    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.
    [​IMG]
    then connect the inner cable and afterwards put the heat-shring tubing over it
    [​IMG]
    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!

    Can't say I'd feel safe plugging that into my macbook and least so the wall outlet :eek: But i'm glad it worked out for you

    Magsafe fray repair

    I thought it was risky at first, but after doing it, I feel perfectly safe. Both cables are seperated by two layers of rubber.
    im my opinion it's probably safer that working with a frayed/half broken magsafe.
    It does LOOK ugly (was not important to me). The idea was to put 5 layer of heat shrinking tubing in/outside the cable, because it makes it stable and minimizes the risk of breaking again.

    Nice work and that actually looks stronger than the original setup. I don't see what is risky at all. It is just two low voltage wires separated by insulation and you have replicated that (maybe even improved it).

    White electrical tape is working for me. There is also a product called liquid electrical tape that is available in white. I have used the black liquid version to repair similar problems and I am surprised by how well it holds up. Obviously, one needs to use either of these two products before the fraying gets out of hand.

    nip it in the bud

    My Sis is a PHD candidate in Chemistry

    She gave me some stuff called "Sugru" for X-Mas last year.

    I stuffed it in a drawer and forgot until I noticed my rMBP cord was fraying.

    Mixed it up and clobbered it on, has held for 4 months or so.

    Not pretty but I have held the fraying at bay.

    Very similar to Liquid Electrical tape that I suggested. Maybe I can find Sugru in white locally.

    Thread jack ahead! :)

    How does that stuff look/feel once dry... is it fairly rugged? I was going to use it to on some garage door sensor wiring.

    The black liquid tape is smooth, shiny and pretty stiff after drying. You might try a practice run on something not crucial if you are concerned about how it looks. I am sure if one practiced you could perform works of art with the stuff. <g> I repaired some solar sensor wiring that raccoons had torn up. I was surprised how well it held up. I also have repaired fraying on a flashlight recharger and tire inflator with it. Both are holding up well. I looked at several hardware/big box stores for the white version to no avail.

    Macbook Power Supply Fix

    I have done this on several of my power supplies, it works and if done carefully there should be no issues with safety. Over the past few years, I have fixed and purchased at least 8 of these units, and I feel that it is a major design flaw with the way the units are constructed.

    About half of the failures are at the brick end, and the other half are at the magsafe end, just snip the cable, and splice as needed.

    What apple should do is construct the units with a magsafe connector at each end, and then all you would need to do is replace the cord.

    Thanks for the write-up, but I have found consistantly Apple will replace these things under warranty especially for fraying.

    Personally none of my cables have ever frayed, but I have take my friends' adapters in with no issues.
