10.11.4 not loading from NetInstall
Since 10.11.4 came out yesterday, I'm starting to test it with our OS X Server's NetInstall. I've downloaded it three times, and run SIU on it using both our existing 10.11 workflow as well as creating a new one. The workflow runs through fine, and 10.11.4 shows up on the server. However, when I try to boot to install it, the Mac (tried mostly Retina MBPs) starts booting the installer, gets about 3/4 of the line, then just stops.
It was happening yesterday when I was on 10.11.3 with Server 5.0.15, and it's still happening now that I've upgraded the server to 10.11.4 with Server 5.1.
Am I unique with this situation?
