在我刚刚入手的这台上，屏幕的下半部分确实是发黄的。而且，Apple 在今年 2 月 1 日发布的这个更新 27-inch iMac Display Firmware Update 1.0 看来对问题解决彻底没有帮助。根据我的实际使用体验，用的时间越长，屏幕貌似越黄。

我预计这件事情最好的结果是一次全球召回。记得很多年之前，我的一台 PowerBook G4 就因为屏幕白斑问题享受了一次召回。还有一次，是一台 iBook G4 因为电池问题召回。希望苹果这次召回能够不影响到用户硬盘中的数据。

UPDATE: 有一份貌似苹果内部的文件流出：

而他们目前能够提供的解决办法是：

Do not attempt a repair or replacement at this time. Explain that slight color variability is normal for LCD displays and in general does not warranty replacement. Customers who are concerned that their iMac has a yellow tint issue, and who provide contact information, will be contacted by Apple in approximately 3 weeks to arrange a LCD panel replacement. Those who do not wish to provide contact information can contact Apple in the future for the latest information. Customers who require an immediate resolution should be offered a refund.
