I did it a couple days ago and my logitech transporter would no longer talk to my mac mini...but my SB Touch worked fine. After tearing out what little hair I have left...it took a hard reset on the Transporter and a reload of Logitech Music Server to get the two talking to one another again. Of course, I should mention that if you haven't upgraded your mini to more memory, you will find that even after the slow download, it took more than an hour to install. Just sayin'.
