Set up a rock-solid backup strategy so that you can restore quickly and completely, no matter what catastrophe arises. Version 4.1, updated November 19, 2021 Joe Kissell provides the advice you need to create a Mac backup strategy that protects your data and enables quick recovery. He compares backup software, services, and media to help you make the best choices. You'll learn to set up, test, and maintain backups, plus how to restore files after a calamity! Creating and maintaining a solid backup plan is essential to anyone who uses a Mac, in order to prevent the loss of important data if disaster strikes--whether through hardware or software failure, theft, human error, or other mishap. In Take Control of Backing Up Your Mac, Fourth Edition, tech expert Joe Kissell explains how to design a sensible backup strategy, choose and configure the best backup hardware and software for your needs, and understand how to make your backups as painless as possible. His advice is equally useful to those who have never had a backup system and those whose backup systems are in need of an update. The fourth edition, a major rewrite, fully delves into the new challenges presented by Big Sur and Monterey, M-series Macs, and the ever-changing landscape of Mac backup hardware, software, and cloud services. It features entirely rethought advice about bootable (and non-bootable) duplicates, backup media, and disk formats, as well as changes in Time Machine and the weird world of APFS snapshots. This book covers macOS 10.14 Mojave through macOS 12 Monterey. Using this book, you'll learn how to: Design (or update) the ideal backup system: If you're starting from scratch, you'll find all the information necessary to assemble a reliable and easy-to-use backup system. If you're updating an existing system, you'll learn about what's new in hardware, software, and online services that might affect the way you back up your Mac in the future. Choose backup software: Apple's Time Machine is both free and easy to use, but it's not the best choice for everyone, and even if you do use Time Machine, you'll certainly want to supplement it with other tools. You'll learn about key features to look for in a backup app and find tips on using several popular tools. You'll also discover the pros and cons of cloud backup services, and get help choosing the right one. (An online appendix covers dozens of apps and services.) Shop for hardware: Depending on your needs and goals, you may n ...

Set up a rock-solid backup strategy so that you can restore quickly and completely, no matter what catastrophe arises. Version 5.0.1, updated February 19, 2024 Joe Kissell provides the advice you need to create a Mac backup strategy that protects your data and enables quick recovery. He compares backup software, services, and media to help you make the best choices. You’ll learn to set up, test, and maintain backups, plus how to restore files after a calamity!n Creating and maintaining a solid backup plan is essential to anyone who uses a Mac, in order to prevent the loss of important data if disaster strikes—whether through hardware or software failure, theft, human error, or other mishap. In Take Control of Backing Up Your Mac, Fifth Edition, tech expert Joe Kissell explains how to design a sensible backup strategy, choose and configure the best backup hardware and software for your needs, and understand how to make your backups as painless as possible. His advice is equally useful to those who have never had a backup system and those whose backup systems are in need of an update. The book delves into the challenges presented by recent versions of macOS, M-series Macs, and the ever-changing landscape of Mac backup hardware, software, and cloud services. It explains what you need to know about bootable (and non-bootable) duplicates, backup media, and disk formats, as well as recent changes in Time Machine and the weird world of APFS snapshots. It also shows you how to include in your backups files and folders that are stored in the cloud, even if there's no local copy of them. Using this book, you’ll learn how to: • Design (or update) the ideal backup system: If you’re starting from scratch, you’ll find all the information necessary to assemble a reliable and easy-to-use backup system. If you’re updating an existing system, you’ll learn about what’s new in hardware, software, and online services that might affect the way you back up your Mac in the future. • Choose backup software: Apple’s Time Machine is both free and easy to use, but it’s not the best choice for everyone, and even if you do use Time Machine, you’ll certainly want to supplement it with other tools. You’ll learn about key features to look for in a backup app and find tips on using several popular tools. You’ll also discover the pros and cons of cloud backup services, and get help choosing the right one. (An online appendix covers dozens of apps and services.) • Shop for hardware: Depending on your needs and goals, you may need one or more external SSDs or hard drives, but the range of options (sizes, interfaces, speeds, and more) can be bewildering. Joe helps you find the best backup hardware, whether it’s individual SSDs or hard drives, RAIDs, NAS devices, or other options. • Make and maintain backups: Once you’ve selected hardware and software, you’ll need to know how to make your first backup, set up your backups to run unattended, and test them regularly to make sure they’re working as they should. This includes both versioned backups (which contain old file versions and deleted files) and—for some users—bootable or non-bootable (data-only) clones. And, you’ll learn about strategies for keeping extra backups offsite. • Operate Time Machine: If you choose Time Machine for versioned backups, you’ll learn how to back up and restore individual files, app-specific data (such as contacts), and even an entire disk. You’ll also discover why and how to encrypt Time Machine backups, how APFS snapshots work (inside and outside Time Machine), and what to do if Time Machine misbehaves. • Deal with unusual backup needs: If you deal with exceptionally large files (such as audio and video files), spend a lot of time on the road away from your usual backup hardware, run Windows on your Mac, or rely on cloud services to store essential data, you’ll want to take extra (or different) steps to make sure everything is safely backed up. You’ll also learn various approaches to backing up and restoring data from Apple’s Notes app. • Manage your media: What happens when a backup drive fills up, or becomes so old that you worry about its future reliability? What if you want to archive older files for posterity, but not necessarily maintain them as part of your daily backups? Joe explains how to deal with media management tasks such as these. • Recover lost data: Backing up data can be easy, but restoring it is often more challenging. When you discover that data is missing—whether due to a disk error, theft, or a simple mistake—you need to know the exact steps needed to recover it and get back to work as soon as possible.

