Convert Mac OS X DVD image to ISO
It is possible to convert a Mac OS X disk image to a DVD or CD-ROM master by opening it in disk image, and selecting Convert from the Images menu. However, this will not work as a disk image in VMware.
To convert a CD/DVD master (extension .cdr) to an ISO with Windows-compatible Joliet file system, issue the following command in the terminal:
hdiutil makehybrid -iso -joliet -o [output file] [input file]
