If you think that Apple should simplify everything (like this coil), I would say that let there be confusion or complexity. Because Apple wants you to stay away from this so that you can smoothly operate the Mac. Apple keeps some files as hidden in its Mac OS X so that nobody can tamper with those important data stored in the hidden files. As a matter of fact, this “secret treasure” should not be located by any intruder (read new user.) As a Mac owner, if you want to show those hidden files in Mac OS X, here is a method. Mac Terminal is one of the most popular apps used and eulogized by experts. This app allows you to control Mac OS X by using the command line to enter Unix commands. In a way, Terminal works as car bonnet, which you can open and check entire engine. The app helps you open Mac OS X and take a look what is happening there. Here is how to use Mac Terminal.

Click on the Terminal app. Or You can search for terminal from spotlight search. Step #4.
