What is the MagSafe Connector?
Apple has redesigned the way the power charger connects to the laptop. (Yes, laptop users who have collected a zillion power adapters, this means you’ll have to invest in all-new adapters.) The MagSafe Connector uses magnets in the cable and the computer to secure the connection. Apple did this to prevent accidental cord snags that can damage the laptop while creating a more snug link between the two parts. The MagSafe connecter is made up of a magnetic ring surrounding four small power nubs; when you move it close to the MacBook, the magnetic attraction takes over and it snaps in place. There’s no up or down on this connector—it’s perfectly symmetrical, so either direction works fine. A small light (on both top and bottom of the connector) indicates your MacBook’s charging status.
