We know that Apple boffins have been working on a fix for the 27″ iMacs, but whispers on the Apple Discussions forums point towards a new update that will roll out pretty soon – hopefully this will be the final one that nails the flickering issue right on the head instead of a botched job which was released a month ago. Apparently, said rumor points to a 3-week release time frame, which could be tied down to the delayed iMac shipping time that we reported last week. An Apple representative debunked that speculation, claiming that the 3-week delay was due to Apple having issues meeting with demand for the new system since selected components are in limited availability. How convenient, don’t you think?
