MacBook does not recognize iPad
We had some customers in our store with similar problems. Mainly they came with an iPhone 2 / 3 and asked for help because their Macs won't recognize them. Some (not all devices!) worked on an older Mac with OSX &lt; 10.7 and a lower iTunes version. If you have a friend or family member with an older Mac try to connect to this one.
If it's not working I would say the iPad is "bricked".
