Hidden User Library folder after Lion 10.7 upgrade21st Jul 2011
If you’ve lost the Library folder from your User’s home folder after an upgrade to the new OS X 10.7 Lion, open Terminal (Applications > Utilities folder) and type the following command :
chflags nohidden ~/Library
Push return and your Library folder will return once more!
*edit* post corrected “no hidden” to “nohidden”, no thanks to Lion’s new autocorrect feature!
