How to Use Mac Terminal, and How to Use Key Functions

We will be showing you how to open the MAC Terminal. We will also be showing you a few features within the Terminal, such as ifconfig, changing directories, accessing files, and arp. Ifconfig will allow you to check your IP address, and your MAC address. This is useful for setting up a new device on a network. Changing directories inside the Terminal can be useful as a more effective way to find document, and folders inside of your computer instead of searching through all of your folders.
