Networking:
- You can use an ethernet cable for a wired connection
- You can set up Wi-Fi with a USB wireless adapter. We've had good luck with the Wi-Pi.
- You can connect your Pi to your mac with an ethernet cable and share your Mac's internet connection. Give the Pi a fixed IP address and use Terminal on the Mac to ssh into the Pi. This eliminates the need for an external monitor, keyboard and mouse.
