Does anyone else have problems with marks appearing in the top right hand corner of the display on their iMac. I have an early 2012 21 inch iMac and i have just noticed light brown marks have appeared under the glass in the top right hand corner of the screen. I asked if there was a known problem and was told no, if there is a mark it is usually down to a smoky enviroment. Nobody smokes in my house!