Overcome password frustration with Joe Kissell's expert advice! Version 4.1.1, updated March 21, 2024 Password overload has driven many of us to take dangerous shortcuts. If you think ZombieCat12 is a secure password, that you can safely reuse a password, or that no one would try to steal your password, think again! Overcome password frustration with expert advice from Joe Kissell! Passwords have become a truly maddening aspect of modern life, but with this book, you can discover how the experts handle all manner of password situations, including multi-factor authentication that can protect you even if your password is hacked or stolen. The book explains what makes a password secure and helps you create a strategy that includes using a password manager, working with oddball security questions like "What is your pet’s favorite movie?", and making sure your passwords are always available when needed. Joe helps you choose a password manager (or switch to a better one) in a chapter that discusses desirable features and describes nine different apps, with a focus on those that work in macOS, iOS, Windows, and Android. The book also looks at how you can audit your passwords to keep them in tip-top shape, use two-step verification and two-factor authentication, and deal with situations where a password manager can’t help. New in the Fourth Edition is complete coverage of passkeys, which offer a way to log in without passwords and are rapidly gaining popularity—but also come with a new set of challenges and complications. The book also now says more about passcodes for mobile devices. An appendix shows you how to help a friend or relative set up a reasonable password strategy if they're unable or unwilling to follow the recommended security steps, and an extended explanation of password entropy is provided for those who want to consider the math behind passwords. This book shows you exactly why: • 9-character passwords with upper- and lowercase letters, digits, and punctuation are not strong enough. • You cannot turn a so-so password into a great one by tacking a punctuation character and number on the end. • It is not safe to use the same password everywhere, even if it’s a great password. • A password is not immune to automated cracking because there’s a delay between login attempts. • Even if you’re an ordinary person without valuable data, your account may still be hacked, causing you problems. • You cannot manually devise “random” passwords that will defeat potential attackers. • Just because a password doesn’t appear in a dictionary, that does not necessarily mean that it’s adequate. • It is not a smart idea to change your passwords every month. • Truthfully answering security questions like “What is your mother’s maiden name?” does not keep your data more secure. • Adding a character to a 10-character password does not make it 10% stronger. • Easy-to-remember passwords like “correct horse battery staple” will not solve all your password problems. • All password managers are not pretty much the same. • Passkeys are beginning to make inroads, and may one day replace most—but not all!—of your passwords. • Your passwords will not be safest if you never write them down and keep them only in your head. But don’t worry, the book also teaches you a straightforward strategy for handling your passwords that will keep your data safe without driving you batty.

