How to Open the Library Folders on Your Mac

The Library folder on your Mac contains system files and settings, which are essentially divided into three: System, User, and Local. While the System and Local Library folders are always accessible, by default the User Library folder is hidden to avoid accidental deletion of important files. Here's how you can enable all three Library folders on your macOS device.

Opening the Library Folder on Your Local Mac

The Local Library folder is a system-level directory at the root of your Mac's hard drive. It is, in fact, a shared folder between all user accounts on the system. The folder holds important system-wide settings and files that include the likes of screensavers, wallpapers, and application preferences.

Note: Apple does not advise you to keep your folders and personal files inside the Local Library. After all, the system might become unstable or act weird if you have modified something in this directory.

Opening a Local Library folder: First, open Finder, and then on your Mac, go to Macintosh HD. It is right under the root directory. Double click on the folder Library to open its contents.

Note: Although this folder is accessible, in general, it's best not to change the contents of the Local Library folder at all unless you know why you need to, and you know what your actions may have as a result.

How to Open the User Library Folder on Your Mac

The User Library folder is a folder unique to each user account on your Mac. It houses personal data, settings, and supporting files for various apps. By default, it is hidden, but one can easily get access through some simple steps.

To Show User Library Folder:

Menu Bar: On the menu bar, click "Go" and holding the key "Option" click on "Library."

Finder Shortcut: Open up Finder, then click on your Home folder, and press Command + Shift + Period.

To Always Show the User Library Folder:

Finder Settings: In the Finder, navigate to your Home folder and then click on "View" > "Show View Options."

Check Box: In the popup window, check the box titled "Show Library Folder.".

Direct Access: The folder can also be accessed more quickly using "Go" > "Go to Folder" and typing "~Library" in the dialog box.

Important Note: The User Library folder is very useful for understanding many aspects of your system's behavior and personal preference; however, changing the files in it may introduce unexpected problems if done carelessly. Be very careful when you do, and it is a good idea to back up your system before you start playing around with Library files.

Opening System Library Folder on a Mac

The System Library folder is an integral part of the system that holds some of the important files and settings that enable the proper functioning of the macOS. It has System Integrity Protection, which protects it against modifications that aren't authenticated; therefore, one cannot edit or delete any content in the folder. Only system-level events, like updates or repairs, may affect the files contained therein.

To access the System Library folder:

Finder: Open Finder, then select your Mac's internal drive (Macintosh HD), and then select "System" > "Library."

Direct Access: Select "Go" > "Go to Folder" and then type "/System/Library."

Important Note: Modifying the System Library folder can have really serious implications, so while you may want to investigate the User Library folder to free up space by deleting files you no longer need, such as cache or log files, that is a different story.

Be careful not to delete or change any files unless you know what you're doing and are properly trained. Leave the System Library folder alone unless you are very sure of what you're doing.
