d/l latest raspbian from http://www.raspberrypi.org/downloads

connect sd card reader, then at the command line:

 $ diskutil list
    # identify the disk (not partition) of your SD card. e.g. disk2 (not disk2s1)
 $ diskutil unmountDisk /dev/<disk# from diskutil>
 $ sudo dd bs=1m if=<your image file>.img of=/dev/rdisk<disk # from diskutil>
    # for additional speed, we are prepending "disk" with "r" (for raw)
    # e.g. sudo dd bs=1m if=~/Downloads/013-05-25-wheezy-raspbian.img of=/dev/rdisk2
    # (This will take about 2 minutes)

 $ cd /Volumes/boot     # or whatever the volume is called
 
 # OS X puts these here, but they screw up the RPi boot process

 $ rm -rf ._.Trashes
 $ rm -rf .Trashes
 $ rm -rf .fseventsd

 # now set up so we can share internet

 Open Network Preferences -> Ethernet
   Configure IPv4: Manually
   IP Address: 192.168.2.1
   Subnet mask: 255.255.255.0

 System Preferences -> Sharing
   make sure Internet Sharing is *OFF* (it screws up ssh)

 $ cd /Volumes/boot
 $ subl cmdline.txt: 
   # add 192.168.2.2 to the end of the single line in this file.
 $ diskutil unmountDisk /dev/disk<#> 

 attach the RPi to the ethernet cable and the ethernet cable to the computer, insert SD card, and boot up. Wait a couple minutes, then:

 $ ssh pi@192.168.2.2 
   password: "raspberry"

 Now, on the pi:

 pi$ nano /boot/cmdline.txt
   # REMOVE the 192.168.2.2 from the file (we're going to use /etc/network/interfaces instead)

 pi$ nano /etc/network/interfaces

 remove all lines about eth0 and add the following stanza:

  auto eth0
  iface eth0 inet static
  address 192.168.2.2
	netmask 255.255.255.0
	gateway 192.168.2.1

  Shut down the Pi:

  pi$ sudo shutdown -h 0

  Finally, turn sharing back on:

  System Preferences -> Sharing
    select share your connection from "WiFi"
           to computers using: "Ethernet"

    *now*, check "Internet Sharing" and click "start" when prompted


  Finally, powercycle the Pi, and connect to it:

  $ ssh pi@192.168.2.2
    # may seem to hang for a minute or two while the pi boots up

  and check the internet connection:

  pi$ ping www.google.com
  PING www.google.com (173.194.43.51) 56(84) bytes of data.
