You'll need to have the xz utility installed (download from The Tukaani Project [ ht-
tp://tukaani.org/xz/ ] ). Uncompress the image by using the following command (this will
take a minute or so):
mac$ unxz bone-debian-7.7-lxde-4gb-armhf-2014-11-11-4gb.img.xz
Then write it to the microSD card, substituting your device path noted earlier ( /dev/
rdisk1 , in my case) for the device path given in the dd command:
mac$ sudo dd if=bone-debian-7.7-lxde-4gb-armhf-2014-11-11-4gb.img
of=/dev/rdisk1
You'll need to type in your password. The dd command takes 5 to 10 minutes.
WARNING
This operation will wipe out everything on the microSD card. It might be worth plugging in
your card, noting the path, removing the card, noting it has disappeared, and then plugging it
in again and checking the path. You can really mess up your host if you have selected the
wrong disk and used the wrong path. Be careful.
NOTE
Note that I used rdisk1 rather than disk1 . According to the eLinux wiki , doing so will
speed up writing quite a bit.
