How to Create OS X Lion DVD Install Disc

With the arrival of the new OS X Lion, Apple pushes on with the process of ditching retail cases and installation discs. Though you can buy an USB install pen, it's clear Apple sees the internet as the main delivery system - the new Macs can even enter recovery mode by booting from the internet.

However, not everyone has easy access to unlimited high-bandwidth internet connections, and that's why lots of people will still prefer keeping an OS X Lion Install DVD handy.

So, how do you create a DVD install disc for OS X Lion?

Download the OS X Lion install file
  1. With the App Store closed
  2. Press and hold the Alt key and open the App Store
  3. Go to OS X Lion download (still pressing the Alt key) and you'll see the "installed" option is replaced by a "Buy now" button. 
  4. Click "buy now" - (and you can release the alt key now)
  5. Enter your login data
  6. You'll see the usual: "You've already bought this item", and press ok to dowload it again.
  7. Wait for the download to end... (the Install Mac OS X Lion package will be placed on the Applications folder)

Convert the OS X Lion Install File into a Install DVD
  1. Right click on the install file and choose Show package contents
  2. Copy the InstallESD.dmg in the /Contents/SharedSupport/ folder to another location
  3. Use Disk Utility (in the Utility folder) to burn the extracted image to DVD

And it's done. Installing from DVD can take a long time, so be patient...
