I discovered something from lion 10.7 InstallESD.dmg with md5 'b5d3753c62bfb69866e94dca9336a44a'.

when we open the above dmg in 7-zip, it contains another InstallESD.dmg (in folder InstallMacOSX.pkg) that has a different md5, 4c2bda281dd39b562e478dc94895b9be. I experimented both Retail and GM versions of InstallESD.dmg and found they both have inside another dmg file with a different hash, 4c2bda281dd39b562e478dc94895b9be

Found another interesting thing,

InstallESD.dmg
with md5, b5d3753c62bfb69866e94dca9336a44a cannot be converted to ISO showing 'inflation failed' in dmg2img.


But the InstallESD.dmg with md5, 4c2bda281dd39b562e478dc94895b9be inside the above b5..InstallESD.dmg can be converted to ISO.

Will show again the parent dmg and child dmg,

Parent- InstallESD.dmg (b5d3753c62bfb69866e94dca9336a44a)

Child- InstallESD.dmg (4c2bda281dd39b562e478dc94895b9be)


Found no difference between both dmg's except md5 and the child can be converted to ISO.

Do anyone know why is there another dmg inside the original b5..dmg released by apple?.

Thanks for sharing this important information, as it does work and I have used it to create an ISO and VMDK to install Lion.

This has to be sticky...amazing info...

So with the new iso from the dmg file....can one boot it up in vmware and install it directly..like in the way of SL install?
