Locate your sd card

$ diskutil list
/dev/disk0
#:                       TYPE NAME                    SIZE       IDENTIFIER
0:      GUID_partition_scheme                        *500.3 GB   disk0
1:                        EFI EFI                     209.7 MB   disk0s1
2:                  Apple_HFS Macintosh HD            399.5 GB   disk0s2
3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3
4:       Microsoft Basic Data BOOTCAMP                99.8 GB    disk0s4
/dev/disk1
#:                       TYPE NAME                    SIZE       IDENTIFIER
0:     FDisk_partition_scheme                        *31.9 GB    disk1
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)

how do I use the sd size for the whole system ?

$ diskutil list

but error occur, I need help.

Unmount of disk3 failed: at least one volume could not be unmounted

unxz -c ubuntu-15.04-snappy-armhf-rpi2.img.xz | sudo dd of=/dev/rdisk3 bs=32m && sync && say done

but error occur, I need help.

dd: /dev/rdisk3: Resource busy

worked great. Thanks for sharing.

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.
