Hi Neil, When I read your first posting to the mailing list; the Console Log messages that jumped out at me were these messages: 1) 14/10/13 12:14:32 com.apple.usbmuxd[11654] LOCKDOWN_V2_BONJOUR_SERVICE_NAME is _apple-mobdev2._tcp,930d07f5 2) 14/10/13 12:16:43 mDNSResponder[18] Client application bug: DNSServiceResolve(53F5FEFC2612ED6D._appletv-v2._tcp.local.) active for over two minutes. This places considerable burden on the network. I thought at the time... "ah perhaps a Bonjour issue"? iTunes uses Bonjour (as well as other Bonjour-compatible devices and services). Now after reading your last message to the mailing list and thoroughly going through your "full unfiltered console log" and noticing the "mDNSResponder[18] ERROR messages 15/10/13 11:57:51 mDNSResponder[18] ERROR: handle_resolve_request bad interfaceIndex 1 - down to 24 I'm pretty certain that my original assumption was correct and Bonjour is involved. My reasoning for coming to this conclusion is: The process that makes Bonjour work is mDNSResponder, located in /usr/sbin. /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist invokes mDNSResponder on boot. NOTE: I don't want you deleting the .plist above I only mentioned where it is located ;-) What I would suggest you do is Reset / Clear the DNS cache. OS X keeps a local cache of resolved DNS queries for a time defined by the DNS server, but sometimes it may be necessary to reset the cache. In Lion & Mountain Lion, Apple has changed the caching routines done by the mDNSResponder process (the core process responsible for DNS resolution) so they are kept in memory by the process as long as it maintains a connection to the DNS network. Therefore, to clear the cache, you just need to send the mDNSResponder process a hang-up command to have it reinitialise its configuration without being fully shut down and restarted. To do this, you can run the following command in the Terminal: sudo killall -HUP mDNSResponder Note the dscacheutil still exists in 10.7 and 10.8, but the official method to clear out DNS caches is through killing mDNSResponder. OR - you can use Activity Monitor - In addition to the killall command in the Terminal, you can also do this in Activity Monitor by the following process: 1. Open Activity Monitor (in the /Applications/Utilities/ folder). 2. In the main Activity Monitor window is not present, press Command-1 to show it. 3. Locate and select the mDNSResponder process (you can search for it to make this easier). 4. Choose Send Signal To Process from the View menu. 5. Select Hangup (SIGHUP) from the menu that appears (it should be the first option that is already selected). 6. Click the Send button. When you do this, you may see another mDNSResponder process appear for a few seconds in Activity Monitor as the system reinitialises the process, and once this disappears, the DNS cache should be cleared. That's it! ... for today anyway ;-) Cheers, Ronni 17" MacBook Pro 2.3GHz Quad-Core i7 “Thunderbolt" 2.3GHz / 8GB / 750GB @ 7200rpm HD OS X 10.8.5 Mountain Lion Windows 7 Ultimate (under sufferance)
