                   default path.
      -i, --iso
                   Path with optional name for output .iso
      -m, --method
                   Use method number D to create installation image:
                   Method 1 create image that most close to Apple's image,
                   but potentially less compatible with some BIOSes/EFI.
                   Method 2 create more BIOS/EFI-friendly images, but
                   require more disk space for conversion.
                   Method 3 can produce bootable images without super
                   user rights.
      -n, --nosudo
                   Do not use sudo command
      -v, --verify
                   Do not skip verifications (slow down image creation)
      -h, --help   Print this message and exit
