Heads up to TUAW for finding this from EggFreckles. If you’re in this situation, it might be best to download Lion from a public wifi hotspot and then create a boot disk manually using the above method so that you can install it on your other Macs. Some of the complaints regarding Lion being distributed through the App Store are from users who have ISP’s with bandwidth caps, a particularly common scenario for anyone using a cellular connection. The final release of Mac OS X Lion is said to be a 4GB download. Now launch Disk Utility (/Applications/Utilities/), pop in a blank DVD, select the “InstallESD.DMG” file, and click on “Burn”Īfter your disk is done burning, you’ll be able to boot from it with any Lion compatible Mac by holding down C during boot up.Copy “InstallESD.dmg” to your Mac OS X Desktop, this is the Lion disk image and what you’re going to create the bootable DVD from.Find and open the “SharedSupport” folder and locate a disc image file called “InstallESD.dmg”.

From the Mac OS X Finder, locate the Mac OS X Installation file that was downloaded, right-click, and “Show Package Contents”.Download Mac OS X Lion from the Mac App Store ($29.99).These instructions are born from the 10.7 developer preview but should remain identical come time for the July public release: Creating a Bootable Install Disc for Mac OS X Lion
