Not sure if it's the latest update or what. But it was running smooth just days ago. Apple Tv3 with the latest updates, on wireless network. Running to an Imac with the latest version of Itunes. I have a fairly large library, 2.5TB. At my wit's end I've restarted, reset, restarted the mac, restarted the router etc. Wife is not amused, any help would be appreciated. Thanks ---------- Fyi, the Imac is a late 2013 16gb ram 15 3.2 on a wired connection.
