However, it seems they also have a version for the USB-C to Magsafe 2 cable which may suit your situation. Consequently, the cable I bought will not work for you. It appears from the picture you have the newer Magsafe 2 connector. I've been using it for several months now & it works. This cable allows me to use one of the new USB-C chargers to charge my 2011 Macbook Pro. I was able to find this replacement Magsafe cable on Amazon. I also used electrical tape as a temporary solution. The outer insulation in one area on the cable just began breaking down, and falling off the cable! I've never seen wiring insulation behave like this. I had the same problem as you recently on my Magsafe cable. As long as the electrical tape is in place, and in good condition, I don't believe the cable poses any risk to you, or to your Mac. You have done the right thing by mending the cable with electrical tape: it's an insulator and it's flexible. It's important all of the inner wires (inside the shield) are in good condition. Also the question is, what are the flaps on the Macbook charger for The wings on the adapter allow the cable to be stored with the adapter. Apple will replace chargers for up to one year, but not ones that are fraying or show signs of wear at least not for everyone, that is. However, the insulation on the wires in the cable should be checked for evidence of cracking, fraying or other deterioration. Amazingly, does Apple replace frayed Macbook charger Yes. That said, any damage to the shield is unlikely to affect the function of your cable. Using a shield as a conductor would be unusual to say the least. I'm not privy to Apple's designs or schematics, but most likely the shield is there for EMC (electromagnetic compatibility), and not as a current-conducting ground wire. The shield is made from a fine wire that is "braided", and runs the length of the cable. Its curious to because this could be a potentially dangerous flaw too.I guess tha the "coaxial" part you refer to is actually just a shield. Good Luck and I hope the new breed of chargers doesn't cost 79$ or fail so easily.
If you use heat shrink tubing instead (which I have had good results with in the past) make sure you slip it on before you start! Congrats on fixing a problem Apple should have never had! Please send me your ideas on how to make this a more friendly process, I would be very interested. In reality i think that I always pull on the cord to unplug the charger so I opted for hot glue hoping it would take better straight on yanks vs shrink tubing's side-to-side protection (who knows though). I used hot glue, making sure to apply at least the first large blob all once in one blast to ensure uniformity. Solder your connections and use electrical tape on the unshielded wires to protect from shorts. Split the outer sheath wire into two equal groups and tin them to connect to the two points on the MagSafe. I removed the rubbery plastic that is used to secure the joints enough so that I had something to solder to (soldering iron melting and exacto surgery). Exacto Knife (Skilled use of a dremel could save you a lot of time too!) 4. Skills Required: -Adventurous case cracking -Exacto surgery -Hot glue sculpting -Soldering wires Materials necessary: 1. Preparing the Power brick for soldering/ soldering. Preparing the Magsafe connector for soldering/ soldering. In this Instructable I will cover opening the power brick case via brute force. As the days went on, it was harder and harder. A few minutes later, she noticed it was also frayed near the Magsafe connector, so I covered that with tape as well. We found a small fray in the cable near the brick, and I immediately covered it with electrical tape. You must be making a killing on these chargers. Last week, my wife noticed her Macbook Air wasnt charging. You can do it! Apple you should be ashamed of yourself.
This instructable is to provide hope for people who must forgo grocery shopping this week if they plan to buy a new charger. Apple knows about this problem, but they have done noting to remedy it. If they do not replace it then start working on this instructable. I would cite reviews on the apple store website if they do not replace yours. You may want to take your charger to apple straight away and see if they will replace this charger. If you use the tabs that fold out and allow you to wrap the cord around the brick you are probably reducing the life of you charger. Eventually the rubber sheath separates from the MagSafe connector or the Power-brick and the wire begin to fray or short, sometimes affecting charging and sometimes smoldering. The wimpy wire used in the design is simply to weak to take any real stress, coiling, and yanks. Apple really dropped the ball on the design of this charger.
