  • Under mac this runs much faster if you use “sudo dd bs=1M if=your/file/here.img of=/dev/rdisk4” rather than “sudo dd bs=1M if=your/file/here.img of=/dev/disk4” . That is “rdisk” rather than “disk”. See http://superuser.com/questions/631592/why-is-dev-rdisk-about-20-times-faster-than-dev-disk-in-mac-os-x
