Access User Library Folder in OS X Lion
Configuring Tunnelblick often requires access to the Tunnelblick Configurations folder located in the user's Library folder under 'Applications Support'.
OSX Lion, unlike previous versions of OSX, hides this folder by default. You can un-hide the folder and make it work like previous versions of OSX as shown below:
--Open 'Terminal' from the Utilities menu
--Enter the following command:
chflags nohidden ~/Library/
--Hit enter to un-hide the folder
--Close out 'Terminal' and proceed as you would with earlier versions of OSX
