Can I use "Share my library on my local network" ? I have my library in a shared folder on my iMac, this is to stop having to have the same music stored twice so my other half can use iTunes as well as me. I was told not to turn this on when helped by apple phone desk when setting this up, but that was quite a long time and updates ago now. I would like to airplay my music to an ATV.
Using iTunes 11.3.1 and Mountain Lion.
