Oct 03, 2018  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. May 17, 2019  Within the Library folder are a lot of pretty critical files that apps on your Mac need to operate. Since Mac OS X Lion and Mountain Lion, the Library folder has been hidden, to avoid people accidentally deleting critical folders and applications.

Prior to Mac OS X Lion's release back in 2011, if you wanted to access the Library folder you could just open your Home folder and view the Library folder there. That folder is still located in. You can access the Library folder with the Go To Folder command or from the Terminal app. Access the Library folder in Finder: In Finder, choose Go Go To Folder In the Go To The Folder field, enter /library/. Sep 27, 2016 Open Finder, or just click on the desktop. Then click “Go” in the menu bar, and select “Go to Folder”. You can also skip all this clicking by pressing Command+Shift+G on your keyboard to access the Go to Folder menu. Type /Library in the box and hit Enter.

  1. Turn on or restart your Mac, then immediately press and hold Command (⌘)-R to start up from macOS Recovery.
  2. You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.
  3. When you see the macOS Utilities window, choose Utilities > Terminal from the menu bar.
  4. Type repairHomePermissions in the Terminal window, then press Return. The Repair Home app opens.
  5. Select your user account, click Next, then enter your administrator password. Click Next unlock the volume and begin resetting permissions on your home directory.
  6. When done, click Exit to return to the macOS Utilities window.
  7. Select Reinstall macOS, then click Continue and follow the onscreen instructions to reinstall macOS.

If resetting permissions doesn't resolve the issue:

  1. Make sure that you have a backup of your Mac, then erase your startup disk.
  2. When done, reinstall macOS.
  3. After installation completes and your Mac restarts to the setup assistant, create a new user account using a different name than the one you were using before. Any difference in spelling is enough.
  4. If you made a Time Machine backup, use Migration Assistant to restore all your files from the backup.

Learn how to access the hidden Library folder in your Home folder on your Mac so you can tweak app settings and access app files.

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.

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.
