Since Mac OS X 10.7 (Lion), the user Library folder (Mac HD/Users/YOUR_USERNAME/Library) is hidden by default.
How to access the User Library temporarily
- Select a Finder window or click on your Desktop
- Select Go from the top menu bar
- Hold down the Alt/Option key on your keyboard
- Library will now show up in the menu, click on it to open your user Library folder.
Tip: Permanently show hidden files
If you find yourself accessing the User Library folder often, you can also make it visible in Finder permanently. (And reversibly.)
On current macOS versions
- Open a Finder window and press shift + ⌘ + ..
On macOS 10.14 Mojave
- Open a Finder window, check that your user home folder (house icon) is listed in the sidebar on the left
- If your user home folder is not listed there:
- Go into Finder’s Preferences (⌘ + , on keyboard)
- Switch to the Sidebar page at the top of the preferences dialog
- Tick the checkbox next to your user home folder
- Close the preferences dialog and return to the Finder window
- If your user home folder is (now) listed in the Sidebar, left-click it to navigate your Finder window there
- Hover your mouse over an empty background area of the file/folder listing window inside your user home folder
- Right-click the empty background area and select Show View Options from the dropdown menu
- In the now displaying dialog, tick the checkbox Show Library Folder near the bottom
You should now see the Library folder inside your user home folder.
To hide the User Library folder again, follow above steps once more, but un-tick the Show Library Folder checkbox in the last step.
On macOS 10.13 High Sierra or earlier
Launch Terminal, then enter the following command:
chflags nohidden ~/Library
To hide the user library again, launch Terminal, then enter the following command:
