Why Does My MacBook Charger Turn Yellow?

If you own a MacBook, you may have noticed that over time, the color of your charger can change from its original white to a yellowish hue. This discoloration can be concerning, especially if you are unsure about the cause. In this article, we will explore the reasons behind this yellowing phenomenon and address some frequently asked questions related to the topic.

Reasons for Yellowing:

1. Aging and Oxidation: One of the primary reasons for the yellowing of MacBook chargers is aging. Over time, the plastic casing of the charger can undergo oxidation when exposed to environmental factors such as sunlight, heat, and humidity. This oxidation process leads to the gradual yellowing of the charger.

2. Exposure to UV Rays: Ultraviolet (UV) rays from sunlight can also contribute to the yellowing of your MacBook charger. When the charger is left in direct sunlight for extended periods, the UV rays can cause the plastic casing to discolor.

3. Heat: Excessive heat can accelerate the yellowing process. If your charger is exposed to high temperatures regularly, such as being left near a radiator or in a hot car, it can lead to faster discoloration.

4. Chemical Reactions: Chemical reactions with substances like nicotine, perfumes, or household cleaners can cause the charger to turn yellow. These substances can react with the plastic, altering its color.


1. Does the yellowing of the charger affect its functionality?
No, the yellowing of the charger does not affect its functionality. The color change is purely cosmetic and does not impact its ability to charge your MacBook. However, if you notice any other issues, such as fraying wires or loose connections, it is advisable to replace the charger.

2. Can I prevent my charger from turning yellow?
While it is difficult to completely prevent the yellowing of your charger, you can take some precautions to slow down the process. Avoid exposing your charger to direct sunlight for prolonged periods and keep it away from sources of excessive heat. Additionally, avoiding contact with substances that may cause chemical reactions can also help maintain the charger’s original color.

3. Can I clean my yellowed charger?
Yes, you can attempt to clean your yellowed charger. However, it is important to note that the results may vary. Start by unplugging the charger and wiping it with a soft cloth or a mild cleaning solution. Avoid using harsh chemicals or abrasive materials as they may damage the plastic casing. If the yellowing persists, it may be best to accept it as a natural aging process.

4. Should I be concerned about the yellowing affecting my MacBook?
The yellowing of the charger does not pose any direct threats to your MacBook. As long as the charger is functioning properly and not exhibiting any other issues, there is no need to worry. However, if you experience any charging problems or notice any unusual behavior from your MacBook, it is advisable to consult an authorized Apple service provider.

In conclusion, the yellowing of a MacBook charger is a common occurrence due to aging, exposure to UV rays, heat, and chemical reactions. While it may be a cosmetic concern, it has no impact on the charger’s functionality. Taking preventive measures and cleaning the charger can help slow down the yellowing process, but it is generally a natural aging phenomenon. If you have any charging-related concerns, it is always best to consult professionals for guidance.
