macOS Mojaveのインストール用ISOイメージを作成する方法

macOS MojaveをDVDのイメージを使用してインストールする必要が出たので、インストール用DVDの作するためのメモ

「macOS High Sierraのインストール用ISOイメージを作成する方法」が参考にしていた、highsierra_bootable.shを参考にMojaveのイメージを作成する。

参考

手順

2層DVD-Rに焼くためにサイズを7316m→6500m、8965m→7800mに変更しているが、DVD-Rなので、Disk fullにならなければOKとしている。

# Mojave
# Generate a BaseSystem.dmg with 10.14 Install Packages
hdiutil attach '/Applications/Install macOS Mojave.app/Contents/SharedSupport/InstallESD.dmg' -noverify -mountpoint /Volumes/mojave
###hdiutil create -o /tmp/MojaveBase.cdr -size 7316m -layout SPUD -fs HFS+J
hdiutil create -o /tmp/MojaveBase.cdr -size 6500m -layout SPUD -fs HFS+J
hdiutil attach /tmp/MojaveBase.cdr.dmg -noverify -mountpoint /Volumes/install_build
asr restore -source '/Applications/Install macOS Mojave.app/Contents/SharedSupport/BaseSystem.dmg' -target /Volumes/install_build -noprompt -noverify -erase
rm /Volumes/macOS\ Base\ System/System/Installation/Packages
cp -R /Volumes/mojave/Packages '/Volumes/macOS Base System/System/Installation/.'
df -m '/Volumes/macOS Base System'
hdiutil detach '/Volumes/macOS Base System/'
hdiutil detach /Volumes/mojave/
mv /tmp/MojaveBase.cdr.dmg /tmp/BaseSystem.dmg


# Restore the 10.14 Installer's BaseSystem.dmg into file system and place custom BaseSystem.dmg into the root
###hdiutil create -o /tmp/Mojave.cdr -size 8965m -layout SPUD -fs HFS+J
hdiutil create -o /tmp/Mojave.cdr -size 7800m -layout SPUD -fs HFS+J
hdiutil attach /tmp/Mojave.cdr.dmg -noverify -mountpoint /Volumes/install_build
asr restore -source '/Applications/Install macOS Mojave.app/Contents/SharedSupport/BaseSystem.dmg' -target /Volumes/install_build -noprompt -noverify -erase
cp /tmp/BaseSystem.dmg '/Volumes/macOS Base System/.'
df -m '/Volumes/macOS Base System/.'


hdiutil detach '/Volumes/macOS Base System/'
hdiutil convert /tmp/Mojave.cdr.dmg -format UDTO -o /tmp/Mojave.iso
mv /tmp/Mojave.iso.cdr $PWD/Mojave.iso
rm /tmp/Mojave.cdr.dmg

出来上がった Mojave.iso を使用してVMWareで起動したから、おそらく2層DVD-Rでも行けるかも。。。。
