I was so excited to get a new mac at work, and even more-so when I realized that Apple's Time Machine successfully imported all of my old files and applications (including the ever-so-rare subscription-free version of Illustrator and Photoshop). There is, of course, no story without a struggle. I found out that I couldn't use git!
Luckily, this guy provided excellent instructions on how to fix the problem. My only addition is a note for anyone who has never accessed the terminal from recovery mode: after you reboot and hold [command + R], you have to select your language, and then click on "utilities" from the upper LEFT portion of your screen. Terminal is listed there.
