Modify Macintosh HD disk
So I was doing some stuff with my applications folder, and somehow, my user applications folder got copied to Macintosh HD, meaning that now there's an applications folder in Macintosh HD that all users can access / have their applications default to. It's not a huge deal, but I want to remove it. Of course, though, I don't actually have write access to Macintosh HD, and I can't give myself access. Does anyone know how I could get rid of the folder?
