How to make a macOS Sierra DVD Installer

First, let me give credit where it's due.  This guide was written by Mac Rumors user TyWebb13.

Here is the original post.

To do this copy and paste these into terminal to make the bootable iso file (assuming you have already downloaded Sierra to your Applications folder via the mac app store):

hdiutil attach /Applications/Install\ macOS\ Sierra.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

hdiutil create -o /tmp/Sierra.cdr -size 7500m -layout SPUD -fs HFS+J

hdiutil attach /tmp/Sierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build

asr restore -source /Volumes/install_app/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase

rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages

cp -rp /Volumes/install_app/Packages /Volumes/OS\ X\ Base\ System/System/Installation/

cp -rp /Volumes/install_app/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System/BaseSystem.chunklist

cp -rp /Volumes/install_app/BaseSystem.dmg /Volumes/OS\ X\ Base\ System/BaseSystem.dmg

hdiutil detach /Volumes/install_app

hdiutil detach /Volumes/OS\ X\ Base\ System/

hdiutil convert /tmp/Sierra.cdr.dmg -format UDTO -o /tmp/Sierra.iso

mv /tmp/Sierra.iso.cdr ~/Desktop/Sierra.iso

A bootable iso file called Sierra.iso will then appear on your desktop and you can use this to burn it to a dual layer dvd:

sudo drutil burn /Users/YOURNAME/Desktop/Sierra.iso

where you replace "YOURNAME" with the username for the account you are logged into at the time.

and then boot to startup manager with option key to select the dvd.
