Take Control of
Maintaining Your Mac

Note: This book is currently out of date for users of macOS 10.15 Catalina or later. We plan to release a new book in the first quarter of 2022 to provide up-to-date instructions on this topic.

Macs, like all machines, are prone to break down eventually—in either a physical sense (a component going bad) or a logical sense (files becoming corrupted, apps misbehaving). You can reduce the risk of such problems, and minimize the damage when they do occur, with a regular maintenance regimen. This book contains simple steps you can take to keep your Mac humming.

In much the same way that you brush and floss to prevent cavities, or change your car’s oil periodically to prevent engine damage, you should eliminate the crud on your Mac (whether that’s dust, outdated apps, or useless files) and perform other tasks to keep it healthy. By doing so, you’ll improve your Mac’s performance, prevent problems, and increase your productivity.

In this book, best-selling author Joe Kissell helps you start on the right foot by addressing common maintenance issues, and then covers simple tasks you can perform periodically to keep your Mac in top shape. He also helps you discover useful utilities for automating parts of the process and dispels common misconceptions about maintenance.

This book covers 10.9 Mavericks through 10.14 Mojave. It does not cover 10.15 Catalina or later.
