A quick note on installing Spark on other operating systems: the same steps will basically apply on them too. The main difference is going to be in how you set environment variables on your system, in such a way that they will automatically be applied whenever you log in. That's going to vary from OS to OS. macOS does it differently from various flavors of Linux, so you're going to have to be at least a little bit familiar with using a Unix terminal command prompt, and how to manipulate your environment to do that. But most macOS or Linux users who are doing development already have those fundamentals under their belt. And of course, you're not going to need winutils.exe if you're not on Windows. So, those are the main differences for installing on different OSes.
