Inside the home folder on your Mac is a Library folder that stores app-specific files and settings, personal settings, and some data. The files and settings in the Library folder should be left alone for the most part. But, you may want to tweak the settings for an app, which may require accessing the Library folder. Or, maybe an app backs up data to the Library folder and you want to copy that to an external drive.

Before going ahead with the steps to Access the Hidden Library Folder on your Mac, you need to be aware that /Library Folder contains important Data and Files related to Mac User Accounts. Hence, make sure that you are accessing the Library Folder for a good reason and you do know as to what you are trying to achieve.

As of Mac OS X Lion (10.7), the Library folder in your home folder is hidden by default. That doesn’t mean you can’t get to it. It’s hidden so you don’t accidentally delete settings and data, damaging apps in the process. So, if you decide you want to access the Library folder, be very careful.

Today we’re going to cover different ways of accessing the hidden Library folder in your home folder and how to make it permanently available in Finder.

What is the Path to the Library Folder?

The Library in your home folder is written as ~/Library. The tilde (~) character is a shortcut for your home directory. For example, on my Mac, that would expand to /Users/lorikaufman/Library.

Access the Library Folder Using the Go to Folder Option

If you want to access the Library folder only occasionally, you can use the Go to Folder option in Finder.

Open Finder or just click on the desktop. Head to Go > Go to Folder, or hit Cmd + Shift + G.

Type:~/Library in the Go to the folder box on the dialog box and click Go or press Enter.

If you have one or more Finder windows open, the Library folder opens in the currently active window. If no Finder windows are open, a new one opens to the Library folder.

Access the Library Folder Using the Terminal

If you prefer using the command line, you can access the Library folder using the Terminal.

Go to Utilities > Terminal in the Applications folder. To access the Library folder directly in the Terminal, type:cd ~/Library at the prompt to switch to the Library folder.

You can type:ls at the prompt to get a detailed folder listing. You can work with the files in the Library folder directly on the command line. Just be careful.

You can also use the Terminal to open the Library folder in a Finder window. Type:open ~/Library at the prompt and hit Enter.

Access the Hidden Library Menu Option in Finder

The Library folder is available on the Go menu in Finder, but it doesn’t show on the menu by default.

To temporarily show the Library option on the Go menu, open the menu and press the Option key. The Library folder shows up between Home and Computer on the Go menu. Keep the Option key pressed while you move your mouse down the menu and select Library.

If you’re using a Windows keyboard with your Mac, press the Alt key.

Show the Library Folder Permanently in Finder

If you access the Library folder often, you can permanently show the Library option on the Go menu and the Library folder in your Home folder.

Open Finder and head to your Home folder using the left pane or by pressing Cmd + Shift + H. Then, go to View > Show View Options, or hit Cmd + J.

A dialog box displays with options you can set for your Home folder. Check the Show Library Folder box at the bottom of the dialog box. The Library folder now shows up in your Home folder in Finder windows and the Library option becomes permanently available on the Go menu.

When you permanently show the Library folder in Finder, you can hit Cmd + Shift + L to open it in a Finder window, in addition to selecting the Library option on the Go menu.

Happy Tweaking, But Be Careful

The Library folder is hidden by default for a good reason. So, before tweaking settings and changing files in the Library folder, make sure you know what you’re doing.

  • The files and file locations given here are defaults. Some of these locations can be customized in the Lightroom Preferences or Catalog Settings dialog boxes.
  • While troubleshooting, when possible, rename files instead of deleting them.
  • If possible, back up catalogs on a different hard disk or volume from the disk where your catalog is located. For more information on backing up in Lightroom Classic, read Back up a catalog.

Note: The user Library file is hidden by default on Mac OS X 10.7 and later. For temporary access to the user Library file, press Option and choose Go > Library in the Finder.
