Building OSX Images for fun and profit

I'm compiling all the build instruction into one repository. It's a bitch to go look for all this on the internets, so I'm just dropping it here for my own convenience.

Mojave OSX 

hdiutil create -o mojave.cdr -size 7316m -layout SPUD -fs HFS+J

hdiutil attach mojave.cdr.dmg -noverify -mountpoint /Volumes/install_build

sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build

mv mojave.cdr.dmg InstallSystem.dmg

hdiutil detach /Volumes/Install\ macOS\ Mojave/

hdiutil convert InstallSystem.dmg -format UDTO -o Mojave.iso 

High Sierra OSX 

hdiutil create -o highsierra.cdr - size 7316m -layout SPUD -fs HFS+J

hdiutil attach highsierra.cdr.dmg -noverify -mountpoint /Volumes/install_build

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia —volume /Volumes/install_build --nointeraction

mv highsierra.cdr.dmg highsierra.dmg

hdiutil detach /Volumes/Install\ macOS\ High\ Sierra/

hdiutil convert highsierra.dmg -format UDTO -o highsierra.iso 

Sierra OSX 

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

hdiutil create -o /tmp/Sierra.cdr -size 7316m -layout SPUD -fs HFS+J

hdiutil attach 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

hdiutil convert sierra.cdr.dmg -format UDTO -o sierra.iso

mv sierra.iso.cdr sierra.iso

El Capitan OSX 

hdiutil attach "/Applications/Install OS X El Capitan.app/Contents/SharedSupport/InstallESD.dmg" -noverify -nobrowse -mountpoint /Volumes/esd

hdiutil create -o elcapitan.cdr -size 7316m -layout SPUD -fs HFS+J

hdiutil attach elcapitan.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/iso
