Do you have more than one Mac at home? Do you want to update all your Snow Leopards to Lions
Unfortunately, after you upgrade to Lion, the installer is deleted automatically and you have to re-download 4GB of data over the Internet again. Here in Angola with the low bandwidth speeds this is a huge pain in the a**.
But in less than 24hrs a guy figured out how to retrieve the Lion Installer App using Time Machine to create a bootable DVD.
Here is how:
Enter time machine and go to your .../Applications folder. Go back to a place in time & space between the time you finished downloading Lion from the Apple App Store and before you upgraded to Lion. There you will find a 3.6GB application called “Install Mac OS X Lion.app”. Select it and click on restore.
This will copy the file to the current point in time, a.k.a. today, inside the …/Applications folder.
Now follow these steps to burn the image:
- right-click the Lion file and select “Show Package Contents” from the drop-down menu;
- drill down, find and open the “SharedSupport” folder and locate a disc image file called “InstallESD.dmg”;
- copy “InstallESD.dmg” to your Desktop. This is the Lion disk image and from it you’re going to create the bootable DVD;
- launch Disk Utility, pop in a blank DVD, select the “InstallESD.DMG” file, and click on “Burn”. Once completed, your bootable DVD should launch as a new volume on your desktop.
That’s it! You should now have a bootable install disk of OS X Lion to use on all of your authorized Macs! This is not illegal as Apple by default lets you buy Lion once for $29 and then download and install it on all your Macs.
Do make sure all the machines are trully yours!
