InstallESD.dmg
cd /Volumes/Mac\ OS\ X\ Install\ ESD/
hdiutil convert BaseSystem.dmg -format UDRW -o ~/Desktop/Lion.dmg
hdiutil resize -sectors 8636968 ~/Desktop/Lion.dmg
hdiutil attach ~/Desktop/Lion.dmg

Right now you would have 2 disks mounted in Finder, “Mac OS X Install ESD” and “Mac OS X Base System”.

Head into “Mac OS X Base System” and then the “System” directory. Enter the “Installation” directory and deleted the file with an arrow named “Packages”.

Copy the “Packages” directory in the “Mac OS X Install ESD” disk into the same directory where you deleted the “Packages” file previously.

Replace the OSInstall.mpkg with the one from Install Retail Lion on Virtual Box 4.1, Guide on installing Mac OS X Lion on Virtual Box

This copy should take a huge amount of time. Its about 2GB in size.

Eject both drives once the copy is done.

Switch back to terminal and enter the following

hdiutil convert ~/Desktop/Lion.dmg -format UDZO -imagekey zlib-level=9 -o ~/Desktop/Lion\ Install.dmg

Wait for it to do its thing. Once its done, “Lion Install.dmg” on your desktop is a disk image you can either burn to a DVD or restore to a USB drive for a way to boot into the Lion install process to get a clean install.

By clean install, it means using the bootable DVD/USB and then running disk utility to format your system to install Lion.

 

You do not need any Hacks if you're running on a real Mac.
