The book comprehensively covers networking, privacy, and security in iOS 14 and iPadOS 14 (including version 14.5), answering any question you might have across all of those areas. The book covers Wi-Fi, Bluetooth, and cellular networking; third-party password managers; using Find My for tracking your devices and AirTags tracking an iOS device; USB port blocking to prevent brute-force passcode cracking; Low Data Mode for cellular and Wi-Fi data; using the Apple Watch on a Wi-Fi network; configuring and setting up Personal Hotspot and Instant Hotspot; blocking jerks and spam; two-factor authentication with an Apple ID; using AirDrop and AirPlay; solving connection problems; and much more.
The book offers insight into what information you may unintentionally expose about yourself, and how to prevent Apple and third parties from gaining access to your details. This includes the several techniques Apple has built into Safari for iOS and iPadOS that prevent advertising and tracking companies from following your actions and connecting your browsing behavior on unrelated sites.

What’s New in Version 1.3
Apple made a few small but significant changes related to AirTags on May 24, 2022, in iOS/iPadOS 14.6 and to the webpages associated with AirTag serial numbers:
- Apple now lets you provide either a phone number or an email address when you mark an AirTag as lost.
- On June 3, 2021, Apple reduced the time before an AirTag starts making a noise after being separated from its owner.
- Apple also said they would release an Android app for monitoring the presence of AirTags traveling with someone later in 2021.
- When someone finds an AirTag, reads it via an NFC device, and follows the embedded link to a page associated with its embedded serial number, Apple now displays the last four digits of the phone number associated with the Apple ID account with which the AirTag is registered (via an iPhone or iPad).
I’ve updated “Find Your Devices” throughout to reflect those changes.
What Was New in Version 1.2
Apple’s new AirTag location trackers alert people about their presence when the owner isn’t in the vicinity for a period of time. But the details about when and how are somewhat complicated, including when the trackers are ostensibly misused to stalk someone or otherwise track them without their knowledge or consent. In version 1.1, my explanation left out a few bits and pieces and wasn’t as clear as it could be.
I’ve added more detail throughout “Find Your Devices,” particularly explaining how unwanted or unknown tracking interactions can be managed by someone near an AirTag.
What Was New in Version 1.1
Apple imposed new requirements for disclosing the data an app collects in December 2020, and how it uses it and for obtaining tracking permission across apps and websites April 26, 2021. These changes were described in version 1.0 of the book, but couldn’t be shown precisely until they were rolled out. See “App Privacy Controls Improve.”
Since the previous version, Apple also made some significant changes and expansions to its Find My system for tracking lost and stolen items:
- First, they opened allowed third parties to tie into the Find My network (see “Discover Disconnected Devices”), which relies on privacy-protecting detection of lost items by other people’s iPhones, iPads, and Macs; products are in the pipeline for later in 2021.
- Second, they renamed and changed parts of the Find My configuration and in the Find My apps, including adding a new tab to the native apps in iOS, iPadOS, and macOS. See “Enable Find My.”
- Third, Apple shipped the AirTag, a compact device that pairs with an iPhone or iPad, and then can be found through the anonymous, secure crowdsourcing part of Find My. See “Track via an AirTag or Accessory.”
This required substantial revisions and additions to the chapter now called “Find Your Devices”; you’ll find up-to-date information there on all the changes.
Apple slipstreamed in a major change to AirPlay in iOS 14.2/iPadOS 14.2 that led me to update, rethink, and expand the “Stream via AirPlay” chapter. This chapter now separates out audio, video, and screen mirroring, includes details about HomePods, and explains how the media players tiles accessible via Control Center work.
Apple and Google’s COVID-19 privacy-preserving exposure notification system released in 2020 was expected to provide some help in tracking contacts without disclosing any information. However, due to late adoption and non-adoption by health agencies, and a low uptake in areas that did support it, the system was seemingly ineffective in improving people’s self-quarantine after potential exposure. I’ve removed that chapter entirely for now, as it is no longer relevant.
This version also updates the book to account for the release of true 5G cellular networking in iPhone models, some changes in cellular providers’ service plans, and updates around the flavors and speeds of 5G available. You can find all that in “Manage Cell Data Usage.”
Some minor typos are also fixed in this version.
