This guide will help you become familiar with Mac OS X — the operating system of every Mac. In just a few, short steps, this article will teach you everything you need to know to get started with your Mac.

Mac OS X — The Basics

Mac OS X is the operating system of your Mac. It’s the basic system that enables your Mac to work. All the files, folders and programs are handled by Mac OS X as well as internet connectivity, battery consumption and more.

Applications written with Carbon were initially able to run natively on both classic Mac OS and Mac OS X, although this ability was later dropped as Mac OS X developed. Carbon was not included in the first product sold as Mac OS X: the little-used original release of Mac OS X Server 1.0, which also did not include the Aqua interface.

Mac OS X — The Basics. Mac OS X is the operating system of your Mac. It’s the basic system that enables your Mac to work. All the files, folders and programs are handled by Mac OS X as well as internet connectivity, battery consumption and more. As a Mac user, you will encounter Mac OS X in many different forms: When viewing the desktop. Make games, stories and interactive art with Scratch. Mac OS X is a Unix-like operating system developed by Apple for their Mac hardware line. Windows is a series of operating systems, running their own proprietary kernel, that is developed by Microsoft and licensed to various computer manufacturers. Mac-on-Linux is a Linux/PPC program that virtualizes MacOS or MacOSX in Linux.

As a Mac user, you will encounter Mac OS X in many different forms:

  • When viewing the desktop
  • When you’re browsing through files
  • Through the Mac’s search function (called “Spotlight”)
  • Through the application bar (called “The Dock”)
  • As the system that runs your applications

…and much more. Mac OS X is always there in the background, making sure your Mac runs smoothly. By learning more about Mac OS X, you will become a more efficient and confident Mac user. Let’s get started!

Mac OS X — An Overview

The home of your Mac is the desktop. Think of it as a physical desktop – a place where you may temporarily spread out your work while performing a task.

For example, you may put an image from the internet on the desktop, make some modifications, and then drag it into an email. Just remember, while the desktop is a great workspace it not a good place to store files long-term since it quickly gets messy — again, just like an actual desktop.

Let’s have a look at the other things you see in when you first turn on your Mac.

The Dock

In the bottom of your screen, you should see “the Dock” — a bar with convenient shortcuts to your favorite applications. If you don’t see it by default, try moving your cursor to the bottom of the screen and it should pop right up.

The icons in the Dock are just shortcuts. You can add or remove icons from the Dock without affecting the actual applications.

To add an application shortcut to the dock, you can use Launchpad, which is a complete overview of all your applications. You can probably find Launchpad in the left part of your Dock. Click Launchpad to view all your applications, then drag any icon into the dock to create a new shortcut.

Another way to add shortcuts to the Dock is to find the Application file (in the Applications folder) and drag it to the Dock. This requires some familiarity with browsing through files.

To remove an item from the dock, just drag it out and hold it over the desktop. After a second or so, a “remove” label shows up. Release the icon and the application shortcut is removed from the Dock.

Menus

At the top of the screen you will see some menus. These menus change depending on what application you are using at the moment.

If there is ever anything you want to do in a certain application, try to find it in these menus.

Menu extras

Look at the top of your screen. To the right of the menus you are most likely to see a few symbols.

These little icons are mostly used to quickly edit your Mac’s settings. Rather than having to open System Preferences, you can change the settings using Menu extras.

To change what Menu extras are visible, open System preferences. Click a preference pane and look for the checkbox that lets you choose if you want the specific Menu extra to be visible or not.

Users

Mac OS X offers a really nice way to switch between the different user accounts on the Mac. Near the upper right corner of your screen you will find your name. Click it and a list of all the users on the computer will appear.

Now, just click another user in order to log in to his/hers account (password may of course be required).

Spotlight

If you look at the upper right corner of your screen, you will see a small magnifying glass. This is Mac OS X’s search function. It is called Spotlight. To read more about it, click here.

Dashboard

The

Mac OS X has a great thing called Dashboard where you can run mini-applications called widgets. Read the article about it, Dashboard is awesome.

Every major version of Mac OS X macOS has come with a new default wallpaper. As you can see, I have collected them all here.

While great in their day, the early wallpapers are now quite small in the world of 5K and 6K displays.

10.0 Cheetah & 10.1 Puma

The first two releases of Mac OS X shared the same wallpaper. The sweeping blue arcs and curves helped set the tone of the new Aqua interface.

10.2 Jaguar

Jaguar took the same Aqua-inspired theme but added some depth and motion to things. In my head, the trails streaking across the screen were from a set of comets.

10.3 Panther

While Panther inflicted Macs everywhere with Brushed Metal, its wallpaper stayed on brand, refreshing the original 10.0 image.

10.4 Tiger

Many consider Tiger to be the best “classic” version of Mac OS X. While that may or may not be true, it is my favorite Aqua-inspired wallpaper.

10.5 Leopard

Complete with a revised, unified user interface and shiny new Dock, 10.5 broke the Aqua mold. As such, Leopard was the first version of OS X to break from the Aqua-themed wallpaper. It ushered in the “space era” of OS X wallpapers, which was used heavily in the new Time Machine interface as well.

10.6 Snow Leopard

The “no new features” mantra for Snow Leopard didn’t ban a new wallpaper, thankfully. This starscape is still one of my favorites.

10.7 Lion

Lion kept up the space theme, this time showing off the Andromeda galaxy. The space nerd in me likes the idea, but the execution of this one leaves dead-last on my list of favorites.

10.8 Mountain Lion

Just like Snow Leopard before it, with Mountain Lion, Apple opted to clean up and revise the existing theme as opposed to changing directions for what would be a less-impactful release of OS X.

10.9 Mavericks

Mavericks marked the beginning of Apple’s “California location” naming scheme for Mac releases. The wave depicted looks as intimidating as the ones in the famous surfing location.

macOS Catalina brought big changes to the Mac, including the ability to run iPad apps natively, opening the platform up to a much larger number of developers than ever before.
