I need to buy a new charger for my 13 in aluminum late 2008 macbook and after research i believe i need to get a 60W. With the new connections, do i need to buy a magsafe to magsafe2 adapter on top of the 60w power adapter if I go the direct from apple way? Also I am new to licensed apple stores and because apple itself does not sell the original power adapter anymore, does anyone know of a licensed apple store online that I can purchase my old charger without getting a new one + adapter? TIA
