Os X Sierra Dmg To Iso

You can use hdiutil to convert from.dmg to.iso directly: $ hdiutil makehybrid -iso -joliet -o filename.iso filename.dmg Renaming.cdr to.iso is bad advice! An.iso has a slightly different format that allows PC users to play the DVD as well. A renamed file will work on macOS, but NOT on a PC.
