if you are using the Terminal/shell anyway, you may skip steps 3, 4, 5 and 6… in Terminal/shell enter:

mount # check the output for target volume
sudo diskutil unmount /dev/diskx # use device-path as reported by mount
sudo dd if=image.img of=/dev/diskx bs=64k

dd… bs=64k: blocksize 64k speeds up things considerably (on most unixes, that is… experiment with other block-size if you encounter problems)

sudo diskutil unmount /dev/diskx
