InstallESD.dmg [MD5], Some Info Discovered!

5 posts in this topic

Recommended Posts

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?

    • You can try this one here 2.9.0 let me know if its better for you ?   VoodooHDA.kext.zip
    •   Boot option name retrieval 1) Locate the booter image as explained blow. 2) Locate ".contentDetails" in the parent folder 2.1) if unsuccessful, locate ".disk_label.contentDetails" in the parent folder 2.2) if unsuccessful, retrieve the volume's name   HFS Boot 1) Retrieve blessed file via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleBless.h#L41 1.1) if unsuccessful, retrieve blessed folder via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleBless.h#L45, append "\\boot.efi". NOTE: This is broken in the latest binary I checked. 1.2) if unsuccessful, use the following hard-coded paths: "\System\Library\CoreServices\boot.efi", "\EFI\APPLE\{ARCH}\BOOT.EFI", <StandardEfiPath>, "\\boot.efi" in this order 2) FV2 Recovery does not follow the usual practice because it is not shown by BootPicker anyway. Determine it via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleBless.h#L49, verify it does not match 1).   APFS Boot 1) Determine the APFS Volume Info (and hencefor detect whether it is APFS in the first place) via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleApfsInfo.h#L54 1.1) Determine the APFS Container Info via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleApfsInfo.h#L36 1.2) Verify the Volume Role via https://github.com/CupertinoNet/EfiPkg/blob/development/Include/Guid/AppleApfsInfo.h#L51 1.3) Retrieve blessed file analoguous to HFS 1). NOTE: This step and 1.3.1) are broken in the binary I checked, hencefor it does not happen, but is probably supposed to. 1.3.1) if unsuccessful, retrieve blessed folder and append the booter name the same way as in HFS 1.2) 1.4) (if unsuccessful,) locate all Volumes that are part of the same container, check whether the current Preboot partition has folders named by the just located Volumes' GUIDs and append the hard-coded paths from HFS 1.2) if existant 2) Recovery detection works the same way as 1.4), just for a Recovery instead of a Preboot volume

    • For F6 Bios, which DSDT is the one i should use? I´m a little confused in the Mass of DSDT here ;-).   Great Thread by the Way.   Another Question: I have 2 960Pro inside my Rig (one with OS X, one with Windows 10). When i try to mount my EFI on OS X NVMe the system freezes... :-(   DWhen i unplug the Windows NVMe everything is fine an it mounts the EFI.   Anybody an idea?   Tried the upper Port on the Board (OS X) & the middle / lower Port, in the Middle it mounts the EFI in the lower it freezes.   But i need the middle Port for an SATA M.2 SSD :-D... Even when i plug the Windows NVMe into an PCIe Adapter Card it freezes at the point i mount the EFI.   I´m mounting with Clover Configurator.     Thank You guys.
    •   Just add "ngfxsubmit=0" to config.plist to disable the fix within nvidiafixup
