Keep your Mac, iPhone, and iPad safe! Version 1.0, published September 30, 2024 Secure your Mac, iPhone, or iPad against attacks from the internet, physical intrusion, and more with the greatest of ease. Glenn Fleishman guides you through protecting yourself from phishing, email, and other exploits, as well as network-based invasive behavior. Learn about built-in privacy settings, the Secure Enclave, FileVault, hardware encryption keys, sandboxing, privacy settings, Advanced Data Protection, Lockdown Mode, resetting your password when all hope seems lost, and much more.n The digital world is riddled with danger, even as Apple has done a fairly remarkable job at keeping our Macs, iPhones, and iPads safe. But the best security strategy is staying abreast of past risks and anticipating future ones. This book gives you all the insight and directions you need to ensure your Apple devices and their data are safe. You’ll learn about the enhanced Advanced Data Protection option for iCloud services, allowing you to keep all your private data inaccessible not just to thieves and unwarranted government intrusion, but even to Apple! Also get the rundown on Lockdown Mode to deter direct network and phishing attacks, passkeys and hardware secure keys for the highest level of security for Apple Account and website logins, and Mac-specific features such as encrypted startup volumes and FileVault’s login protection process. Security and privacy are tightly related, and this book helps you understand how macOS, iOS, and iPadOS have increasingly compartmentalized and protected your personal data, and how to allow only the apps you want to access specific folders, your contacts, and other information. Here’s what this book has to offer: • Master the privacy settings on your Mac, iPhone, and iPad • Calculate your level of risk and your tolerance for it • Use Apple’s Stolen Device Protection feature for iPhone that deflects thieves who extract your passcode through coercion or misdirection. • Learn why you’re asked to give permission for apps to access folders and personal data on your Mac • Moderate access to your audio, video, screen actions, and other hardware inputs and outputs • Get to know the increasing layers of system security deployed over the past few years • Prepare against a failure or error that might lock you out of your device • Share files and folders securely over a network and through cloud services • Upgrade your iCloud data protection to use end-to-end encryption • Control other low-level security options to reduce the risk of someone gaining physical access to your Mac—or override them to install system extensions • Understand FileVault encryption and protection for Mac, and avoid getting locked out • Investigate the security of a virtual private network (VPN) to see whether you should use one • Learn how the Secure Enclave in Macs with a T2 chip or M-series Apple silicon affords hardware-level protections • Dig into ransomware, the biggest potential threat to Mac users (though rare in practice) • Discover recent security and privacy technologies, such as Lockdown Mode and passkeys

Master the fundamentals of using a Mac! Version 1.0.1, updated May 15, 2025 This book is a thorough, friendly guide to using a Mac, starting from scratch. It covers both the Mac hardware and macOS, as well as Apple’s built-in apps. Whether you're a new to Macs or someone who has been struggling because no one ever taught you the ins and outs, you'll learn how to become a confident Mac user.n Macs don't come with instruction manuals, and most Mac users have never taken a class on all the major concepts, terms, and skills needed to feel comfortable and productive. As a result, it's all too easy to end up cobbling together a sketchy understanding based on trial and error, web searches, and tips from friends and family. This book changes all that. Written by bestselling author Joe Kissell, Mac Basics starts from square one, so even an absolute beginner can follow along. Joe offers a systematic introduction to your Mac's hardware and software, helping you to get oriented, learn your way around, and get answers to the questions that have always puzzled you. But it's not just for newbies! Even people who have been using Macs for years are sure to learn interesting things. The book covers topics such as: • Your Mac's hardware: Learn about all the components of your Mac that you'll interact with, as well as how to use external devices. • What's on the screen: Discover what all the elements on screen are called, what they do, and how to use them. You'll meet the menu bar, Dock, Control Center, and even the Trash. • The Finder: What is the Finder, and what can it do? Explore windows, your desktop, Quick Look, the Go menu, and other elements of your Mac's file management app. • What's on disk: Find out where files and folders are located, and how to navigate your Mac without getting lost. • Your Apple Account and iCloud: Your Mac becomes vastly more powerful when you connect it to Apple's online services. • Apps: The book describes every single app included with your Mac and explains the basics of working with apps, including where and how to obtain new ones. • Systemwide features: Get to know features that work everywhere on your Mac, such as Siri, Spotlight, your clipboard, notifications, and screenshots. • Customization: Find your way around System Settings and set up your Mac to work just the way you like it. • Safety and privacy: Make sure your Mac's data is safely backed up, and keep your private information away from people who shouldn't see it. • Switching from Windows: If you're switching from Windows to Mac, you'll learn about the important similarities and differences, and how to accomplish common tasks "the Mac way." Note: This book is for Macs running macOS 13 Ventura or later, including macOS 14 Sonoma and macOS 15 Sequoia. Most Macs released since 2017 support one or more of these versions, and upgrade instructions are included in the book for those still running macOS 12 Monterey or earlier.

