Does anyone know what the first layer inside the MacBook Pro’s power adapter cable (the end with the MagSafe on it) does? Is it the ground, or is there current running through it? I just noticed today that after a year of winding and rewinding it, the outer jacket has pulled out of it’s mount in the end. If it’s just the ground, I’m just going to get some heatshrink and wrap it. If it’s something with live current running through it, I’ll be a little more careful.
