By default Finder in OSX hides a lot of files from the user. This is useful if you are a standard user but when you need access to /usr, /var or /Library this is really annoying. To enable finder to show all enter the following command into terminal.

defaults write com.apple.finder AppleShowAllFiles TRUE

You will then either need to logout your profile or run the command:

sudo killall Finder
