Understanding MacOS: An Overview

MacOS is globally known for its user-friendly interface and native applications optimized for performance. Its core is built on a UNIX-based system, providing stability and efficiency. Since the launch of the first MacOS, then termed Mac OS X in 2001, Apple has been consistent in releasing updates and new versions, each with new features and performance enhancements.

The current version of MacOS is MacOS Monterey, released in 2021. Previous well-known versions include Big Sur, Catalina, Mojave, High Sierra, and Sierra. Each new version aims to optimize users' experiences with unique features and improved performance.

Getting Started with MacOS

The initial time you boot up your new device, MacOS welcomes you with a setup assistant. It guides you through setting up account details, including your Apple ID, which links you to Apple services like the App Store and iCloud.

By default, the Dock contains icons for common applications, such as Safari, Mail, Music and FaceTime. However, you can personalize the Dock by adding or removing apps as per your preference.

The Finder located on the left of the Dock is a powerful tool that lets you organize and manage your files, programs, storage disks, network servers, and more.

Another useful feature to boost productivity is Mission Control, which gives a bird’s eye view for managing multiple windows, apps, or documents.
