Why Is My Macbook Charger Wire Yellow. Hotdogsladies Same thing has happened to me on every Lightning cable Ive used. Yellow Light On Power Cord.
The plastic is turning yellow because it is oxidizing and aging faster. However the staff at Apple always tell me its when stress is. I kept it plugged in all day yesterday and the charger light never went green.
Check power If the power adapter shuts off interference might be affecting the power outlet youre using.
When I went back to the first charger on my machine the light then stayed amber but the machine would not boot and would not even make the startup chime sound. The charger works by using a transformer to convert the AC line voltage coming from a wall outlet to the DC voltage required to charge the battery. Depending on how old the charger is it is possible the agent causing the discoloration is leaching through from what the casing covers instead of being caused by an external source. I recommend Anker cables as theyve lasted me a long time and are much cheaper and more durable than my old original lightning cable.
