Q: 10.11.4 not loading from NetInstall

Works fine here on a home LAN. I restarted my rMBP and selected the 10.11.5 NetInstall. The rMBP booted to the OS X Utilities Menu. I launched DU - QUIT; then launched Reinstall OS X. I QUIT the installer since I really didn't want to install it.

Is your situation different? Are you able to boot to the OS X Utilities Menu, but not able to actually install when Reinstall OS X is selected?

Mac Mini late-2014

OS X Server 5.1.15

NetInstalls - OS X El Capitan 10.11.5, OS X Yosemite 10.10.5, OS X Mavericks 10.9.5, OS X Mountain Lion 10.8.5

Make Available over: NFS

MBP Retina early 2015

Thunderbolt-Ethernet Adapter

OS X 10.11.5

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.
