  1. Thanks, but the final comand it must be separate, like:

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

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

    sudo rm -fv /tmp/Monterey.dmg

  2. In my work it is great to have a disk with several install macOS versions. I was creating on a disk then imaging them using Disk Utility’s “New Image from…”. Then I would keep the images for restore on to an external drive(s) as needed. I now get the error, Operation failed with status 1: Operation not permitted”.

    Your method gets me the image, I skipped the make ISO part, but I can’t use Disk Utility’s “Scan Image for Restore”. Is there a way to do this in the terminal?
