HOW TO NETBOOT A MAC YOSEMITE INSTALL
Open the Terminal from the Utilities menu and use the command-line installer to install the bootstrapping packages onto the main partition. Connect a USB drive (a flash stick will do) containing the bootstrapping packages. Second one: Boot the new Mac into the Recovery partition. I found two.įirst one: after starting the new Mac in Target Disk Mode, connect to another Mac running OS X Yosemite 10.10.2, and install the bootstrapping packages. I did not have the time (or desire) to get to the bottom of this issue I needed to find a successful procedure for getting these new 2015 Macs to build. My theory was that there is a bug causing the Installer on Mavericks to do something “wrong” when installing to a Yosemite CoreStorage volume that led to file system corruption.
We were connecting these machines (in Target Disk Mode) to a Mac running Mavericks (10.9.5). The new machines all ship with an unencrypted CoreStorage volume as their main system volume, and. We saw this behavior on multiple new 2015 machines. A check with Disk Utility claimed the startup volume had unrepairable filesystem corruption, and advised us to back up any user data, format, and re-install. After using Target Disk Mode to install the packages, upon reboot the Macs were refusing to boot, or booting very slowly. This approach has worked well for us in the past with new hardware, and allowed us to deploy new hardware to users much faster than if we had to build hardware-specific NetBoot and AutoDMG images.īut these new 2015 Macs were throwing us a curve ball. Munki takes over and installs everything else we need. 
Once these packages are installed on the new machine, we shut it down, connect it to the network, and start it up.
A package to put Munki in “bootstrap mode” on first boot. A package to disable the Setup Assistant. A package to create a local admin account. While there are ways of capturing the hardware-specific OS so you can use it with AutoDMG and to create NetBoot sets, usually what we do with new hardware like this is employ a “no-imaging” process: we boot the new machine in Target Disk Mode, attach it to another Mac, and install some “bootstrapping” packages on the new Mac. These models have new builds of 10.10.2, and won’t boot from our current NetBoot/DeployStudio Server. We’ve recently gotten a few of the new 2015 Macs, specifically the new MacBook Airs and 13″ MacBook Pros. HOW TO NETBOOT A MAC YOSEMITE CODE
More importantly, you can test new versions (or work on the code yourself and test new versions you build) without having to build a new NBI each time. But if you just want to take a look and play with the tool, and you have an existing DeployStudio NBI with Python support included, you can play with Imagr without needing to build a new NBI.

Graham has posted detailed instructions on how to build a NetBoot image that contains Imagr. If Imagr can meet your imaging/machine build needs, you can finally get rid of that poor Mac mini sitting on a shelf in the server room.
Almost every service of interest to OS X admins can be run on platforms other than OS X with the huge exception of a DeployStudio server. This means that you (potentially) can eliminate the last OS X device in your server room/data center.
And most importantly: it does not require a specialized server: it can work with any plain-old web server. It’s written in Cocoa-Python, with much of the “interesting” tasks in Python - a language many OS X admins are familiar with. You can fix bugs and perhaps even help add features to the product. 
Open source means you can look at the code and see what it is doing.
It is open source! DeployStudio is free, but the source is closed. Though Graham claims it is not intended to be a replacement for DeployStudio, I think in time it could very well be exactly that, at least for many people/organizations. It is able to restore a disk image and install packages on a target volume. Imagr is an application designed to be run from a NetInstall environment.
