Here's the machines involved 15" late 2008 Unibody Macbook Pro "Upgraded" to Snow Leopard 2006 Quad Core 2.66 Mac Pro "Clean Install" Snow Leopard 1st Gen Macbook Air "Upgraded" to Snow Leopard 13" Macbook Pro Unibody "Upgraded" to Snow Leopard The first two machines are mine, the MBA is my fathers and the 13" is my brother's in Tx. It seems when we try and video chat (one on one), Snow Leopard to Snow Leopard, the audio will not connect consistently. We'll have video, but one side won't be able to hear the other or no one can hear anything. Seems quitting and restarting iChat and reconnecting/disconnecting and eventually it will work...but it's quite annoying. Anyone else see this?
