From my perspective, there is a very minor learning curve switching between MSWindows and MACOS. The two are very, very similar to an end user. I run into people who, as soon as you mention Linux (as in what the Pi runs) get all nervous and fearful. I point out that, if you can use *either* Windows or Mac, then Linux should look familiar and using the Linux GUI should be really rather familiar.
Fundamentally, a GUI (or, as it used to be called, WIMP) interface is pretty much the same no matter what the underlying OS is. All you have to do is experiment a bit to find out what minor differences and peculiarities (compared to others) it has. It is a *good* thing to learn how to use more than one GUI/OS because then you will start to understand the underlying principles and not get hung up on the differences. (The same general advice applies to programming languages...with your first language, you are learning to program as well as the specific language. With the second, and subsequent languages, you are learning more general principles of programming, plus that new language.)
