hi, I got two mac's with Mountain Lion and have a problem with 1 of them with getting an firefly server be visible in iTunes. I know it worked before on this Mac, but just not visible under the sharing tab of iTunes. I already had this problem with Lion as well for sure, but never paid attention to it. The firefly server is running on a Qnap NAS and i can access it from the finder without any problems. And the other Mac is working like a charm. Is it possible to reset these settings? Strange behavior is also that if i enable home sharing, the sharing tab in iTunes completely disapears (not sure if thats normal behavior though). Can someone help me with this strange issue? reinstall of iTunes is not possible anymore because its needed by the OS. tia!
