OSX Error When Dumping Patch - Could not extract file "".

[coryshaw1]

Before I begin I must note I had to change a few things in the script to support OSX.

1. Replace all instances of mkdir --parents with just mkdir -p
2. dd does not have a --version flag on OSX so I just updated L870 to dd --version 2> /dev/null | grep GNU > /dev/null

And finally for the error. I ran in debug mode to get more logging:

I'm guessing something with the partial file download is failing on OSX using dd.

Any ideas here?

Editing with an example from attempting to dump a base game with app.pkg:
