Apple Releases Firmware Update to Address Screen Flickering on 27-Inch iMacs

Apple today released 27-inch iMac Graphics Firmware Update 1.0, addressing recent complaints of screen flickering on the company's newest iMac models.

About 27-inch iMac Graphics Firmware Update 1.0
Updates the graphics firmware on ATI Radeon HD 4670 and 4850 graphics cards to address issues that may cause image corruption or display flickering.

Installation instructions for the firmware update, which weighs in at 683 KB and requires Mac OS X 10.6.2, are available in the associated support document for the release.

Apple's new 27-inch iMac models have been plagued with reports of issues since their launch beginning in late October. Early reports of Flash performance issues were fixed with the release of Mac OS X 10.6.2, but more recent reports have revealed machines being delivered in a non-functional state or with cracked screens.

I first noticed the flickering this morning when I woke, a quick reboot later and it seems to have disappeared…

That said this update is welcome, if only it could also remove the speck of dust under the glass...

If only the flickering happened behind an anti-glare screen. . . .

This will usually result in more dust under there when you put it back, unless you do it in a closed environnement that is completely dustless, such as a government secret research laboratory under the Nevada desert.

I very much doubt anyone has access to those except few key government employees.

Tell me about it. I just arranged for iMac #3 to be delivered to me yesterday. All because of the yellow tint at the bottom of the screen. Ugh.

now fix the flickering + snow/noise + screen scrambling with your 30-inch display via the $99 mini-displayport to dual-link dvi adapter!
