ZIP Downloads fail in Safari

This is Safari browser specific issue. We stream zip downloads and Safari will extract the first file and then discontinue the stream after the first file is extracted.  This can result in what appears to be a successful download but no data is present.

As a workaround you can do the following:

Apple > Safari Preferences > General. At the bottom un-check "Open 'Safe' files after downloading"

Another option would be to use another browser such as Firefox or Chrome.
