In this instructable, I'm going to demonstrate to you how to setup your Mac to allow any other Macs on your network to boot from it. Apple actually put all the pieces into the operating system to do this! All you really need to do is set it up. Once this is done, it's automatically turned on and managed by the Operating System...
This can be convenient for installing updates, new OS's or performing diagnostics/repairs. My process of accomplishing this will, as often as possible, use the GUI utilities available. Much of it can also be done using command-line instructions, but in my opinion, leaves too much room for errors.
I'm definitely not the first to accomplish this and without the information from others that have, it would have taken me forever to figure out. Nor am I attempting to steal the glory from others that have published processes to do this. While most of this information is available elsewhere, I am attempting to put it all in one place and make it possible for less experienced users to accomplish. Direct references to all of my sources will be in the last step of this Instructable
Also, be sure that you have a license to support any OS or software that you serve to cover all the computers on your network.
