My Macbook's display has been great for the past 2 and a half years, but recently the whole assembly had to be replaced by apple due to a cable issue, and this new display is displaying what seems to be a common issue. At the lowest brightness setting, which I frequently use to save power and reduce eye strain, the display (read:backlight) flickers. I have noticed that this plagues all of the iMacs (first iteration with a completely metal enclosure, 2010?), at least the ones I have used, in my school's computer lab. And this is NOT a smooth change in brightness due to changes in ambient light. This is a known issue: http://forums.macrumors.com/showthread.php?t=596727 http://forums.macrumors.com/showthread.php?t=593188 So what can I do? Any fixes? Since I just got this part replaced, I can go back and get it replaced at Apple for free, but I'd like to see if any other ways have been discovered first.
