Apple sells "MagSafe to MagSafe 2 Converter" MD504 A1464. Around WWW people have asked "Is there a MagSafe 2 to MagSafe Converter?". I found no reports of a homemade converter, so maybe I am first? I made two cable assemblies: MagSafe 2 inlet to 5.5 mm O.D. 2.5 mm I.D. barrel plug; and 5.5•2.5 barrel inlet to MagSafe 60W plug lead.
