How do you work Maplestory on a high school laptop

If it's a mac computer... can't help you with that. Macs don't allow maple and most mmorpgs and programs. Unless you download Microsoft into the mac which can get you into trouble if your renting the computer or get checkups by the school. How to do that? no idea but i know people who did that. If its windows then it will be the same way how you download on a desktop windows computer.
