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?

From my tests today, no you are not. It boots flawlessly on anything with a built-in NIC, Retinas are another story. I found the boot will often stall as you describe with a Thunderbolt-Ethernet adapter.

I've had near 100% success with a USB-Ethernet adapter, however. If you have one of those around, give it a whirl to see if you have better luck.

Looks like 10.11.6 may have fixed it this time. We've done a few Thunderbolt-cable'd installs this morning with 0 issues.

Wondering if 10.11.6 fixes this issue: About the OS X El Capitan v10.11.6 Update - Apple Support

"Resolves an issue that may prevent startup from a NetBoot image created with an OS X v10.11.4 or OS X v10.11.5 installer."

Will have some testing to do tomorrow.

Please read this thread:

Netrestore of 10.11.4 and 10.11.5 FAIL

Here OS X 10.11.6 NetInstall seems to work again without any workarounds.
