Engadget reported earlier this week that MacBook users were complaining about discoloration of their 1-month old laptops. Users have already started to blame Apple saying that this is a manufacturer’s defect.
However, some brave people have found a temporary solution to the problem. The discoloration can reportedly be removed by using NON-ACETONE based nail polish remover. Make sure that there is no Acetone in the nail polish remover otherwise it will start to eat away the plastic. Even though this appears to have worked for many people some still say that they are going to wait for Apple to release an official solution to the issue.
