The Complete macOS Catalina Manual

Master macOS Catalina with Confidence

Apple’s macOS 10.15 Catalina brought a wave of changes, from the end of iTunes to the arrival of Sidecar and Screen Time. This complete manual walks through what is new, what has changed, and how to get the most from your Mac every day.

New Catalina Features, Explained

The manual begins with the headline updates. Learn how the Music app replaces iTunes for your audio library, how the TV app handles movies and shows, and how Podcasts keeps subscriptions organised. Discover how Find My helps locate friends and Apple devices, how Sidecar turns your iPad into a second screen or drawing tablet, and how Screen Time gives you a clear view of Mac usage.

Core Mac Skills for New and Upgrading Users

From first-time setup to everyday navigation, the guide covers the fundamentals. Set up Wi-Fi and Ethernet, master trackpad gestures, understand the desktop, and organise files with Finder. The Dock, Spotlight search, Notification Centre, and Dark Mode are all explained in plain language.

Essential Apps in Depth

Dedicated sections explore the apps you use most. Safari, Mail, Photos, Contacts, Calendar, Reminders, Messages, Books, FaceTime, Maps, and the App Store are broken down with practical tips. Whether you are tweaking email settings, organising a photo library, or planning events, the steps are clear and easy to follow.

Productivity, Continuity, and Troubleshooting

The later chapters focus on working smarter. Use iCloud for storage and syncing, Mission Control for window management, Handoff and Continuity to move between Mac and iPhone, Split View for multitasking, and Siri for voice commands. A dedicated troubleshooting and maintenance section helps you keep your Mac running smoothly, back up with Time Machine, and customise keyboard shortcuts.

With a glossary of Mac and computing terms and plenty of step-by-step instructions, this manual is a practical companion for anyone using macOS Catalina.
