Mac Glossary

The Menu Bar is the horizontal menu area at the top of the macOS screen.

The left side shows menus for the active app, while the right side shows status items such as Wi-Fi, battery, time, and Control Center.

On Mac, many app commands are selected from the Menu Bar rather than from controls inside each window.

The Dock is the app launcher and app-switching area shown at the bottom or side of the macOS screen.

It can contain frequently used apps, currently running apps, recent apps, folders, and the Trash.

It is similar in role to a taskbar, but on macOS it is mainly used as an app launch and switching point.

Finder is the standard macOS app for browsing and managing files and folders.

It is used to move, copy, delete, search, and inspect files, folders, external drives, and network locations.

When checking a working location on Mac, Finder paths and folder structure are often the first things to confirm.

The Desktop is the visible workspace area behind app windows on macOS.

Files and folders can be placed there temporarily, but too many items can make the actual work location unclear.

For production work, it is usually safer to move files into project folders rather than treating the Desktop as long-term storage.

System Settings is the macOS app for changing system-wide settings.

It includes network, Bluetooth, display, keyboard, privacy, security, user, and accessibility settings.

In older versions of macOS, the equivalent app was called System Preferences.

Control Center is a Menu Bar panel for quickly changing common settings such as Wi-Fi, Bluetooth, volume, and display brightness.

It provides quick access without opening System Settings.

On MacBook, it is also useful when checking audio output, display, and connectivity status.

Spotlight is the built-in search feature on macOS.

It can search and open apps, files, folders, emails, and settings.

When the name of an app or file is known, Spotlight can be faster than browsing manually in Finder.

Library is a macOS folder used to store settings, caches, support files, and app-related data.

The user-level Library is located at ~/Library, while the system-level Library is located at /Library.

Because important settings and app data may be stored there, it should not be deleted casually during storage cleanup.

Application Support is a folder where macOS apps store data needed for operation.

A common location is ~/Library/Application Support.

It may contain settings, databases, session data, extensions, workspace information, and other app-specific files.

Terminal is the standard macOS app for working with the command line.

It is used for file operations, Git, development environments, server access, and script execution.

If Finder is the visual entry point for file operation, Terminal is the CLI entry point for controlling the Mac.

The Home Folder is the main folder for the currently logged-in macOS user.

It contains user-specific folders such as Documents, Desktop, Downloads, Pictures, and Library.

In paths, it is often written as ~ or /Users/username.

iCloud Drive is Apple’s cloud file-sync system connected to an Apple ID.

It can sync files across Mac, iPhone, iPad, and the web.

It is convenient for everyday files, but development projects and large working folders need care because sync timing and conflicts can affect work.
