Italics

Italic type introduces and defines a new term.

Start an Application

To perform tasks of any kind in macOS, you use one of the applications installed on your Mac. The application you use depends on the task you want to perform. For example, if you want to surf the World Wide Web, you use a web browser application, such as the Safari program that comes with macOS. Before you can use an application, however, you must first tell macOS what application you want to run. macOS launches the application and displays it on the desktop. You can then use the application’s tools to perform your tasks.

Start an Application Using Launchpad

You can start an application using the Launchpad feature. This is often faster than using the Applications folder, particularly for applications that do not have a Dock icon.

Launchpad is designed to mimic the Home screens of the iPhone, iPad, and iPod touch. So if you own one or more of these devices, then you are already familiar with how Launchpad works.

Locate the Mouse Pointer

Your Mac includes a feature that helps you locate the mouse pointer. This is useful because although you can control certain features of macOS using the keyboard or by using gestures on a trackpad or similar device, most macOS tasks require the mouse or trackpad. Clicking, double-clicking, dragging, and other standard mouse techniques make using macOS easy and efficient, but not if you have trouble locating the mouse pointer. This can happen very easily if your screen is crowded with windows.

Switch Between Applications

If you plan on running multiple applications at the same time, you need to know how to easily switch from one application to another. In macOS, after you start one application, you do not need to close that application before you open another one. macOS supports a feature called multitasking, which means running two or more applications simultaneously. This is handy if you need to use several applications throughout the day.

View Running Applications with Mission Control

The Mission Control feature makes it easier for you to navigate and locate your running applications. macOS allows you to open multiple applications simultaneously, and the only real limit to the number of open applications you can have is the amount of memory contained in your Mac. In practical terms, this means you can easily open several applications, some of which may have multiple open windows. To help locate and navigate to the window you need, use the Mission Control feature.

Run an Application Full Screen

You can maximize the viewing and working areas of an application by running that application in full-screen mode. When you switch to full-screen mode, macOS hides the menu bar, the application’s status bar, the Dock, and the top section of the application window (the section that includes the Close, Minimize, and Zoom buttons). macOS then expands the rest of the application window so that it takes up the entire screen. Note that not all programs are capable of switching to full-screen mode.

Split the Screen with Two Applications

You can make your macOS desktop more convenient and more efficient by splitting the screen with two application windows. This is called Split View and it means that macOS switches to full-screen mode, where one application window takes up the left side of the desktop, and a second application window takes up the right side of the desktop. With these windows arranged side by side, the content of both windows remains visible at all times, so you can easily refer to one window while working in the other.

Search Your Mac

You can save time and make your Mac easier to use by learning how to search for the apps, settings, or files that you need.

After you have used your Mac for a while and have created many documents, you might have trouble locating a specific file. You can save a great deal of time by using the macOS Spotlight search feature to search for your document. You can also use Spotlight to search for apps as well as information from the Internet, the iTunes Store, the App Store, and more. Alternatively, you can use Finder’s Search box to search just your Mac.

Voice-Operate Your Mac with Siri

If your Mac comes with a built-in microphone or if you have connected a headset or microphone to your Mac, you can use the Siri voice-activated assistant to control macOS. You can use Siri to search your Mac, search the web, and start apps. You can also use Siri to run commands within certain apps. For example, you can use Siri to schedule appointments, start an email, or display a contact.

Before you can use Siri, you must have a microphone — either one that comes with your Mac or one that you connect to your Mac — and you must enable Siri in System Preferences.

Save a Document

After you create a document and make changes to it, you can save the document to preserve your work. When you work on a document, macOS stores the changes in your computer’s memory. However, macOS erases the contents of the Mac’s memory each time you shut down or restart the computer. This means that, unless the app you are using saves changes automatically, as many now do, the changes you make to your document are lost when you turn off or restart your Mac. Saving the document preserves your changes on your Mac’s hard drive.

Open a Document

To work with a document that you have saved in the past, you can open it in the application that you used to create it. When you save a document, you save its contents to your Mac’s hard drive, and those contents are stored in a separate file. When you open the document using the same application that you used to save it, macOS loads the file’s contents into memory and displays the document in the application. You can then view or edit the document as needed.
