You will need a Mac with macOS installed—the latest version, if possible, which, at the time of publication of this book, is macOS Big Sur. There may be differences in the UI according to the Mac machine model you are using, whether you are using a Mac with the Apple M1 silicon chip, with the T2 chip, an iMac, and so on, and we have tried to point out those differences in most of the examples. However, it is not always possible to do so every time, or the differences are not significant.
Since this is not a Mac or a macOS user guide, it would be very helpful to be familiar with the Mac hardware and the macOS environment. If you are new to the world of Mac and macOS, it might be helpful first to check out a Getting Started guide. There are many good examples available on the internet that will walk you through the basics of using a Mac for the first time.
