Make sure that the power adapter is disconnected from the wall outlet and MacBook.
Use a pen to make a mark on the MagSafe cable about 4" (10 cm) from the MagSafe connector.
Use a pair of wire cutters or scissors to cut the cable at the mark you made about 4 inches from the MagSafe connector. Set aside the MagSafe connector wire for later.
Although the wires inside the cable are copper, they may damage some scissors. We recommend using wire cutters if possible.
