macOS 26 Tahoe, which made a huge version number leap from macOS 15 Sequoia, joins other Apple operating systems in using a new year-based numbering scheme. Featuring Liquid Glass, the first major user interface overhaul in years, plus a great many new features, Tahoe makes your Mac more powerful than ever. This book thoroughly covers everything that’s new or different, and provides detailed upgrade instructions. (It isn’t a complete guide to everything Tahoe can do. To get a full overview of your Mac’s features, read Mac Basics.)

Buy a bundle and save! If you buy this book plus Take Control of iOS 26 and iPadOS 26 at the same time, you can save 25% (pay $14.99 versus the combined cover price of $19.98). To buy the bundle, click this link or add both books to your cart and enter coupon code YNAZHYWV at checkout.

This book teaches you things like:

  • How to tell whether your Mac is compatible with Tahoe (and which features require an M-series Mac)
  • Steps you should take before upgrading
  • How to upgrade your Mac to Tahoe using either an in-place upgrade or a clean install (including migration of your old data from a backup)
  • How Liquid Glass changes the appearance of macOS, the many ways you customize it, and how to disable parts of the new interface you may dislike
  • Brand-new ways to customize Control Center and your menu bar
  • What’s new in Spotlight: a completely revamped interface and support for Actions that let you perform hundreds of activities from the keyboard without opening a single app
  • Using the new Phone app for Mac, which includes features like Hold Assist, Call Filtering, and Call Screening
  • How to carry on a conversation with someone who speaks another language using the Live Translation feature in FaceTime, Messages, and Phone
  • New Mac apps: Apps (yes, an app called “Apps”!), Games, Journal, and Magnifier
  • What’s new in the System Settings app
  • The but interesting changes you’ll find throughout macOS, such as accessibility improvements and new capabilities for AirPods, AutoFill, Family, Genmoji, and more
  • Noteworthy improvements to bundled apps, including FaceTime, Image Playground, Messages, Music, Passwords, Photos, Reminders, Safari, and Shortcuts

What’s New in Version 1.2

Version 1.2 of this book reflects changes in macOS Tahoe 26.1, released in early November 2025. The most significant modifications were:

  • Liquid Glass display option: Added information on additional ways to change the appearance of Liquid Glass. See “Reduce Liquid Glass Effects.”
  • Spotlight clipboard history controls: Described new controls for Spotlight’s clipboard history. See “Use Clipboard History.”
  • Communication safety change: Added a paragraph about a change to communication safety for Family Sharing members aged 13–17. See “Family.”
  • Recovery Assistant links: Updated “Recovery Assistant” with links that provide a bit more information.
  • More details on Shortcuts improvements: Added information about previously unmentioned improvements to Shortcuts. See “Shortcuts.”

What Was New in Version 1.1.1

Since version 1.1 of this book was wrapped up just before Tahoe’s official release on September 15, I discovered only after the new version of macOS shipped that Apple decided to change the way the installer was offered for the first time in many years. The Tahoe installer is not available in the Mac App Store. Nor has Apple has provided any indication as to whether it will appear there later. As a result, I revised instructions in “Make Final Preparations”—particularly “Obtain the Installer” and “Copy the Installer to a Safe Place.”

I also added a bullet point in “Privacy & Security Settings” to cover some changes in FileVault.

What’s New in Version 1.1

Version 1.1 of this book addresses a few small changes between the beta version of Tahoe available when version 1.0 was published and the release version of Tahoe 26.0, as well as mentioning one or two new items I didn’t catch the first time around:

  • Removed the now-obsolete references to the Tahoe beta.
  • Added a clarification about display contrast in “Reduce Liquid Glass Effects.”
  • Added a “Battery Settings” topic that covers the new High Power option for Mac laptops.
  • Removed the “Notifications Settings” topic, which only pointed out a missing feature that returned during the beta cycle.
  • Added “Keyboard Settings,” with instructions to suppress a potentially annoying Apple Intelligence feature.
  • Completely reworked the Live Translation instructions, which were previously missing crucial steps.
  • In “Music,” included instructions for toggling AutoMix in a playlist.
