Hey everyone. I have been trying to make an install disc for the other Mac's in my home but every disc I burn - it gets spat out by the machine after burning. Here are the steps I followed. This this no longer valid for the final release? 1. Purchase and download Lion from the Mac App Store on any Lion compatible Mac running Snow Leopard. 2. Right click on Mac OS X Lion installer and choose the option to Show Package Contents. 3. Inside the Contents folder that appears you will find a SharedSupport folder and inside the SharedSupport folder you will find the InstallESD.dmg. This is the Lion boot disc image we have all been waiting for. 4. Copy InstallESD.dmg to another folder like the Desktop. 5. Launch Disk Utility and click the burn button. 6. Select the copied InstallESD.dmg as the image to burn, insert a standard sized 4.7 GB DVD, and wait for your new Lion Boot Disc to come out toasty hot.
