In my example, I had to add in the MacBook Air updates because we were deploying 6,000 of them and I wanted them in there. You can manually edit the catalog file to install specific updates you want. This will create an up-to-date OS X OS image file, which is pristine and never been booted. Now, InstaDMG can also amalgamate OS X updates into your image file and output it to the output folder. I know, I know, lead by example, but I wanted to bust this out quickly. I strongly suggest you use sudo instead of a root session for best practices. I am comfortable enough with my skills in the command line to do this for brief projects like using InstaDMG. Note I am running my terminal session as root, via sudo -s. It will complete and put the output files in the InstaDMG folder. I do not think it works on restore DVDs, so you will need a retail OS Disk.

You just open up the terminal and navigate to the python script and execute it with your installer DVD in the optical drive, the rest is taken care for you. So, I downloaded the zip file and extracted it to my home folder, and it is basically just a collection of Python scripts. First you will need to download InstaDMG from it's project page, found here: Though from what I read, Lion does in fact work.Ĭan be used to update your OS image file very easilyĬan be ran and forgot about until it completes This demo will be for OS X 10.6.x because I don't have any Lion production machines yet so I do not fully support it. So, here is an unsorted list on some of the benefits of using InstaDMG with Casper.

That being said I want to make clear you do not need to use InstaDMG, Casper can function with out it. Overall, in my personal and professional opinion it is a very nice and powerful tool that can compliment the JAMF Software Suite. I have heard the debate from all sides of InstaDMG.

So, there has been a lot of on and off discussion about InstaDMG over the years.
