A lot has been said about Lion being delivered purely as a digital download rather than physical media.
Also, with a new operating system, like a lot of people I prefer to do a clean install rather than an upgrade. It's a great way to spring clean your mac and lose all those old junk plists, apps you no longer use and other odds n sods you can't even remember putting on there.
Then there's the safety aspect. Without physical media, a hard drive failure is a real problem.
Anyway, the work around is pretty simple, using the downloaded 'Install Mac OS X Lion' app you can easily make a bootable DVD that can be used either for a clean install of Lion (sans Snow Leopard) or as an emergency backup.
You will need the following: -
- A Mac with DVD writer
- A copy of the Lion Installer App (available from the AppStore)
- A blank DVD-R (Single layer 4.7GB is fine)
1 - Go to the Applications folder and right click (or Control-Click) on 'Install Mac OS X Lion' and select 'Show package contents'.
2 - Navigate to the Contents > SharedSupport folder
3 - Copy InstallESD.dmg to someplace (eg. your Desktop)
4 - Open Utilities > Disk Utility.app and click 'Burn'. In the window that opens, choose the copy of InstallESD.dmg you just made, then click Burn.
5 - Wait a few mins for the disk to burn and verify and your done.
6 - If you are using a printable DVD or labels, here's a Mac OS X Lion 10.7 DVD Label I made that you might want to use.
