Cool! Glad you've got it going.
Shared drives - I suspect you have credentials for connecting? Whatever account is running in the background needs permission to connect to your shared drive.
I haven't added credentials in TabloRipper, so you'll need that account to have permission by default. One way to accomplish that is to have a special folder that allows everyone full access. Then only use it for rips.
PS: Not sure if this helps, but I posted a link to a post that explains how one person got things going on their Mac.
