There's got to be a second ~/Library...YOUR OWN.
Nope. That's what I thought. In the Users folder, rather than a folder with my name, there's a picture of a house (Home?) with my name….along with Folders that have other Users' names. Clicking on the House reveals these folders:
Applications
Desktop
Documents
Downloads
Dropbox
Magazines
Microsoft User Data
Movies
Music
Pictures
Public
Sites
There is nothing named Macromedia in any of them.
