You have a new iMac in front of you — perhaps a present, a replacement, or a carefully chosen treat after months of thinking about it. This chapter is your gentle first step. It does three simple things: it explains what an iMac is in plain language, it sets a short goal for what you will be able to do after the first hour with your machine, and it gives you clear next steps so you can be confident rather than overwhelmed.
Goal for this chapter: by the end of this chapter you will know what the iMac M4 is, what the most important parts are called, and what you need to have ready before you switch the iMac on for the first time.
Why this matters: starting calmly saves time later. If you know the names of ports, where to find the power button, and what an Apple ID is, the whole setup flow becomes far less stressful.
The iMac is a complete desktop computer made by Apple. Unlike a laptop, everything is built into one neat unit: a high-quality screen, the computer brain (the M4 chip), a camera for video calls, speakers, and microphones. You connect a keyboard and either a mouse or the trackpad — these items usually come with the iMac.
The M4 is Apple’s name for the small silicon chip inside the iMac that acts as the computer’s brain. For readers who prefer technical detail: Apple’s M4 chip in the current iMac models is an Apple Silicon system-on-chip that combines processing cores, graphics cores and a dedicated Neural Engine for tasks such as smart photo editing and video processing; Apple lists core counts and media features on its official technical page.
Put simply: the M4 helps the iMac do things quickly while still using less power than older machines. That means faster apps and smoother video calls for everyday uses like email, internet browsing, photos and video chat.
When you look at the iMac for the first time, these are the features to know and where to find them.
Power button — typically on the rear of the screen. You press this to wake the iMac or to shut it down. Apple’s setup guide shows precisely where to press and the first on-screen prompts you’ll see.
Camera, microphone and speakers — these are built into the top edge and body of the iMac. They let you make video calls and record sound without any extra equipment.
Ports — look at the back and underside for USB-C / Thunderbolt ports, an Ethernet option (on some models) and the power connection. The exact arrangement depends on the model you have. Apple publishes model-specific port layouts on its technical pages.
Keyboard and pointing device — Apple sends a Magic Keyboard and either a Magic Mouse or Magic Trackpad. The keyboard will show the Command and Option keys used often in macOS; don’t worry — we’ll explain those keys in detail later.
Screen — the iMac’s display is a high-resolution Retina screen and may be listed as 4.5K in Apple documents. The display produces sharp text and clear photos, which helps older eyes. The iMac model page lists the exact display size and resolution for your model.
Before you press the power button for the first time, gather a few items and check a couple of household things. This saves time and frustration.
Have to hand: • Your Wi-Fi name and Wi-Fi password. • An Apple ID and password if you already use one. If you don’t have one, don’t worry — the setup process offers a clear way to create it. (We’ll step through that.) • A charged phone, if you plan to use your iPhone to speed up signing in. Modern Macs allow you to use an iPhone during setup to transfer settings and passwords safely.
Check in the room: • A comfortable desk and chair at a height where your forearms are close to horizontal when you rest them on the desk. • A clear socket to plug the iMac into; avoid extension cables with other heavy appliances on the same line while you first install. • Good natural light so you can follow small text in prompts — but avoid placing the iMac where the sun will strike the screen directly and cause glare.
If you follow the next chapter’s setup steps slowly and patiently, within an hour you will likely be able to: • Turn the iMac on and complete the setup assistant prompts. • Connect to your home Wi-Fi network. • Sign in with an Apple ID or create one. • Adjust basic display size and pointer speed for comfort. • Make a test FaceTime call or send an email to a family member.
These are sensible, practical goals that set you up for the rest of the guide.
It helps to know a small number of names. Here they are with short UK-English definitions that are easy to remember.
Apple ID — your personal account that connects you to Apple services such as the App Store, iCloud, FaceTime and the Mac App Store. You need it to download apps and to keep files in iCloud.
iCloud — Apple’s online service for storing photos, documents and backups. It keeps items in sync between your iPhone, iPad and Mac if you switch it on.
