Extracting audio from .pkgf file on Mac

Hi, this just happened to me. I found a weird way to access the audio content. Here's what I did:

1. I changed the file extension from .pkgf to .zip.
2. I unzipped the file, and it turned into a lego-shaped icon.
3. I right-clicked on the file and selected "Show Package Contents."
4. I opened the "Media" folder and then the "Audio" folder which had the audio tracks in it as separate .aif files.

It's not exactly the same as the original GB file, but at least you can get the audio tracks this way.
