the SD card is /dev/disk2 in my case

• unmount the SD card sudo diskutil unmount /dev/disk2
• write the image to SD card
  sudo dd bs=1m if=2017-04-10-raspbian-jessie.img of=/dev/disk2
• eject the SD card sudo diskutil eject /dev/rdiskX

Connecting to raspberry

Reference

• Create an empty file ssh on root directory of the SD card touch /ssh
• Create a file vi /wpa_supplicant.conf on root directory

country=GB
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
    ssid="<wifi ssid>"
    psk="<wifi password>"
}

• ssh pi@<IP of the raspberry>
• default password is raspberry
