Dear  Maclovers,

I got this strange ‘dust problem’ on my Mac. In December 2009 my dream came true and I purchased new lovely Apple iMac 27”, 2.66, i5. One day I have noticed dark grey smudges on both sides of the screen (left and right). I actually didn't notice any spots until I changed the background to pure white (or any other solid color really). At first, I thought it was fingerprint smudges or something. I cleaned the entire screen and it still remains.

I contacted with Apple service and they said iMac is very sensitive to dust. They call it ‘interlaminar dust’in matrix.  As time passes, dust accumulates inside the machine and irreversibly penetrates the LCD itself, causing the dark stains. They blamed environment in my room!  In fact I understand the point but there are no overt hazards like cooking locally, heavy smoking around or ventilation problems existing.  My Mac is placed on a normal work desk with lots of space around it and not more dust then in a normal house. Not that I am surprised  that  iMac is very sensitive to dust but I am so woefully disappointed.

Most people believe it was a factory defect on the LCDs. The only trouble they say is how to convince Apple Service to make a replacement of LCD under Apple repair program. They say if you pushy enough might get lucky and Apple might fix it for you.

Does it sound reasonable? How likely is it that Apple will replace LCD at their expense?

Mac fan suffering dreadfully.

George
