Yep I just installed it about 15 minutes ago. I updated iTunes and then the iMac update popped up when Software Update checked again. Hope this fixes my minor screen flickering!

...from Apple software updates. Just downloaded and installed it. There's no accompanying explanation as to what the update does, in terms of technicalities.

Get it while it is hot! :D
And for those who received it? is it worth the download? lol

I hope this helps people with flickering displays.

It's strange, I have yet to apply the last firmware fix since I wasn't experiencing any problems so that is listed in Software Update as:

27-inch iMac Graphics Firmware Update Version 1.0


Then, the new one just released under that is:

27-inch iMac Display Update Version 1.0


So the new one appears to be a firmware update for the panel itself.

Hmmm. You seem to have resisted bumping the memory in your I7 to eight gigs...I have, too, even though doing so is only $100. The few benchmarks I have seen don't seem to show a substantial improvement in much of anything.

This means Apple is accelerating the solutions to the problems (flickering and yellowing), and I am happy with it cause I am holding to order one through the AppleOnline (I am waiting for more than 2 months in a reseller) until some definitive solution is held, especially for the yellowing, which I hope will be in 2\3 weeks, as Apple said it that internal memo.

So, let the reviews begin and say wether this firmware update has really stopped flickering!

Yeah, I do plan to do so eventually but like you I've seen the benchmarks and don't feel the burning need to go out and do so right away. The 2 slots are empty and waiting for whenever I want to take the plunge. :)

So now I'm waiting for the guinea pigs to report back on the new display firmware. I really hope this fixes the flickering for those suffering with it.

Interesting to note, my newly received Week 05 iMac does not need this update, so they must have had it rock 'n rolling for a while

Should I apply the update?

I have a week 50 iMac (27' i7) and it is running beautifully with no flickering or yellowing. Should I risk upsetting the delicate balance of things and apply this update?

Thanks for the advice.

I assume software update would show this if I needed it? I got my replacement 27" i7 today and software update it not showing needing any firmware updates.

Is there anyone out there who had problems and downloaded this?

What happened?

As mentioned above, if this update is not appearing in Software Update for you then your iMac shipped with it already applied.

As for whether or not you should install the updates on a machine that is not experiencing any issues that is entirely up to the user to decide.

Being in that situation, I have yet to run either update. I am reading some initial hopeful reports on Apple's own discussion forums from some users with flickering that thus far have not had any problems after applying this latest update. We'll see as more reports continue to come in.

So I finally decided to go ahead and run both firmware updates on my week 47 i7 in spite of the fact that I wasn't experiencing any issues.

As others have reported, I see absolutely no difference at all post-update to pre-update: no problems before and no problems after. There is absolutely no difference in the quality of the display (color uniformity, etc) either, not that I was expecting one.
 

Peace

I would and did. It's a firmware update for the graphics card.

Mine seems the same. I have the i7 and I've never had any problems with it and still don't.

my i7 was well bahaved for the first 3 weeks of ownership.

it then developed some intermittent flicker/glitching that, if let run long enough, would manifest itself as a full 25% downward shift in video (the dock would be about 25% from the top of the screen) until reboot.

that's when i applied the first firmware update and since then only had an occasional flicker.

i just applied the new update. i'll let you know how it goes in a week or so. :D

Yeah, the yellowing problem has been solved. Apple already sent me my blue-tinged glasses.

I have a week 2 I7 and it ran just fine for 4 days and then today, Flicker and short burst black screen.

I installed the latest upgrade and have not seen a glitch since. Here 's hoping.

works for me!

the graphics firmware update didn't fix my flickering.

this new display firmware update has! it's been an hour and i've had no flickering so far, normally i'd see it within 5 minutes after it's booted.
