rdisk3s1). Similarly, you might have another SD drive name/number like
rdisk2 or rdisk4; you can check again by using the
df -h
command both before
and after you insert your SD card reader into your Mac. For example,
/dev/disk3s1
becomes
/dev/rdisk3
.

In the terminal, write the image to the card with this command, using the raw
disk device name from above. Read the above step carefully to be sure you
use the correct rdisk number here:
sudo dd bs=1m if=2015-02-16-raspbian-wheezy.img of=/dev/rdisk3
If the above command reports an error (
dd: bs: illegal numeric value
), please
change
bs=1m
to
bs=1M
.
If the above command reports an error
dd: /dev/rdisk3: Permission denied
then
that is because the partition table of the SD card is being protected against
being overwritten by MacOS. Erase the SD card's partition table using this
command:
sudo diskutil partitionDisk /dev/disk3 1 MBR "Free Space" "%noformat%" 100%
That command will also set the permissions on the device to allow writing.
Now try the
dd
command again.
Note that
dd
will not feedback any information until there is an error or it is
finished; information will be shown and the disk will re-mount when
complete. However if you wish to view the progress you can use 'ctrl-T'; this
generates SIGINFO, the status argument of your tty, and will display
information on the process.

After the
dd
command finishes, eject the card:
sudo diskutil eject /dev/rdisk3
(Or: open Disk Utility and eject the SD card)