Set up a rock-solid backup strategy so that you can restore quickly and completely, no matter what catastrophe arises. Read along as backup guru Joe Kissell helps you understand the three components of a solid backup strategy, implement that strategy in a way that meets your specific needs, and understand the hows and whys of what you are doing, taking you far beyond the limited security of turning on Time Machine or copying a few files to a flash drive or cloud service. You'll also find details on how to test your backup system, and on how to restore from backup. Whether you're running Mac OS X 10.7 Lion or 10.8 Mountain Lion, you'll soon have a reliable, up-to-date backup system. Although the 200-page ebook is organized so you can start backing up without reading every page, the full ebook will teach you to:• Design a reliable backup system. If you're developing a new backup system, you'll learn how to make it not only thorough, ensuring that all your data is safe, but also easy to manage and appropriate for your situation. If you're assessing an existing backup system, Joe discusses how to evaluate it and offers guidance for improving and modernizing it.• Talk like an expert. You'll learn the meaning of terms like "versioned backups," "delta encoding," "push" and "pull" backups, "duplicates," "server," "client," "incremental," "hard link," "mirroring," and "snapshot."• Choose backup software. Consider the pros and cons of Apple's free Time Machine and determine whether it's a good match for you--or if you should consider a different program with better features for your needs. You'll learn about 14 key features to look for in backup apps and find overviews and tips for 8 noteworthy products (an online appendix covers nearly 100 options), plus several suggestions for online backups. You'll also get Joe's recommendations to help you sort through the possibilities.• Shop for hardware. You'll discover the pros and cons of backup media options such as hard drives (with USB, FireWire, eSATA, or Thunderbolt interfaces--and with or without full-disk encryption), flash drives, optical media, tape drives, RAIDs, Drobo storage devices, Time Capsules, and NAS and SAN devices.• Operate Time Machine. Find out what goes on beneath Time Machine's simple surface, and how best to make use of Apple's built-in backup system, including how local snapshots work when your Time Machine volume isn't available, and how to encrypt a Time Machine backup.• Make backups. No matter what backup software you decide to use, Joe provides a conceptual walk-through of the entire process, offering basic information for people who've never made a backup before and savvy, real-world suggestions for making the backup process as easy as possible.• Deal with special backup needs. You'll learn what to do about certain kinds of data that may require special backup strategies, such as large media archives, frequently changing files that need special versioned backup treatment, and Windows files and volumes hosted on your Mac.• Manage your media. Diamonds may be forever, but backup devices are not. Disks fill up. They also wear out. Find advice for handling those realities.• Recover lost data. Use your backup to recover lost data successfully in the event of a hard disk crash or other calamity. After all, restoration is what's really important. Teach This Book: Once your backups are humming along reliably, can we encourage you to help your friends, family, and colleagues improve their backups before they lose data? This ebook links to a downloadable one-page PDF handout and PDF-based slides that you can present on any computer or mobile device screen.

Learn what’s private online (not much)—and what to do about it! Updated 04/11/2019 Nowadays, it can be difficult to complete ordinary activities without placing your personal data online, but having your data online puts you at risk for theft, embarrassment, and all manner of trouble. In this book, Joe Kissell helps you to develop a sensible online privacy strategy, customized for your needs. Whether you have a Mac or PC, iOS or Android device, set-top box, or some other network-enabled gadget, you’ll find practical advice that ordinary people need to handle common privacy needs (secret agents should look elsewhere). You’ll learn how to enhance the privacy of your internet connection, web browsing, email messages, online chatting, social media interactions, and file sharing, as well as your mobile phone or tablet, and Internet of Things devices like webcams and thermostats. Parents will find important reminders about protecting a child’s privacy. The book also includes Joe’s carefully researched VPN recommendations. The book is packed with sidebars that help you get a handle on current topics in online privacy, including international travel, quantum computing, why you should beware of VPN reviews online, two-factor authentication, privacy and your ISP, understanding how ads can track you, and more. You’ll receive savvy advice about topics such as these: • Why worry? Learn who wants your private data, and why they want it. Even if you don’t believe you have anything to hide, you almost certainly do, in the right context. Would you give just anyone your financial records or medical history? Didn’t think so. • Set your privacy meter: Develop your own personal privacy rules—everyone has different privacy buttons, and it’s important to figure out which matter to you. • Manage your Internet connection: Understand privacy risks, prevent snoops by securing your Wi-Fi network, and take key precautions to keep your data from leaking out. Also find advice on using a VPN, plus why you should never believe a VPN review that you read on the Internet—even if it seems like it was written by Joe! • Browse and search the web: Learn what is revealed about you when you use the web. Avoid bogus websites, connect securely where possible, control your cookies and history, block ads, browse and search anonymously, and find out who is tracking you. Also, take steps to protect passwords and credit card data. • Send and receive email: Find out how your email could be intercepted, consider when you want email to be extra private (such as when communicating with a lawyer), find out why Joe doesn’t recommend email encryption as a solution to ordinary privacy needs (but find pointers for how to get started if you want to try it—or just encrypt an attachment, which is easier), get tips for sending email anonymously, and read ideas for alternatives to email. • Talk and chat online: Consider to what extent any phone call, text message, or online chat is private, and find tips for enhancing privacy when using these channels. • Watch your social media sharing: Understand the risks and benefits of sharing personal information online (especially on Facebook!), tweak your settings, and consider common-sense precautions. • Share files: What if you want to share (or collaborate on) a contract, form, or other document that contains confidential information? Find out about the best ways to share files via file server, email attachment, cloud-based file sharing service, peer-to-peer file sharing, or private cloud. • Check your electronics: All sorts of gizmos can connect to the Internet these days, so everything from a nannycam to smart light bulbs should be considered in your online privacy strategy. • Think mobile: Ponder topics like SIM card encryption keys, supercookies, location reporting, photo storage, and more as you decide how to handle privacy for a mobile phone or tablet. • Help your children: As a parent, you know a lot about your children, and you have access to lots of photos of them. But that doesn’t mean you should share everything without a thought to your children’s privacy needs. Find a few key tips to keep in mind before you tell all.

