When I updated iTunes it seems to have messed up everything. Now neither of the Apple TVs in my house can access my iMac where I keep all my movies, etc. I scroll to the Computer app on the apple TVs and its like they don't see the iMac. I have tried turning homesharing off and on on both my iMac and apple TVs with no luck. Also, my remote app on my phone doesn't seem to want to connect to the iMac either. Has this happened to anyone else? Any other troubleshooting tips?
