I'm a Mac user. ~ should be home directory, but it is possible the files get saved in the user directory. If that's the case, just press Command+Shift+G (go to command) In the text box that opens, write "~/". You can copy and paste from here, if necessary.
[edit]
I just looked...I'm wrong, they are right. ~ is user directory.
However, if you are looking for the home directory, press Command+Up, the arrow key. It jumps backward to the folder above the one you are in.
