Take Control of
Maintaining Your Mac

Third Edition
Joe Kissell

Learn how to prevent problems with your Mac and keep little irritations from turning into major headaches. Joe Kissell shows you a simple maintenance regimen that will keep your Mac humming. It starts with a good spring cleaning and then adds simple daily, weekly, monthly, and yearly tasks, as well as ongoing monitoring.

All Take Control books are delivered in two ebook formats—PDF and EPUB—and can be read on nearly any device.

Note: This book is appallingly outdated. It requires not merely a total overhaul but a rethinking from scratch. Among many other things, it has to support newer Macs with M-series processors, Macs using the APFS file system, and the latest hardware and software. In its current state, we can’t stand behind its advice anymore. Our plan is to create a single new book from scratch that covers maintaining, troubleshooting, and speeding up Macs (thus replacing three separate titles with one). It will draw on the old books to some extent but offer greatly updated and simplified advice. We hope, but do not promise, to release it in the first quarter of 2024. (Read more about updates).)

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your car’s oil periodically to prevent engine damage, you should eliminate the crud on your Mac (whether that’s dust, outdated apps, or useless files) and perform other tasks to keep it healthy.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.

What You’ll Learn:

  • Keeping Software Up to Date: Figure out what software on your Mac is out of date, whether automatic updates are a good idea, and how to keep up with the latest bug fixes.
  • Removing Digital Clutter: Find and remove old software, useless files, unneeded login items, and other items that can take up valuable space and cause performance issues.

  • Using Maintenance Utilities: Find out which maintenance apps are most useful, which should be avoided, and what to watch out for when using third-party utilities.
  • Daily, Weekly, Monthly, & Yearly Tasks: Performing quick and easy maintenance tasks on a regular schedule can prevent small problems from turning into major disasters.
  • Maintenance Myths: Conventional wisdom is often wrong. Don’t waste time or effort on maintenance tasks that most people can safely avoid.
  • Preparing for a macOS Upgrade: Apple is now upgrading macOS on a yearly schedule. Find out what you need to know to be ready for the next major release.
