I have a brand new mac pro, just got it about 3 months ago. It runs beautifully. The only problem I've run into involves the iPhone. Every time I plug it in, the keyboard stops working. If i unplug/re-plug the keyboard in, it works for a few minutes, then cuts off again. Has anyone else experienced this problem? I'm thinking it's just a hardware issue that i'd have to resolve via the apple store, but I'm hoping thats not the case. I figured i'd just check here first.
