1) SD card prep.
Download SD card formatter for OS X: https://www.sdcard.org/downloads/formatter_4/eula_mac/
Run it, using ‘Overwrite’ option. This takes a long time.
Then download a Raspberry Pi OS. I downloaded NOOB. Unzip it. Copy all the files in the unzip dir to the SD card.
2) Insert SD card, plug in HDMI to monitor, cell phone charger to power, mouse to USB port.
On power up, select the debian OS install. After it installs, the Pi reboot. Unplug the mouse and plug in a keyboard. Finish the setup using the menu. After setup, it drops the user to a command line.
3) Setup the WiFi. I want it to connect by DHC