Finder — the app on a Mac you use to find and organise files and folders, similar to File Explorer on other machines.
System Settings — the place where you change how the Mac behaves. In older guides this was called System Preferences; Apple has been updating the name and layout across recent macOS releases.
Accessibility — the collection of settings that make the Mac easier to use for people with hearing, sight or motor differences. Apple’s accessibility pages describe features such as Live Captions, VoiceOver and Magnifier, which we will use in chapter five.
Do this exercise before you switch on the iMac. It helps make the first minute of setup less scary.
Exercise: take two minutes to write down in large clear letters — on a notepad or typed into your phone — the name of your Wi-Fi network and the Wi-Fi password. If you don’t know it, ask the person who manages your home internet. If the Wi-Fi network is provided by your internet provider, the default name and password are often printed on the bottom of the router device; write that down.
Why this helps: during setup you will be asked for a Wi-Fi network and its password. Having that information to hand speeds the process and reduces stress.
Throughout this manual I will use a consistent structure that is designed for readers who prefer steady steps: • A clear learning goal at the start of each chapter. • Short, numbered steps for hands-on tasks — easy to follow and easy to tick off. • Small practice activities to build confidence. • Troubleshooting boxes that tell you what to try next if something does not go to plan. • A final checklist so you can be certain you finished the work for that chapter.
Each chapter ends with a short paragraph that suggests what to try next, so the learning feels like a gentle walk rather than a race.
I have used official Apple technical pages and Apple support documentation to confirm the iMac’s hardware features and the official setup flow. The iMac technical specifications and setup instructions are described on Apple’s product and support pages. The accessibility features such as Live Captions, VoiceOver and Read & Speak (spoken content) are described on Apple’s accessibility pages and have been updated in 2025 releases to include improved Magnifier and other hearing and vision features. For readers who want to check official details, these sources are available online: Apple’s iMac technical page and the iMac setup and accessibility guides.
Chapter Two will be a calm, screenshot-rich unboxing and placement guide. It will assume you are sitting at a desk, and will walk you through every single step — taking the iMac out of its box, placing it on the desk correctly, connecting the power lead safely, placing the keyboard and mouse or trackpad, and plugging the iMac into power. It will include large-type lists and safety tips for seniors, and it will show where the power button and connection ports are located. That chapter will include short practice drills you can do while the iMac powers up.
If you are ready I will proceed to Chapter Two next and include screen-by-screen setup guidance for the Setup Assistant. If you want me to start drafting Chapter Two immediately, I’ll include extra verification steps pulled from Apple’s official “Set up your iMac” guide and the migration options when using an iPhone or iPad during setup.
Quick checklist — Chapter One completion
□ I know where to find the power button. □ I have my Wi-Fi name and password written down. □ I have a note of my Apple ID or I know how to create one. □ I understand that the M4 is the chip inside the iMac and I know one place to check model details (Apple’s technical specs page).
Learning goal: By the end of this chapter you will be able to unbox your Apple iMac with confidence, place it safely on your desk, connect the power cable correctly, and adjust the screen height and position for comfortable use. You’ll also tick off a simple checklist to ensure nothing is missed.
Before you lift the lid, it’s helpful to know exactly what should be inside the box. That way you can be sure nothing is missing, and you’ll feel more comfortable moving ahead. According to Apple’s published “In the Box” list for the iMac, you should expect the following items:
Step-by-step check when you open the box:
Carefully open the top flap of the box (use two hands) and lift out the iMac unit — keep the box lid nearby, you’ll need it for cables.
Remove the foam or protective wrap carefully so you don’t scratch the screen.
Locate the smaller box(es) inside which contain the keyboard, mouse/trackpad, cables.
Lay out all items on a clear desk or table so you can check them off one by one.
Use a printed or digital tick-list (you can create one) to mark each item as present.
Why this matters for seniors or new users:
