Macs don't come with a printed manual, because help is built right in!
It's easy to overlook, but the Help menu can help you find just about any answer to your questions. It's built in to Finder in your Mac, and it's present in most applications too. Apple's contextual Help menu is like having an interactive manual built right into the Finder and the applications you use. It isn't just for newbies, either—even experienced Mac users can benefit.
Help Center is absolutely one of the most underutilized resources in the operating system. I see so many questions posted to Internet forums and social media on a daily basis that can be answered through Help Center: It should definitely be your first line of defense if you run into problems or don't understand how to use a feature of an application.
The important thing to understand is that the Help menu is contextual: The contents will change depending on which application you have open. Looking at the Help menu from the Finder, for example, reveals three options: A search field, Mac Help, and "Get to know your Mac." Inside a third-party application, you may find links to a manual, shortcut references, links to help forums on the developer's web site, and other content.
That search field can also be used to find any menu command in your application of choice: If you're looking for "Add Bookmark" in Safari, for instance, you can just type in "Add B" and Safari will find the menu command for you. I use this all the time to find commands rather than search through submenu after submenu for them.
So make sure to use this important resource and explore what you find!
