Use Your Raspberry Pi As A Headless System Without A Monitor

I have a few Raspberry Pi computers all doing different things around my home. With the exception of my RetroPie, which I’ll talk about in a different article, they were all configured and running as a headless system. So what exactly is a headless system?

Headless Systems via IoT Agenda:

A headless system is a computer that operates without a monitor, graphical user interface (GUI) or peripheral devices, such as keyboard and mouse.

I use an iMac and my TV has all HDMI ports in use making it a hassle to switch them around. This means I needed to configure and use my Raspberry Pi in a different manner.
