I created a Facebook group. Had enough of it really. A friend of mine received his iMac 27" today and guess what: "Screen flickering, yellow tinge which is really annoying, a high pitch screen noise whenever he lowers the brightness on his computer AND a noisy hard drive. I've had it with this. I have no idea whether this might help but it is, in my opinion after 3 months of waiting, time that Apple does something about these matters and gives it's community some official news. No better way to reach the world than with a Facebookgroup. Url: http://www.facebook.com/group.php?gid=242260655059 Name: knock knock Apple - iMac 27" issues - News?!
