I was able to successfully complete the process, though I had to use the script referenced above on this page:

The signature on a pkg can be quickly identified and stripped without extracting and flattening the package. I put together a quick proof of concept tool to do it: https://github.com/etrepum/strip_pkg_signature

That seems like it would be a lot faster than my method! Please go back in time three weeks and release your tool!

This process worked well, and was very fast indeed! I had to make a new dmg, but I deleted the programs I don’t want anyway to make a smaller dmg. THANK YOU for hosting this page and creating the solutions!!! Install was successful, THANKS TO YOU!!

Thanks for the tip! Fortunately, iWeb is one of the features I DON’T want, so maybe I can redo all the others individually. I believe there are instructions above to do just that (I was trying to do the whole install dmg in one fell swoop), but I’ll re-read this page. Thank you.

Sounds like the disk image of your iLife DVD might be corrupt, since it can’t successfully expand the iWeb.pkg.

You could confirm by trying to do it manually.

Great tool–thank you!!! Unfortunately, I’m unable to get it to work properly. After the python script runs for a few minutes (expanding/flattening the different packages), it ends up giving me an error during what I think is nearly the end of the process:

Excerpt of lines just prior to the failure:

Expanding /private/tmp/dmg.1NOv20/Installer/Packages/iPhotoLibraryUpgradeTool.pkg to /tmp/tmpo8zsi9/iPhotoLibraryUpgradeTool.pkg…
Flattening /tmp/tmpo8zsi9/iPhotoLibraryUpgradeTool.pkg to /tmp/tmpKWA4TZ/iPhotoLibraryUpgradeTool.pkg…
Expanding /private/tmp/dmg.1NOv20/Installer/Packages/iWeb.pkg to /tmp/tmpo8zsi9/iWeb.pkg…
Problem extracting file from package: /tmp/tmpo8zsi9/iWeb.pkg/Payload
ERROR: Command ‘['/usr/sbin/pkgutil', '--expand', '/private/tmp/dmg.1NOv20/Installer/Packages/iWeb.pkg', '/tmp/tmpo8zsi9/iWeb.pkg']‘ returned non-zero exit status 1 expanding /private/tmp/dmg.1NOv20/Installer/Packages/iWeb.pkg

I tried re-running the entire workflow, step-by-step as described on this page (thanks for the wonderful instructions). However, it failed at the exact same place again, with the same error message. I know just enough to be dangerous, so could somebody please kindly enlighten me as to what my problem might be, and how I might go around fixing it? Just in case it helps, here are the exact commands I’m running:

sudo chmod a+x ~/Desktop/flatpkgfixer.py

sudo python ~/Desktop/flatpkgfixer.py ~/Desktop/Apple/iLife\ \’11\ Install\ DVD.dmg ~/Desktop/iLife11_fixed.dmg

[...] I was not able to install the downloaded MAC to the flash drive for the installation. I was getting the "Certificate Expired Error" and by doing google I found a script which fixes this issue. http://managingosx.wordpress.com/201…ed-signatures/ [...]

A similar question was asked and answered earlier in this set of comments. I replied then:

flatpackagefixer.py is a Python script. You’ll either need to set the execute bit:

chmod a+x /path/to/flatpackagefixer.py

Then:

/path/to/flatpackagefixer.py /path/to/iLife.dmg /path/to/iLife11_fixed.dmg

(all one line)

Or call it from python:

python /path/to/flatpackagefixer.py /path/to/iLife.dmg /path/to/iLife11_fixed.dmg

(all one line)

Sorry Greg for the complete noob question. I googled a lot on how to execute .py on mac. How do I execute your script python on ML ?

thank you so much for this – it worked with the newly installed mountain lion – now Iphoto works again. Had I known it would cause so many problems I would not have bothered with it at all. Thanks again.

I think you are missing further information about the code I had to refer to some commentary
