When connecting to Sakai using Goliath (for Mac OS 10-10.3), users cannot create new folders remotely and cannot drag existing folders from their hard drive to Sakai.
This is highly problematic as the instructions on the system instruct users to use Goliath for Mac systems.
The native WebDAV in the new Mac OS 10.4 (Tiger), does not have these problems. Users can create folders and drag in existing file structures from their hard drive without problems.
However, there are no instructions for how to connect using the native Mac OSX 10.4 WebDAV (it's pretty easy - just Command-K from the finder, and then enter the URL in the box)
