This isn't a question, but my story of how I fixed my frayed Magsafe. (there is probably somewhere a thread like this, but I couldn't find it and thought, maybe it's helpful). I don't have much electrical knowledge, but had some help . It worked for me, but I can't guarantee that it will work for you (neither that it won't damage the magsafe or even the macbook) With my now ~4 years old Macbook Pro I have used 3 Magsafe chargers - all three broke shortly after one year. I read that in the US (and other countries with Apple Stores those are often exchanged for free, but not here in Austria [no real Apple Stores, only Serviceproviders here). So when my 3rd one broke, I decided that there has to be SOME way to fix it. I googled and found a video (https://www.youtube.com/watch?v=hOb-8Tutt7M) I tried it with one of the older Magsafes and it DID NOT WORK The problem is, that it seems, that Apple decided to put huge amounts of glue inside. So I was looking for another solution. To find another, one first has to find the real problem. Why fix the connector, if only the cable is broken?! So there are two cables inside. There are two different types of frayed Magsafes: the one where the outer insulation breaks and then the outer cable. In the second one the whole inner cable breaks (both the cable and the isolation). From the outside this looks the same as the fist. I removed the insulation and separated both cables. (and also removed the insulation of the inner one). The general idea: if they are properly connected, it should work, so I tried it: Success! Next step: make it last! Get some Heat-shrink tubing (mine is actually a bit too big, but it's the only one we had). You will also need a soldering iron and tin. then connect the inner cable and afterwards put the heat-shring tubing over it same for the outer cable I put a huge heat-shrink tubing over it, because the movement of the cable is, what damages it. I hope this will work for some of you guys too and you can safe some money too!
