So, in this video, I'll show you how to install and configure iTerm on a Mac. However, iTerm has some additional functionality not present in the default terminal application.
If you want, you can use the built in Terminal application to perform all of the functions I'll describe in this series. Macs comes with one simply named 'Terminal', however, I've chosen to use a popular alternative terminal emulator named 'iTerm'. Most operating systems come with a built-in terminal application.
