Install Ubuntu on Odroid XU4 using Mac

Download

The first thing you have to do is download the img file, you can download the last Ubuntu version for Odroid on the Odroid Wiki .
There are 2 versions one with mate desktop and another minimal installation (the minimal doesn't install a desktop).
You also can download the md5sum to check the integrity of the downloaded file.

Extract the file

The file is compressed as .xz format, you will need another program to extract the file, I used The archive browser but there are more apps that you can use for example the Unarchiver or install xz.

Flashing

To flash ubuntu on the sd card we are going to use Disk Destroyer (dd), is already included on OS X. Be careful it will erase everything on your sd card and the new format will be EXT4 so you will need drivers to read the sd card after flash the card, but that is optional.

Before to start we have to unmount the sd card.
If you don't know where is the sd card you can use this command:

diskutil list

The output is something similar to this:

/dev/disk0 (internal):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                         500.3 GB   disk0
   1:                        EFI EFI                     314.6 MB   disk0s1
   2:          Apple_CoreStorage Macintosh HD            499.3 GB   disk0s2
   3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

/dev/disk1 (internal, virtual):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:                            Macintosh HD           +498.9 GB   disk1
                                 Logical Volume on disk0s2
                                 Unencrypted

/dev/disk2 (external, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:     FDisk_partition_scheme                        *64.0 GB    disk2
   1:             Windows_FAT_16 BOOT                    67.1 MB    disk2s1
   2:                      Linux Untitled                64.0 GB    disk2s2

My sd card is disk2. By default OS X mounts the disk, the command to unmount the drivers is diskutil:

diskutil unmountDisk /dev/disk2

Once the memory is unmounted we can flash the img image in the sd card with this command:

sudo dd if=<my/odroid/image.img> of=</dev/path/of/card> bs=1m

Example:

sudo dd if=/Users/wdiaz/Downloads/ubuntu-16.04-minimal-odroid-xu3-20160706.img of=/dev/disk2 bs=1m

If all is correct the output will be similar to this:

1947+0 records in
1947+0 records out
2041577472 bytes transferred in 180.054660 secs (11338654 bytes/sec)

Now you can unmount the sd card again and use it in you Odroid.
