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