Locate your sd card

$ diskutil list
/dev/disk0

1:             Windows_FAT_32 NO NAME                 31.9 GB    disk1s1                       <<< this is the sd card

IN MY CASE IT WAS DISK1 - DO NOT JUST COPY AND PASTE THE BELOW - USE YOUR SD CARD'S DEVICE

Unmount the disk

diskutil unmountDisk /dev/disk1

Prepend r to your disk identifier and execute the following command (in my case i changed disk1 to rdisk1)

$ unxz -c ubuntu-15.04-snappy-armhf-rpi2.img.xz | sudo dd of=/dev/rdisk1 bs=32m && sync && say done

(os x needs a lower case m in 32m, otherwise its 32M)

worked like a charm. If your card size is different than 32, as in my case was 64, use different bs=32m to bs=64 or else it hangs.
