Hi, thanks for the inputs so far it seems like i'm pretty close to getting this to work. I got the RMMlite.jar and my Rio has an IP now from when i connected it into the router. The lights on the back of my ethernet blink. When i get on rio music manager, i put in the IP and then it says downloading but nothing loads up. When i was connected to the router i did the same thing and it did load up and it showed what songs i had available on the RIo. the only problem is now that i'm not sure how to transfer my songs from iTunes over to the Rio. when i tried sending over the folder it said that all my songs were failed in import. What is a good fix for that? maybe i'm trying to send over the wrong folder, i'm new to mac's so still learning these also. Thank you for any help.
