Writing Raspberry Pi image to SD Card from MacOS

[gdt]

Insert the SD card, via a USB dongle is that is needed.

$ diskutil list

Grab the device name, in this blog posting it is /dev/disk1.

Rewrite the partition table to delete the disk. This will also solve any permissions issues on the /dev/disk1 device.

$ sudo diskutil partitionDisk /dev/disk1 1 MBR "Free Space" "%noformat%" "100%"

Write the downloaded image to the SD card. Using unzip -p sends the image file within the .ZIP archive directly to "dd" to be copied to the SD card. That saves some time and disk space.

$ unzip -p Downloads/2014-06-20-wheezy-raspbian.zip 2014-06-20-wheezy-raspbian.img | dd of=/dev/disk1 bs=1m
$ diskutil eject /dev/disk1