Leverage your smartphone and smartwatch for improved personal safety! Version 1.1, updated November 26, 2024 The digital and “real” worlds can both be scary places. The smartphone (and often smartwatch) you already carry with you can help reduce risks, deter theft, and mitigate violence. This book teaches you to secure your hardware, block abuse, automatically call emergency services, connect with others to ensure you arrive where and when you intended, detect stalking by compact trackers, and keep your ecosystem accounts from Apple, Google, and Microsoft secure.n You don’t have to be reminded of the virtual and physical risks you face every day. Some of us are targeted more than others. Modern digital features built into mobile operating systems (and some computer operating systems) can help reduce our anxiety by putting more power in our hands to deter, deflect, block, and respond to abuse, threats, and emergencies. Keep Safe Using Mobile Tech looks at both digital threats, like online abuse and account hijacking, and ones in the physical world, like being stalked through Bluetooth trackers, facing domestic violence, or being in a car crash. The book principally covers the iPhone, Apple Watch, and Android devices, but doesn’t ignore Wear OS watches, the iPad, and computers running macOS or Windows. This book explores many techniques to help: • Learn how to harden your Apple ID/Apple Account, Google Account, and Microsoft Account beyond just a password or a text-message token. • Discover blocking tools in operating systems and third-party apps that can prevent abusive, fraudulent, and phishing messages and calls from reaching you. • Block seeing unwanted sensitive images on your iPhone, iPad, Mac, or Apple Watch—and help your kids receive advice on how not to send them. • Turn on tracking on your devices, and use it to recover or erase stolen hardware. • Keep your cloud-archived messages from leaking to attackers. • Lock down your devices to keep thieves and other personal invaders from accessing them. • Prepare for emergencies by setting up medical information on your mobile devices. • Let a supported smartphone or smartwatch recognize when you’re in a car crash or have taken a hard fall and call emergency services for you (and text your emergency contacts) if you can’t respond. • Keep track of heart anomalies through smartwatch alerts and tests. • Tell others where or when you expect to check in with them again, and let your smartphone alert them if you don’t. • Deter stalking from tiny Bluetooth trackers. • Protect your devices and accounts against access from domestic assailants. • Block thieves who steal your phone—potentially threatening you or attacking you in person—from gaining access to the rest of your digital life.

Share screens and files among your Apple devices and beyond Version 1.0, published February 26, 2025 Do you need to access a Mac across the room—or around the globe? Or share files securely with a relative or colleague? Want to know about Apple’s latest, much-improved screen sharing among iPhones, iPads, and Macs, and what’s missing in them? This book is a friendly but comprehensive guide to screen sharing, screen mirroring, network file sharing, and cloud file sharing using Apple devices.n The software and data we need is often not right in front of us. Take Control of Apple Screen and File Sharing provides a fully up-to-date guide to the many resources for accessing stuff we don’t have within reach. You learn how to access your own screens nearby, over a network, and over the internet, share your screens with others for remote control or viewing, and mirror screens to larger displays and into group chats. You also become an expert on local file sharing with Macs and sharing from cloud-based storage, like iCloud Drive and Google Drive. With the help of this book, you’ll: • Get to know the Mac Screen Sharing app to connect to view and control the screens of other Macs. • Access other people’s screens to help them troubleshoot problems or share what they’re working on, for work or fun. • Understand where third-party screen-sharing systems improve on Apple’s offerings. • Learn the difference between screen sharing and mirroring, and where the two intersect—and even overlap. • Use screen sharing over FaceTime and Messages with one person or dozens (using Macs, iPhones, or iPads). • Mirror your iPhone's screen (and, optionally, its notifications) on your Mac. • Find out how and why mirroring an Apple Watch to an iPhone could be useful. • Set up and use networked file sharing on your Mac. • Turn to cloud services like iCloud Drive, Dropbox, Google Drive, and Microsoft OneDrive to share files securely with others and impose limits on what they can do. • Enable secure remote access among all your devices—and with other people—using a virtual local area networking (VLAN) system. • Get to understand Virtual Network Computing (VNC) screen sharing—its standardization, its limitations, and its security weaknesses.

