With FileVault 2, your data is safe and secure — even if your Mac falls into the wrong hands. FileVault 2 encrypts the entire drive on your Mac, protecting your data with XTS-AES 128 encryption. Mac computers built on the Apple M1 chip take data protection even further by using dedicated hardware to protect your login password and enabling. The hole under the power cord is a security slot for a lock down cable to secure your imac to a table, bookcase etc. Maybe you have previously used soundflower for recording internal audio, and then realized there are problems with audio flower and Mac OS Catalina. The current Mac operating system is macOS, originally named 'Mac OS X' until 2012 and then 'OS X' until 2016. Developed between 1997 and 2001 after Apple's purchase of NeXT, Mac OS X brought an entirely new architecture based on NeXTSTEP, a Unix system, that eliminated many of the technical challenges that the classic Mac OS faced.

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.

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.

Mac

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

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.

Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by a product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
