Day 1 • Lesson 1 — Meet Your Mac: What to Plug In, What the Ports Mean, and How to Turn It On

Lesson Description

In this lesson, you’ll get a calm, beginner-friendly tour of the outside of your iMac — plus a quick orientation to MacBook Pro ports. You’ll learn exactly what to plug in, what the most common ports mean, and how to safely power on and log in for the first time without second-guessing yourself.


This lesson is designed to remove fear and confusion before we ever go “inside” macOS.

What You’ll Learn

By the end of this lesson, you’ll be able to:

  • Plug in and power on your iMac correctly
  • Understand what USB-C ports are — and why some have a Thunderbolt symbol
  • Tell the difference between USB-C, USB-A, and Lightning cables
  • Know when (and why) a small adapter is needed
  • Charge your keyboard and mouse properly
  • Power on your Mac and confidently complete the first login
  • Recognize the most common MacBook Pro ports (USB-C, HDMI, SD card, headphones, power)

While you watch, look for:

Where the power button is (back-left area) + what you see/hear on startup (chime + Apple logo).

Charging basics: keyboard uses USB-C; some mice use Lightning; the mouse can’t be used while charging.

First login screen: you’ll hit Return/Enter after typing your password.

Quick Recap

  • Apple cables are designed to fit only where they belong
  • Thunderbolt ports are just “faster USB-C” ports
  • Older devices may need a USB-A → USB-C adapter
  • It’s safe to leave your keyboard and mouse turned on
  • Nothing bad happens if you unplug and re-plug something

Do This Now (2–10 minutes)

Complete this mini-action while it’s fresh:

Plug in power (magnetic connector) + plug into surge protector.

Power on and reach the password screen.

Log in successfully.

Done looks like: You’ve booted and landed on the desktop at least once.
