So Apple was nice enough to replace my year old Macbook Air Magsafe cord. I inspected the new cord and it appears to be the same design and material, so no doubt it will fray again eventually.. I've been careful with the cord since I bought the Air because I've had 2 other friends who had cords fray on them. But I still managed to fray it. So any suggestions on how I can uhm, reinforce, the connector? It's the L connector and happens below the connector. Wrapping it with electrical tape?