Master networking, privacy, and security for iOS and iPadOS! Version 4.2, updated January 29, 2024 Ensuring that your iPhone or iPad’s data remains secure and in your control and that your private data remains private isn’t a battle—if you know what boxes to check and how to configure iOS and iPadOS to your advantage. Take Control of iOS & iPadOS Privacy and Security takes you into the intricacies of Apple’s choices when it comes to networking, data sharing, and encryption—and protecting your personal safety. Substantially updated to cover dozens of changes and new features in iOS 17 and iPadOS 17! Your iPhone and iPad have become the center of your digital identity, and it’s easy to lose track of all the ways in which Apple and other parties access your data legitimately—or without your full knowledge and consent. While Apple nearly always errs on the side of disclosure and permission, many other firms don’t. This book comprehensively explains how to configure iOS 17, iPadOS 17, and iCloud-based services to best protect your privacy with messaging, email, browsing, and much more. The book also shows you how to ensure your devices and data are secure from intrusion from attackers of all types. You’ll get practical strategies and configuration advice to protect yourself against psychological and physical threats, including restrictions on your freedom and safety. For instance, you can now screen images that may contain nude images, while Apple has further enhanced Lockdown Mode to block potential attacks by governments, including your own. Take Control of iOS & iPadOS Privacy and Security covers how to configure the hundreds of privacy and data sharing settings Apple offers in iOS and iPadOS, and which it mediates for third-party apps. Safari now has umpteen different strategies built in by Apple to protect your web surfing habits, personal data, and identity, and new features in Safari, Mail, and Messages that block tracking of your movement across sites, actions on ads, and even when you open and view an email message. In addition to privacy and security, this book also teaches you everything you need to know about networking, whether you’re using 3G, 4G LTE, or 5G cellular, Wi-Fi or Bluetooth, or combinations of all of them; as well as about AirDrop, AirPlay, Airplane Mode, Personal Hotspot, and tethering. You’ll learn how to: • Twiddle 5G settings to ensure the best network speeds on your iPhone or iPad. • Master the options for a Personal Hotspot for yourself and in a Family Sharing group. • Set up a device securely from the moment you power up a new or newly restored iPhone or iPad. • Manage Apple’s built-in second factor verification code generator for extra-secure website and app logins. • Create groups of passwords and passkeys you can share securely with other iPhone, iPad, and Mac users. • Decide whether Advanced Data Protection in iCloud, an enhanced encryption option that makes nearly all your iCloud data impossible for even Apple to view, makes sense for you. • Use passkeys, a high-security but easy-to-use website login system with industry-wide support. • Block unknown (and unwanted) callers, iMessage senders, and phone calls, now including FaceTime. • Protect your email by using Hide My Email, a iCloud+ tool to generate an address Apple manages and relays messages through for you—now including email used with Apple Pay transactions. • Use Safari’s blocking techniques and how to review websites’ attempts to track you, including the latest improvements in iOS 17 and iPadOS 17. • Use Communication Safety, a way to alert your children about sensitive images—but now also a tool to keep unsolicited and unwanted images of private parts from appearing on your devices. • Understand why Apple might ask for your iPhone, iPad, or Mac password when you log in on a new device using two-factor authentication. • Keep yourself safe when en route to a destination by creating a Check In partner who will be alerted if you don’t reach your intended end point or don’t respond within a period of time. • Dig into Private Browsing’s several new features in iOS 17/iPadOS 17, designed to let you leave no trace of your identity or actions behind, while protecting your iPhone or iPad from prying eyes, too. • Manage data usage across two phone SIMs (or eSIMS) at home and while traveling. • Use a hardware encryption key to strongly protect your Apple ID account. • Share a Wi-Fi password with nearby contacts and via a QR Code. • Differentiate between encrypted data sessions and end-to-end encryption. • Stream music and video to other devices with AirPlay 2. • Use iCloud+’s Private Relay, a privacy-protecting browsing service that keeps your habits and locations from prying marketing eyes. • Deter brute-force cracking by relying on an Accessories timeout for devices physically being plugged in that use USB and other standards. • Configure Bluetooth devices. • Enjoy enhanced AirDrop options that let you tap two iPhones to transfer files and continue file transfers over the internet when you move out of range. • Protect Apple ID account and iCloud data from unwanted access at a regular level and via the new Safety Check, designed to let you review or sever digital connections with people you know who may wish you harm.

Overcome password frustration with Joe Kissell's expert advice! Version 4.2, updated January 9, 2025 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: • Short 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.
