CREATING ISO IMAGE
There will be 2 effective ways to create a bootable iso file from a install macOS Mojave.app file.

METHOD 1: Use of command lines through Terminal - Recommended to use
Thank Github-thelamehacker for these command lines.

  • Open Terminal (/Applications/Utilities/), then Enter the following command lines in order (administrator password is required during the process).

hdiutil create -o /tmp/Mojave.cdr -size 6g -layout SPUD -fs HFS+J

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

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

mv /tmp/Mojave.cdr.dmg ~/Desktop/InstallSystem.dmg

hdiutil detach /Volumes/Install\ macOS\ Mojave

hdiutil convert ~/Desktop/InstallSystem.dmg -format UDTO -o ~/Desktop/Mojave.iso

mv ~/Desktop/Mojave.iso.cdr ~/Desktop/Mojave.iso

rm ~/Desktop/InstallSystem.dmg

  • After above steps, we get the MacOS Mojave.iso.cdr on the desktop.
  • Just change the name by removing the “.cdr”, you get MacOS Mojave.iso files, which can be used to create bootable USBs, DVDs, install VMs.
