The shield is made from a fine wire that is "braided", and runs the length of the cable. Look after your MacBook charger as well as you look after your MacBook, and you’ll never have to worry about it.I guess tha the "coaxial" part you refer to is actually just a shield. However, if you follow the steps above, you should avoid your charger becoming frayed and damaged and the wires exposed. However, in the short term, you can wrap electrical tape around the frayed part of the cable to cover the exposed wire.Ī frayed MacBook charger is very annoying and can be expensive to fix if you need to replace a MagSafe charger. In the medium-to-long term, you’ll have to replace the cable, or the whole charger, depending on whether it’s USB-C or MagSafe. USB-C MacBook chargers don’t have a power adapter with hooks to wrap around, so it shouldn’t be too much of a temptation to wrap as tightly as you can. While wrapping your cable tightly might keep it neat and won’t cause it to fray, it can damage the wires inside the cable. If the cable of your Mac charger rubs against anything like that, it could cause it to fray. That sounds obvious, doesn’t it? But ‘sharp objects’ doesn’t just mean knives it can mean anything with a narrow hard edge. The most vulnerable part of the cable is near the plug, just behind the collar. If you’re worried about your charger fraying, there are a number of products available that can provide added protection. If you need to bend it, make sure you bend it loosely, so it snakes around gently. When you plug the cable into your Mac, it should be at an angle of 90 degrees or as close to that as possible. If you can, choose a bag with a separate compartment for the charger. Don’t wrap it up too tightly and put it in your laptop bag carefully. The simplest solution is to treat the cable and charger with as much care as your Mac. The problem is that wrapping the cable too tightly or putting it somewhere where it will rub against a hard edge will, over time, result in the rubber sheath becoming damaged, putting the cable at risk of fraying. We wrap up the cable and throw it into our bag without a second thought. Most of us take care when we put our MacBook in a bag or sleeve, but the same can’t be said of the charger. In a few cases, it could be that the cable itself has a flaw, but the most common reason is that the chargers are not properly looked after. It can also reindex Spotlight, run maintenance scripts and free up purgeable space. CleanMyMac X does just that by freeing up RAM when there is too little left to run your Mac properly and repairing disk permissions. While there’s nothing that any software can do to stop your MacBook cable from being frayed, you can keep other hardware and your boot disk in good condition.
