Mac Charger Turning Yellow- How To Fix?

If you’re in the Apple ecosystem, you know how good and reliable Apple’s products are. From its iPhone to Macbook, the performance is solid. Sadly, this device’s charger & cable gets yellowish over time. But why is that?

MacBook charging gets yellow due to physical contact, excessive heat during charging, or frequent exposure to UV rays. Overheat makes the cable’s outer jacket hard and yellowish. To prevent that, keep the cable out of sunlight and clean it.

Apart from these, you must know some factors behind this discolored Mac charger & cable. So, if you want to know those and how to prevent it, stick to the end. Let’s begin!

Why Did The Macbook Charger Color Turn Yellow?

The Macbook charging cable gets yellow after using it for around one year. If you own one, you already have noticed it. Moreover, the cable’s outer jacket is rubber-finished and contains no PVC. It’s porous.

The cable absorbs dust, oil, dirt on hands, and sweat sticking to fingers. So, you might have noticed that where you grab the cable most, that portion turns yellow soon.

However, besides this, other reasons made that cable yellow. Let’s explore those reasons one by one.

Excessive Heat During Charging

Overheating is one of the leading causes primarily responsible for turning both ends of the cable yellow and damaging the cable. As you know, the cable top jacket is rubber-coated and made from porous.

So, when you’re charging the MacBook, the wire underneath the top cable jacket gets hot. But that’s not a matter of concern. However, the cable cover gets affected and swells when it gets excessively hot.

And in the long run, both ends of the cable get yellow and lose temper. Within a few months, the rubber protection breaks off.

Frequently Exposed to Sunlight

The rubber protection in the Macbook charging cable has no color stabilizers or UV protection. So, when the cable gets exposed to sunlight frequently, it becomes yellow or degrades slowly.

The MacBook charging cable and most white, light color, and clear coated cables degrade faster due to UV rays. So, if you expose the Mac charger and cable to sunlight most of the time, the entire cable will turn yellow faster than expected.

Speaking of the MacBook charging adapter, it’s made from ABS(Acrylonitrile butadiene styrene), a type of thermoplastic. So, this adapter gets yellow due to oxidation and UV rays from direct sunlight.

Plus, heat generated while charging also makes its color yellowish.

Dirt from Your Hand

The charging cable absorbs all types of dirt from your hand and surroundings. That rubber-type upper protection becomes yellow over time due to dirt.

Suppose you wiped your sweat and grabbed the charger to juice the Mac’s battery. That sweat will stick to the cable, and the rubber protective jacket will get dirty.

So, that process continues countless times, and the cable turns yellow due to a chemical reaction. That’s why you end up with a yellowish cable.

If you look closely, you’ll find that the yellow color mainly occurred in both ends of the cable where you usually hold.

Yellowish MacBook Charger & Cable- Can You Still Use It?

MacBook charger will turn yellow after long usage or frequent exposure to the sun. But, if the cable has a major fault, you mustn’t use it. Conversely, you can still use that if that color changes for longer usage.

So, find out if there is any swell in the yellowish area of the chagrin cable. In that case, the inner part of the cable might have burnt or damaged badly. So, it’s recommended not to use that damaged cable.

It might cause you an electric shock or damage your Macbook pretty hard.

The fact is, not only the MacBook charging cable but almost all the white charging cable gets yellow after a certain period. So, if that color changes happens to the entire cable and no swell at all, it’s safe to use.

Plus, the degraded protective jacket gets hard and peels off slowly. The stripped inner wire might give you an electric shock. So, take your charger and cable to nearby Apple Care if it turns yellow.

Lastly, examine the cable thoroughly and keep in mind the above factors. But changing the charging cable after one year of usage will be wise.
