I agree. Doesn't look like a cable issue at all.Warbrain said:It doesn't look like it came from the wire but from an external source...

Internal overheating would be most unlikely to cause superficial damage to the flex.alexprice said:Typo in last post. Meant to say "I'm not sure".
Sunfast: Correct, it was plugged into a MacBook Pro.
Warbrain: I'm pretty sure thats there's nothing else that would have caused it.
Its a mystery!

Warbrain said:To me, it looks like something melted the cable from the outside, especially with the crater that appears to have formed on the casing.
I don't have photos, but I noticed a burning plastic smell while using my macbook. (No other heat sources were nearby in my office.)
The main transformer body (model A1184) was extremely hot, and the cabling about an inch upstream of the magsafe connecter was melting/smoldering and HOT.
I unplugged, bought a new one, and all seems to be going okay now.
After cutting/stripping the old cable upstream of the short/over-current, the transformer body stays cool when plugged in (though of course there's no load on it). Oddly, instead of reading the nominal 16.5VDC, my multimeter reads (steadily) 6.86VDC across the two conductors.
Also unfortunately, the melt was so close to the magsafe connector that I couldn't harvest it for re-dedication. :/
Now I'm sorry I didn't take pictures before ripping it apart-- it looked very similar to the photo above.
