Lion has changed the way the Finder handles file/folder visibility. The most noticeable difference is that, by default, ~/Library/, is hidden. This is probably a good decision for most users, as it can be confusing and I have seen users stash their documents in there. I think they could have gone further, /Library/ and /System/ ought to be hidden too. But this can be pretty annoying if you're a power user who wants access to ~/Library/ (if you're reading this, then this probably means you). Luckily, you can change a folder/file's visibility with a simple Applescript: Code: tell application "System Events" set visible of folder "~/Library/" to true end tell If you want to re-hide the folder, just change true to false and re-run. I should also note that Lion changes another way in which the Finder handles visibility: you can no longer add a period to start of a file name to hide it. In fact, Finder won't LET you start a filename with a period. You have to use the applescript above to toggle visibility on any file/folder.
