Every September, Apple holds a press conference to get us excited about the newest gadgets that are certain to suck your wallets dry. The 2018 event, of course, introduced us to the latest Apple Watch and iPhone. This year, however, Apple proved it wasn't quite done yet. In October, it held a conference to remind everyone of something that many had forgotten: The MacBook Air. It had been 10 years since Steve Jobs wowed us all by pulling a laptop out of an envelope; and it had been 5 years since the last update to the slim computer. Apple never stopped selling Airs, but most assumed its days were numbered-it's power, graphics, and design just didn't cut it anymore. Then October came, and Apple proudly reminded everyone that it had not forgotten about the once beloved device. It introduced a new MacBook Air with all the features you'd expect from a modern slim computer: retina display, top of the line processor, memory, and amazing battery life. MacBook Air was suddenly relevant again. If you have purchased the notebook or are just curious about seeing more about what Mac OS can do for you, then you'll see it in this book. This book is intended for people who want to get started quickly with the MacBook Air. For that reason, it's not as comprehensive as other guides. If you want to know about some feature buried deep under the hood that you'll never use, then there are other books for you--I'm sure they'll make good doorstops when you finish. If you just want a simple guide that tells you what you need to know, so you can use your computer already, then this book is for you. If you're new to Mac--perhaps switching over from Windows, then this book will help you figure out all the similarities and differences; because so many people come to Mac from Windows, this book is written in a way to help with that transition. I purposely have done my best to make this handbook a little more casual and fun then what you expect from most Mac OS manuals. Mac OS is an operating system, and any guide you read should be an equally fun read. Each chapter starts with bullet points on what will be covered, so if something you already know, you can skip right ahead; if you only need to know how to use new features, the book is also formatted in a way that these stand out. Are you ready to start enjoying the new Mac OS? Then let's get started!
