Steps to install:
iTerm is the terminal you are missing out on, for your programming life. Choose the version you want to install from this, downloads page.
Unzip the downloaded file
Move the unzipped iTerm application to the “Applications” folder and now from your Applications folder, double click the iTerm application to run it.
Note: You may have to provide Full Disk Access (which is a privacy option, a choice to make as per your liking) from your privacy section or when your iTerm application hints you to do so.
