Equivalents for genisoimage and qemu-img on Ubuntu How do I achieve the same result on OS X 10.9 as I do on Ubuntu with commands:

$ genisoimage -output init.iso -volid cidata -joliet -rock user-data meta-data


and

$ qemu-img convert -O raw disk.img disk.img.raw
You can use mkisofs instead of genisoimage - they are almost identical (mkisofs is actually newer and better maintained, while genisoimage is debian's old fork of it).

It comes with cdrtools, which you can install from brew:

brew install cdrtools
