I know most of you probably don’t have the dev release of Mac OS X 10.7 Lion, but I got it today, and a really big thing was changed… Apple hide the Library folder which is usually in your Home folder. After a little bit of searching, I found the answer on how to unhide it.
1)

Click “Search” + write “Terminal” and click “Terminal”
2)
Write “chflags nohidden ~/Library/” and click “Enter”
Done….
