nope magsafe is magsafe
Not really. MacBooks use 65w and MacBook Pros use 85w. It doesn't really matter which you use. If you use a 65w with a macbook pro it will just charge at 65w. If you use a 85w with a macbook it steps down to 65w. So it doesn't matter which you use but Macbook pros charge slower with a macbook charger.
