The Macbook Pro has the magnetic power connector doesn't it? In that case, you shouldn't have any problems. Many laptops have a jack that is soldered to the motherboard that depends on friction for the plug to stay in place. After repeated plugging/unplugging, or maybe someone tripping over the power cord, the jack breaks off and needs to be re-soldered or replaced. That magnetic connector pretty much eliminates the issue and is something I wish my laptop had.
