Any idea how to fix the broken plastic/rubber covering of the cable on a MagSafe Power Adapter? Mine is showing the inner wires and I'm afraid of getting an electrical shock.
Eventually there will be very light electricity shocks, I fixed all my cables with this tape it is very strong an the with ones are more esthetics for mac white cable.
It's called RESCUE TAPE Self-Fusing Silicone Tape ~ WHITE. I got mine from Amazon but there might be other places or similar tapes.
Sugru - not cheap, but very good.
Goes on like Plasticene/Silly Putty, dries like rubberised plastic. Flexible & waterproof, lots of different colours.
