Thanks for the response. I have followed all the directions in the manual on page 180+ to configure the H8000fw for Macintosh Output. Nothing works. I even updated my drivers for Snow Leopard just to rule that out. I literally have tried every single option possible when it comes to setting up the aggregate device.
I don't want anyone to think I'm trying to busk through this, as I understand the Manual is a key ingredient to mastering this piece. However, the set up is beyond my ken. And I just don't understand why it's not working. Furthermore, it still doesn't show up under the "other" section of system preferences.
