Hello ebkseq,
I was in a similar situation where I only had the "InstallESD.dmg" for 10.8.1 and MacPostFactor wouldn't recognize it when mounted, or when I copied the "Install Mac OS X Mountain Lion.app" to the Applications folder. After a bit of searching I was able to find out what the structure of the ML installer from the app store looked like and recreate it.
1. Mount "InstallESD.dmg"
2. Copy the "Install Mac OS X Mountain Lion.app" from the mounted image or your USB to the Applications folder
3. Command click on "Install Mac OS X Mountain Lion.app" in your Applications folder and select "Show Package Contents"
4. Open the "Contents" folder and create a new folder named "SharedSupport"
5. Now copy the "InstallESD.dmg" file and Mac OS X Install ESD/Packages/OSInstall.mpkg the in to "SharedSupport" folder you created in step 4. If you only have the USB you will have to use DiskUtility to make a .dmg
6. Unmount the "Mac OS X Install ESD" disk image (just to be safe)
7. Run MacPostFactor and it should now recognize that what you have created in your Applications folder is the same as the ML installer from the AppStore.
Hope that this helps.
Cheers,
Shaun
Shaun,
I just tried this, following your exact steps, and it did not work. MCPF still does not recognize the installer. In my case, I have a bootable thumb drive for Mac OS X 10.8.5. The "Install Mac OS X Mountain Lion" application is just called "Install" on it. I tried renaming it to "Install Mac OS X Mountain Lion" and MCPF would not recognize it, nor would MCPF recognize it when it was only called "Install."
I can't imagine it would be very hard to build the capability into the installer to allow it to work with bootable Mac OS X Mountain Lion Installer thumb drives. Is this on the developers' agenda?
[doublepost=1465174369][/doublepost]I just realized that your step #5 doesn't make any sense. It looks like it is missing some words, or has one or more typos. This is what it says:
"5. Now copy the "InstallESD.dmg" file and Mac OS X Install ESD/Packages/OSInstall.mpkg
the in to "SharedSupport" folder you created in step 4. If you only have the USB you will have to use DiskUtility to make a .dmg"
Are there words missing above? I've bolded the language that doesn't make sense. Are "InstallESD.dmg" and "OSInstall.mpkg" the only files I need to copy into "SharedSupport"?
My guess is the above language is just a typo but perhaps it isn't, and instead some additional file names are missing. I am just struggling to figure out how/why your instructions aren't working.
[doublepost=1465177250][/doublepost]OK, got it to work--so far, at least--crossing my fingers--by renaming the installer to "Install OS X Mountain Lion" instead of "Install Mac OS X Mountain Lion" as was indicated in the earlier instructions.
