I love my MacBook Pro. I HATE it when the magsafe end starts to age out and the cord cover starts to split and crack. Having to drop mad cash because plastic doesn't last forever makes me crazy. So I have applied an old boy scout skill for keeping the frayed ends of rope from unraveling to this 21st century problem to add a few months to the life of my power cord.

Supplies

I usually use dental floss instead of the synthetic twine I used for this tutorial, but the fat white string is easier to see in the pictures. And just think: you don't need a 3D printer or a lathe or a full shop of electronic tools to make this happen.

Step 1: Set Up the String and Cord to Wrap

The first step is to cut a piece of the string you will use to about 4-5x the length of the end of your cord which needs to be covered. This isn't rocket science, and string is (still) cheap. just cut enough that you will be able to cover the worn-out area, but not more than you can handle with two hands and not create a giant knot.

Take one end of the string and lay it down at the end away from your Magsafe connector. Leave 2-3 inches past the last crack in the wire casing.

Take the rest of the string and extend it to the connector, then loop it back to the start of the string. The loop should extend a little past the connector. You should have ample string now hanging down at the end where you starters

Step 2: Start Wrapping

Keeping the 2-3 inches free on the starting end of the string, start winding the long end over the string and your cord. Wrap it tightly but not so tight that you cause the casing of the cord to start to buckle or bulge. Wind away from the starting end of the string toward magsafe connector, keeping the turns of your string as close as possible. Keep winding until you approach the end of the cord where the string is sticking out as a loop.

Step 3: Wrap Until You Can't Anymore

Wind down toward the magsafe connector until there is only a little bit of the loop left. If you did a good job, you would have done better than what is in the picture above -- you'd have 3-4 inches of the end of the string, and a loop at least 1 inch in diameter.

Feed the end of your string into the loop, and hold it with one hand.

Step 4: Pull the Loop Back Into Your Wrapped String

If you wrapped tight enough (but not too tight), you should now be able to pull on the loose end away from the madsafe connector and tug the loop back under the wrapped string. if you threaded the end of the wrapped part back into the loop properly, when you pull the loop under the wrapped string, you will also be hiding the end of the wrap inside the tight body of the wrap. Pull it in about 1/2 inch (1-2cm), leaving a frayed end by the MagSafe connector.

Step 5: Trim the Ends

Trim the loose string off the Magsafe end and the other end where you pulled tight. Again, if you wrapped tight enough, both ens hide under the wrapped part without a lot of trouble or worry that they will come undone.

Step 6:

Done! You now have a safe and flexible end cover for your cord which should last a good while. It's also flexible and easily replaced. The only time you should need to replace your actual power supply now is if the actual wires wear out - and this solution actually prevents them from bending too far and breaking due to kinks. Enjoy!!
