macOS Big Sur for Users, Administrators, and Developers covers the new features with the latest release. macOS Big Sur brings a slew of new features like new icons, a refined design with updated toolbars, menu, and alerts. The new design is accompanied by Messages and Maps now having feature parity with their iOS versions, which means new features coming to the Mac that were not present before. One of the most used apps on the Mac is Safari, and there is a whole new privacy section to help you see which websites are tracking you and which trackers they are using. Reminders and Notes have seen a couple of updates like assigning reminders and easier access to text styles in notes. The biggest change for the Mac this year is that it is moving to Apple Silicon and a significant portion of the book is dedicated to that, including a history of the Mac.

For administrators we dive into managing Macs running Apple Silicon, scripting language updates, some changes to how updates are handled, and the updates to Profile Manager.

Developers can learn about how Apple Silicon will affect their applications, the changes to Xcode, enhancements to the Swift programming language and SwiftUI. Also discussed are some new Swift Packages, how to implement Widgets using WidgetKit, SF Symbols 2, and Safari extensions.

macOS Big Sur for Users, Administrators, and Developers has something for everyone.