Digitize your documents and reduce paper clutter! Version 4.0.1, updated February 2, 2024 The paperless office doesn't have to be a myth! Turn paper into usable digital files, reducing clutter and increasing convenience. This book helps you assess your situation, develop a strategy, and learn clever techniques for keeping more paper at bay—with detailed discussion of the hardware, software, and processes needed to get the job done. Join Joe Kissell as he helps you clear the chaos of an office overflowing with paper. With Joe's guidance you can develop a personal clean-up strategy and choose your tools, including a scanner and the software you need to perform OCR (optical character recognition). You'll also learn about devices and services for storing your digitized documents and document management apps that help you categorize, locate, and view your digital document collections. Once you have your gear in hand, Joe shows you how to convert your paper documents to digitized files and gives you ideas for how to organize your office workflow, explaining how to develop day-to-day techniques that reduce the amount of time you spend pressing buttons, launching software, and managing documents.

Explore everything your Apple Watch can do in watchOS 10! Version 4.2, updated December 13, 2023 Get to know your Apple Watch and customize it to help you focus on what you care about most. Tech expert Jeff Carlson helps you understand the watch mindset, pick the watch model that’s right for you, set up and share its faces and their complications, get the notifications you want, take advantage of the health and fitness features, handle communications, and learn how the controls and core apps work.n The Apple Watch has become the world's best-selling watch, as well as the most popular wearable digital device. Since the device's introduction in 2015, Apple has developed numerous new watch product lines, vastly expanded the device's capabilities, and enabled developers to create entirely new apps and tools. The Apple Watch hides an enormous amount of technical complexity behind that unassuming touch screen, and with help from author Jeff Carlson, you'll unlock every last bit of its power. With watchOS 10, Apple dramatically changed some of the core watch interactions, which Jeff covers here. Take Control of Apple Watch covers all Apple Watch models through Series 9 and Apple Watch Ultra 2, as well as all the new features introduced in watchOS 10. Jeff walks you through getting to know the Apple Watch (including how to pick one out if you haven’t already), along with topics that teach you how to navigate among the watch’s screens with the physical controls, taps on the screen, and Siri. You’ll also find advice on customizing watch faces and sharing them with others; taking advantage of the electrocardiogram (ECG) capability and blood oxygen sensor, plus the temperature sensors introduced in the Series 8 and Ultra; getting the notifications you want; handling text and voice communications; using Apple’s core apps; and monitoring your heart rate, hearing, and monthly cycle to improve your overall health. A final chapter discusses taking care of your Apple Watch, including recharging, restarting, resetting, and restoring. Among the many topics covered in the book are: • Picking out and setting up your own Apple Watch—covers models up through Series 9 and Apple Watch Ultra 2 • How to adapt to the numerous changed gestures in watchOS 10 • Making watch face complications work for you • Using Control Center and Smart Stack • Understanding how the watch interacts with your iPhone (including how to control your watch with your iPhone) • Staying connected using a cellular-enabled Apple Watch model • Using Siri on your watch for a wide variety of tasks • Tracking your exercise, even when you leave your iPhone at home • Using your watch to monitor sleep data • Placing and receiving phone calls on the watch • Getting navigation directions (and using the redesigned Compass app, including waypoints and the Backtrack feature introduced in watchOS 9) • Using the Walkie-Talkie feature to chat with other Apple Watch owners • Sending default (and customized) text messages—and even sending money via Messages • Seeing email from only certain people • Adding calendar events and reminders • Loading your watch with photos and using them to create new watch faces • Doing workouts with Apple Fitness+ • Finding people, devices, and items • Controlling your home with HomeKit-compatible devices • Triggering the iPhone’s camera remotely using the watch • Paying at contactless terminals using Apple Pay • Putting tickets on your watch • Using health-related features such as the blood oxygen sensor and medication reminders, plus the ECG, Cycle Tracking, and Noise apps • Detecting falls and (with newer watch models) car crashes, and automatically calling for help • Controlling an Apple TV, or Music on a Mac with the Remote app • Unlocking a Mac (and authenticating certain actions) with your watch • Adding apps to the watch via your iPhone or the watch's built-in App Store • Resetting a messed-up Apple Watch and force-quitting an app
