    Create Disk Image
Note
The size of the disk image (16410m) should be adequate for the macOS installer; this value may vary depending on the actual size needed.
  1. Mount the disk image you created using the following command:

    hdiutil attach /tmp/Sequoia.dmg -noverify -mountpoint /Volumes/Sequoia

    Mount Disk Image

    sudo /Applications/Install\ macOS\ Sequoia.app/Contents/Resources/createinstallmedia --volume /Volumes/Sequoia --nointeraction

    Create Installation Media
Note
Ensure that the name of the macOS installer app (e.g., “Install macOS Sequoia.app”) is correct and matches what you have in your Applications folder.
  1. Eject the disk image once you see the message "Install media now available at "/Volumes/Install macOS Sequoia".

    hdiutil eject -force "/Volumes/Install macOS Sequoia"

  2. Continue to run the command to convert the disk image to a CRD file.

    hdiutil convert /tmp/Sequoia.dmg -format UDTO -o ~/Desktop/Sequoia

  3. Execute the command below to rename the CDR file to an ISO file.

    mv -v ~/Desktop/Sequoia.cdr ~/Desktop/Sequoia.iso

  4. Delete the temporary disk image file with the following command:

    rm -fv /tmp/Sequoia.dmg
