Automated installs of Mac OS X Lion

OS X Lion imageI’ve made some tools for creating an automated install of Mac OS X Lion available for testing and feedback. These tools do not require Munki — you should be able to use them with any software distribution mechanism that can install Apple packages.

git clone

Enjoy! Feedback and discussion should be directed to the munki-dev list at

      Ryan, perhaps you can help me, as I want to deploy it as well through ARD. I did the steps as in the text do, no adjustments, just copied the dmg into the lion pkg with the command that was given. I can copy the installlionpkg to the users desktop, and start it gfrom there, that works great, but the install option from ARD gives me te error: can’t be installed.. Any tips or trucs? the machine i want it to deploy to is a 10.6.8 imac with the right specs..

    Hi, there were several errors, but the solution was a simple one..
    I got the InstallESD.dmg from a collegae, but with the name InstallLionEsd.dmg. Renamed the file back, and it all works like a charm! Edwin

    1. That should be handled by whatever method you are using to deploy this. For example, munki will delete a diskimage containing this package after it’s been successfully installed, but before the reboot.

    Hi, This looks really useful, but I’m stuck on the first step. I’m working from an Apple Lion thumb drive. There doesn’t seem to be a SharedSupport folder in Contents. Any idea where I can find the InstallESD?

  3. Dennis – that makes sense. So it would be difficult to use the thumb drive as a starting point for an InstallLion.pkg. Spend $30 and get the App Store download.

    1. You really should inspect the package and see for yourself what it is doing. For all you know, it’s installing a key logger and mailing the contents of all your private documents to Russia.
