Summary: Here in this blog, you will get to know where the Library folder on Mac is, how to reveal it and how to clean it when it's huge. 

To avoid damage caused by accidentally deleting important files in the Library folder, Apple hides the Library Folder in macOS 10.7 and later.

If you don't know it very well, read on this blog to learn where it is, how to open it, and how to clean it when it takes up a lot of storage space.

Mac Library Folder Huge? Here's How to Clean It Up

What Is the Library Folder on Mac?

Before understanding what the Library folder is, let's take at how many library folders there are on your Mac.

There are several library folders on your Mac. The most common ones are located in the following paths:

  • /Library
  • /System/Library
  • /Users/Your Name/Library
macOS Folder Layout

/Library refers to the library folder under the root directory, which contains shared resources for all users. (Apps that share resources between users store those resources in this directory.)

/System/Library refers to the system library, which is a system-specific folder.

/Users/Your Name/Library, also written as ~/Library, is the library folder used by the current user and not accessible by other users.

We often refer to the user library folder as Library Folder.

Can I Delete the Library Folder on Mac?

No, you're not allowed to delete the library folders on your Mac.

The files in /System/Library and /Library keep your macOS and applications running properly, and we strongly recommend that you leave them untouched. However, some files in /Users/Your Name/Library (~/Library) can be deleted, such as caches, logs, crash reports, etc.

How to Open the Library Folder on Mac

As we mentioned earlier, Apple hides the Library folder. However, sometimes we need to access it to fix some issues with your apps.

Here's how to reveal it on your Mac:

Open It Temporarily:

Method 1:

Click the Go menu in Finder, press the Option key, and you'll find the Library option.

Method 2:

Click the Go menu in Finder and choose Go to Folder, paste ~/Library into the search box, and press the Return key. (Also, you can use Shift-Command-G keys to open the Go to Folder window.)

Reveal It Permanently:

Open Terminal, paste the command: chflags nohidden ~/Library && xattr -d ~/Library, and press Return.

(Run the command: chflags hidden ~/Library && xattr -wx "0000000000000000400400000000000000000000000000000000000000000000" ~/Library to hide the user library folder.)

You can press Command + Shift + . (period) to show all hidden files on your Mac.

What To Do When the Library Folder Is Huge on Mac

You may notice that your Library folder is taking up a lot of space. This won't be a problem if you have enough storage space. However, if you're running low on storage, clearing it will help you free up some valuable space.

You can manually clear this folder using the Finder, but it will take a lot of your time. Here, we introduce you to a faster way, which is to use BuhoCleaner one of the best Mac cleaners. With its disk space analyzer, you can visually manage the folders and files in the Library folder.
