Safari: How to set your browser to download the ZIP file and not unzip/extract it

Faculty that are trying to download the ZIP file that was produced during a Blackboard course export, downloads as a file folder and not a ZIP file.  An opened ZIP file will not import to Blackboard and will produce the error:

Fatal: A fatal error has occurred. The reason for the error is:

The provided package could not be expanded or contains no file data.
For more information, consult the detailed log.
Status: The operation import did not complete.

This is happens due to a setting in Safari that automatically extracts the contents of a ZIP file when it is downloaded. To  fix this and download the file in an unopened ZIP format:

  1.  Open Safari
  2.  Open the Preferences menu:
    In Mac OS X: Click Safari > Preferences
  3. In the window that opens, click General
  4. Remove the check from the box beside “Open ‘safe’ files after downloading”
  5. Download the file again

Now try the Blackboard import again with the new file.
