A support thread in Apple’s Discussion forums is abuzz with 2011 MacBook Pro owners having issues with iTunes Home Sharing. The users are having issues connecting to certain iOS devices as well as having devices disconnect and display error messages.
The user who started the discussion thread; ‘themacbear’, reported that his new 17 inch MacBook Pro initially seemed to work fine using Home Sharing with his Apple TV. However later on in the day “…although the Apple TV could see the name of my iTunes library, it wouldn't connect to it, or sometimes, would report that "There are no movies in this library". I tried every solution I could think of, but no dice.” He went to an Apple Store, which managed to replicate the issue on a different MacBook Pro, but couldn’t resolve the problem and consequently gave 'themacbear' a full refund. Others too have contacted Apple through their retail stores and via phone support but so far there is no fix for the problem.
Apple recently beefed up its Home Sharing features with iOS 4.3 and iTunes 10.2 and it could be that the issues these users are facing are related to these updates. Furthermore there are also some users with older Mac’s also having similar issues, although this seems to be a more isolated group of users.
