MacBook users complain of yellow discoloration
Owners of white MacBooks are reporting a yellow discoloration mostly on the palm rest area of the device, according to a growing number of members on an Apple Computer discussion board.
The discoloration seems to be occurring after just a few weeks of use. MacBook owners experiencing the problem have tried an array of cleaners, to no avail.
An Apple representative could not immediately be reached for comment and the company hasn't responded yet to the discussion board.
Some surmise that the yellowing is caused by heat coming from the device combined with hand grime.
Earlier this month, Apple acknowledged a different problem with the MacBook, which was released in mid-May. Some MacBooks were coming from the factory with a plastic film covering the rear exit vent, which made them run hot.
