I just switched from windows to macbook pro this past week and stumbled around a bit trying t figure out how use the mac. I ended up going to the local bookstore and bought a book titled "Switching to the Mac, the missing manual" by David Pogue. It retailed for $29.99 and is ending up being worth every penny for me. The only point of difference, is this book is written for the Yosemite OS X and I just upgraded to El Capitan. My understanding is that the principles of using the OS are the same in Yosemite and El Capitan, which is what I am after - just how to lean the Mac. Later on, I can get a book on the El Capitan OS, if I need it. Amazon has this book for $21 and you can preorder the El Capitan version for $19.95. Hope this helps.
