e.g.
diskutil unmountDisk /dev/disk4
sudo dd bs=1m if=image.img of=/dev/<disk# from diskutil>
e.g.
sudo dd bs=1m if=2015-02-16-raspbian-wheezy.img of=/dev/disk4
This may result in a
dd: invalid number '1m'
error if you have GNU coreutils installed. In that case
you need to use
1M
:
sudo dd bs=1M if=image.img of=/dev/<disk# from diskutil>
This will take a few minutes.
4.5.3. Alternative method
Note: Some users have reported issues with using Mac OS X to create SD cards.
These commands and actions need to be performed from an account that has administrator privileges.
•
From the terminal run
df -h
.
•
Connect the SD card reader with the SD card inside.
•
Run
df -h
again and look for the new device that wasn't listed last time. Record the
device name of the filesystem's partition, for example
/dev/disk3s1
.
•
Unmount the partition so that you will be allowed to overwrite the disk:
sudo diskutil unmount /dev/disk3s1
Or open Disk Utility and unmount the partition of the SD card (do not eject it, or you will have to
reconnect it)
•
Using the device name of the partition, work out the raw device name for the
entire disk by omitting the final "s1" and replacing "disk" with "rdisk". This is very
important as you will lose all data on the hard drive if you provide the wrong
device name. Make sure the device name is the name of the whole SD card as
described above, not just a partition of it (for example, rdisk3, not 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:
