I am new to Mac computers so I was wondering about the shared devices. I noticed the other and today, there was a device under the Shared that I did not know what it was. My wifi is password protected and WPA2. I had never seen this before under Shared. Usually there is my iPhone, iPad, and another computed hooked up to the WiFi, and this was the first time seeing this device under shared. Here is a link to the screen shot http://i49.tinypic.com/vpi9fs.png Does this mean this device was sharing files from/with my computer? Is there a way to disable this?
