This all started when I had to sync a new Nike+ sensor... I was trying to upload two missing runs with my 3rd gen nano (windows formatted) and the folder on the ipod is not listed when I access the ipod from finder. I thought I would use my new iTouch, 3rd gen, and now it does now show up as a device in finder. It does show up as a device in iTunes, ver 9.0.2. I am running Mac OS 10.6.2 on a 13 in Macbook. I have the itouch connected with the supplied usb cable.
When I try to connect to my wife's iMac, it shows up in iTunes, same version, but does not show up in finder. She in running the same version of Snow Leopard, 10.6.2.
