In Mac OS X 10.7 (Lion), the Library folder in your home folder is now hidden. There are a couple of ways gain access to it.
To quickly browse your Library folder, open a Finder window and click the Go menu. Then press and hold Option . You’ll see a new entry temporarily appear for the Library folder, which will disappear when you release Option .
To permanently restoring access , open a Terminal window and type the following:
chflags nohidden ~/Library/ Now when you visit your home folder, the Library folder should be visible.
Note that you’ll likely have to repeat the chflags command each time you install a major system update for OS X
