This book contains hundreds of macOS tips, tricks, and secrets. It is a true power user's guide, without wasting time on the 'fluff' that you will not use. If you are a new or intermediate user you can move quickly to the rank of a power user. For the more experienced users coming from another platform (i.e. Linux and Windows), I explain what you need to know to help you get started faster and overcome nuances with the OS that might drive you nuts until you realize how to overcome them. I also include troubleshooting guides for problems, and a command terminal reference to exposing hidden utilities and functionality that you may never even know that they are there. I also help you leverage the power of features like Siri and give a deeper appreciation of the technology by allowing it to help you with things that you did not know it could do. I also include very robust and up-to-date keyboard shortcuts reference, to help you leverage features of the operating system that might only be available from the keyboard or hidden in the menus. I try to make this book fun and balanced by sharing my expertise and opinions on why a feature works in the specific way it does.
