Now that I’ve repaired this cord in the way I share below, I need to confess that this did not turn out to be a good long-term fix. This method has worked find on the magsafe end but since the power brick gets hot, it melts the electrical tape and you end up with this situation:

I have repaired my cord in another way, which is going to last a long time and I share how in another blog post here: How To Repair a Fraying MacBook Power Cord – Take 2
Repair Attempt 1 (if you’re curious as to what didn’t work well):
I just noticed that of my MacBook Power Cords just started fraying. I didn’t want to let it get bad before I protected it. The best thing to do would be to put some heat shrink tubing on it but unfortunately the magsafe adapter on the end of the cord is pretty big and the heat shrink tubing that will fit over it won’t shrink down tight over the cord if it’s big enough to slip over. You could just put a couple wraps of electrical tape on it but electrical tape just gets all sticky and doesn’t last very well. So I chose a hybrid solution.

| Wrap electrical tape around the frayed area |
Step 3: Slip the heat shrink over the magsafe connector and over the electrical tape.

Step 4: Use a heat gun to shrink the shrink tubing over the electrical tape. Be very careful because you could really burn yourself with a heat gun.

Finished product:

| MacBook power cord repaired with electrical tape covered in heat shrink tubing |
It’s not the most beautiful thing but it definitely extends the life of the power adapter. I used this method to repair a different power cord on the MagSafe end and I was pleased with the result:
