I really would like to have a basic book to use in learning to use my new MacBook Air with El Capitan. I know there are YouTube tutorials and such, but I like to have a book laying open to reference. Was hoping some of you would have some suggestions. Doing a little searching on line I have identified perhaps three basic types. First, there are several I have seen that are dedicated to people switching from the PC to the Mac. I doubt that would be helpful because I get the impression that the writer may be assuming I know a lot more about the PC than I actually do. Second, there are book that seem to be dedicated to Macs in general. And third, there seem to be books dedicated to a specific Mac operating system. I have no idea which of these would be the best, but am eager to explore options. And please don't feel shy about recommending a specific book and/or a specific author. Thanks!
