Install Raspbian from OS X
2012.09.19
Download image from raspberrypi.org
Plug in SD card
Identify SD card
df -h
Note: /dev/disk1s1 is the disk on my MacBook Pro. You need to review and change the disk info as necessary.
Unmount
sudo diskutil unmount /dev/disk1s1
Apply image to SD card
sudo dd bs=1m if=2012-09-18-wheezy-raspbian.img of=/dev/rdisk1
These instructions are DANGEROUS! By default, my OSX installation is on /dev/disk1s1, and running this command would be catastrophic – I can’t be the only one, so I suggest you make it explicitly clear that ‘/dev/disk1s1′ and ‘/dev/rdisk1′ should be changed to whatever the SD card is mounted as.
Brilliant. Dangerous, true, but very simple – and it works.
Thanks.
