10.7: How to get a full Lion install disc for a new MacBook Air or Pro
Authored by: applguy on May 11, '13 11:28:54AM

I've been to quite a few websites trying to glean info on How to get a full Lion Install disk for a MacBook Pro or a MacBook Air (have both).
I found the article posted by Charles S :" Sep 07, '11 07:30:00AM Contributed by: CharlesS" to be the ticket. I was able to replicate everything EXACTLY as he described it with the Terminal App in my Utility folder.
HOWEVER- the only thing I did do differently was I plugged an 8gb USB Drive into a USB port on each machine and did the installation there. Charles reports:
"To avoid messing up your one and only good Lion installation, I recommend getting an external drive big enough to install Lion on. An external hard drive or separate partition is great. A large USB flash drive might work, but I haven't tried it."
The other thing to do is MAKE SURE YOU OPEN A TEXT App (like TextEdit) so that if you do leave the computer- it WILL NOT REBOOT your machine. Make sure you SELECT SAVE for the document you opened and leave that window there from TextEdit to keep the machine from rebooting. I did this late at night, went to bed and the next morning the MacBook Pro/Air were waiting to reboot- BUT HADN'T BECAUSE TextEdit WAITING TO SAVE THE DOCUMENT! Force Quit the Installer (Option/Command/ESC) and your done. I quit TextEdit as well.
Next I copied the resulting folder from the USB Drive to my Desk Top and fired up Lion DiskMaker ( ). Lion DiskMaker makes Lion & Mountain Lion Boot Disks really easy so POINT LION DiskMaker to the newly created folder on your Desk Top to the InstallESD.dmg program. I used the 8gb USB Drive (that's why I saved the contents from the USB Drive to a folder on my Desk Top) that I already had plugged into the MacBook Pro/Air. Lion DiskMaker erases the 8gb USB Drive and creates the BootDrive. It's that easy. I unmounted the Recovery HD drive and the OS X 10.8.2 Base System drive when I was finished. This worked great on my MacBook Pro 13" (latest 2.9ghz i7 non Retina) 2012 model & my MacBook Air 11" (latest 2.0ghz i7) 2012 model.
