Richard has a previously-purchased 85-85W MagSafe Power Adapter and would like to use it as a spare adapter for his MacBook Pro (Retina, 13-inch Late 2012). Which of the following is a valid statement? 

MagSafe Power Adapters are not supported with newer Apple portables; the customer should purchase a new spare adapter. 

The correct wattage for the MacBook Pro (Retina, 13-inch Late 2012) is actually 45W, so the adapter should not be used. 

Use the older MagSafe power adapter on the newer computer with MagSafe 2 port by using a MagSafe to MagSafe 2 converter. 

The customer can only use an older MagSafe power adapter with a new portable if it has an “L” style connector, not “T” style.
