Install Raspian onto an SD card using a MAC

Open a terminal window and use the following commands:

  diskutil list
  diskutil unmountDisk /dev/disk2
  sudo dd bs=1m if=2013-05-25-wheezy-raspbian.img of=/dev/disk2

Note: replace "disk2" with the id of the SD card. If you are unsure, remove the card and use diskutil list, then insert the card and use the diskutil list command to see the additional device.
