By default on Mac computers with MacOS Sierra, Capitan, or Yosemite, the Library folder is usually hidden as a security measure. This folder usually contains preference files, caches and support data of the applications installed on your Mac. This content is sensitive since if it is removed improperly, we can make our programs not work correctly. This is precisely why by default the Library folder is hidden by default on Mac.

However, there are many users, especially the most advanced, who prefer that this folder be shown in their MacOS operating system.

Once you open the user box and it is displayed in the Finder, you must click on the Display option located in the upper bar of the screen. This will bring up a menu where you will have to click on the Show display options option . By clicking on this option you will see how a new window opens in which you can see various configuration options. In our case we should look for the one that says: Show Library folder.
Once the box shown next to said option is checked, you can close this window and check how the Library folder will be shown in the user folder. From this time you can access the Library folder simply by using the keyboard shortcut: Shift + CMD (command) + L ..
Another way to access the libraries will be by using the Go Menu located in the upper bar of your Mac's screen. Clicking on the Go option will display a menu where the Library option will now be displayed in which you will have to click to access it directly.
