There have been many problems with the screens on the 27inch iMacs and Apple has issued another firmware update. Apple states that the issue is “intermittent display flickering” but people have been having many other issues with the display. Apple finally released this firmware update after 500,000 views on the Apple Discussions Forum. The original update did not fix the issue but hopefully this update will fix the issues once and for all.
Have you been having any problems with the display? Did the update fix your problem? Leave a comment down bellow.
