Apple releases 2nd potential fix for flickering 27-inch iMacs

post #1 of 38
Thread Starter 
Apple on Monday released a second firmware update that aims to address screen flickering that has plagued some users of the late 2009 model 27-inch iMac.

The update, entitled 27-inch iMac Display Firmware Update 1.0, is a 294KB download available direct from Apple. The accompanying description states the update will "address issues that may cause intermittent display flickering.

The update requires Mac OS X 10.6.2 or later, and applies to all 27-inch models. It comes more than a month after Apple issued the 27-inch iMac Graphics Firmware Update 1.0 in late December.

Monday's update confirms reports from last week, when various posters on the Apple Discussions forums said they were told by AppleCare representatives that a new update to address flickering issues was forthcoming. A week later, it arrived.

Earlier Monday, a new rumor suggested Apple has halted production of new big-screen iMacs as the company looks to address screen flickering issues that have persisted since the new desktop launched last October. Last month, shipments of the 27-inch iMac were pushed back three weeks. Current orders also face a three-week delay.

Publicly, Apple has insisted that the delays are not due to hardware issues. Rather, they say the company has had trouble keeping up with demand for the new system, which was the best-selling desktop in the U.S. in the month of October. In December, the company formally apologized for shipment delays, stating that the hardware has been a "huge hit," and they have struggled to fill orders.

Who in their right mind would buy one at this point? Wait for the next iteration and remember - never, ever buy a first gen Apple product- ever. Hear me iPad salivators?

I couldn't agree more. Your first question was exactly what I was thinking. Only a gluten would buy one of these at this point.

I have always bought first gen and NEVER had a problem, nor has anyone I know. The 27" iMacs in the studio all arrived as ordered and all work beautifully, no issues at all.

If a few million units are made, it is the nature of the beast that a few will be damaged in a transit and a few will be faulty - these things don't like being thrown around warehouses and delivery depots. Let's try and keep things in perspective.

Problems are bad, and I sympathise with everyone who has had an issue.

However, it's a few units, not every unit shipped, not even a significant minority.

So let's keep it in perspective. I imagine that Apple were hard pushed to find one in-house experiencing the same issue(s) and it's taken them a while to discover if there is a common cause, and a common fix. Cracked glass is obviously a delivery issue, the packaging is so minimal now that these things are not getting the protection they need in transit. The flicker issue, they've not isolated and found a fix, the yellowing issue is a seperate issue. I believe the first firmware sent out was meant to help the yellowing, this second fix the flicker. We shall wait and see.

If the number of units affected were only a few, Apple would NOT be considering halting production.

Depends on the cause and the long-term prognosis. If failure rates are trending higher, you want to be careful. Re-tooling to make a change can require a production halt if it is in the wrong spot.

It's more than that. A number of posters on http://discussions.apple.com/thread....04398#11004398 have received as many as 3 faulty machines in a row as replacements.

No, both updates were targeted at the flicker.

I challenge you to go and check how many dead pixels you can find in the iSight camera (best way is to hang the cleaning cloth over the camera). I bet you it's around 10 dead pixels, of various colours, on average.

I consider myself to be in my right mind and I purchased an iMac 27" i7 and received it in November. And I have no regrets about the purchase. Mine has been happily running along 24x7 since I got it with no problems so far. Like anything else you pays your money and you takes your chances. Until Apple releases some solid numbers on sales for the unit you have absolutely no idea how prevalent the problem is. Anyway, I am quite happy with mine.

I am glad, more and more so each day, that I have decided to wait to get my i5.

btw - it's glutton. Gluten is a wheat product used in baking. but then that's me just being picky. no insult intended.

Time for me to be picky; gluten is a protein found in flour that forms when flour is mixed with water. It isn't something you add as an ingredient to bake with.

If Apple actually packed the oversized computers properly there would be no yellowing issues.

And at this point, I'd be less skeptical of Apple if they would just admit the stupid issue instead of saying, "We can't fill orders quick enough."

i'm glad you did it, not me. but it would be nice if all these brilliant poster people also knew how to spell.

also, the french use gluten in their bagels to make up for the lack of certain usa ingredients that can always be found in nyc.

OK, I know this question may make me look like an idiot (not difficult to do, really), but here goes:

I have a 27" iMac that I've had for months, and I've never had a problem with it. I'm still supposed to install this update, right? Or not?

Sorry for the dumb question.

I bought one as soon as it was announced. 2.8 GHz intel Core i7 with 8 GB 1067 MHz DDR3. It was delivered as promised. Never had or noticed flickering or discoloration.
I am totally satisfied with it.
Hear me iPad first buyers. Apple does look after you should anything go wrong.

I received my 27" iMac in the first air shipment of i7's, and have not had problems to date. I am sure there are plenty of stories of frustration and enough display problems to be a concern for Apple, but those people are much more likely to be making noise than those of us who are enjoying a great new Mac.

You should just trust Apple, let the auto updates occur whenever and instal what they wish. If you had an immediate problem, you'd want to prompt it for the update, but you don't so just leave it to sort itself automatically. You trusted Apple to build your wonderful machine, why stop now?

I have an i7, by the way. Perfect. Just took A Zebra's challenge to someone else, I now know I have two dead camera pixels that I wasn't aware of and can't see unless I try hard. Probably the last I'll ever think of it. My wife's 27" Duo is perfect. As are the 2 other's I know of. I reject the extrapolation of observed failures, so must reject my own observation of success rates. But, just as someone saw '3 bad in a row' above, so I'm reporting '4 good in a row' here. Stories of bad machines do gain traction once an individual gets successive failures, but these results are still somewhat skewed since when most of us get a good one, we stop buying!

I don't disagree with Dangermouse. I have compulsively trusted and installed Apple's Updates until this newest Firmware update for the Display. I feel that Apple should first make clear that this is an Update that is appropriate and safe for all] 27in iMac users including the great majority of us who have had perfectly beautiful, flicker-free displays from Day 1!

Ironically, after a good two years of having horrendous problems with Apple equipment, the two i5s that I bought recently are the most reliable setups that I've ever owned.

I've had numerous MacBooks, MacBook Pros, 24" LED Cinema Displays, 30" Cinema Displays and Mac Pros none of which worked as advertised. To give you and idea of the scale of the problems I experienced, I've just finished running through my bookkeeping with my accountant, and in the respective 18 month period I've purchased £20k worth of Apple kit and returned £18k for a full refund. On each occasion, I've received a full refund without question, because whilst Apple will never admit it publicly, the Apple staff know damn fine that there are problems with the products.

So I for one, am absolutely gobsmacked that the two i5s work perfectly!

Apple sold over 10 million Macs last year. If 1% of them had a defect, that's 100,000 defects. If 1 percent of the people with defected units post in the apple discussion forum, that's 1,000 posts in the apple discussion forum, which seems like a lot, but really isn't.

It simply is not possible for us to figure out what percentage of iMacs have this problem from looking in Internet discussion forums and reading rumor sites (not that I have anything agains rumors -- they can be fun, so long as we don't take them too seriously).

One of the frustrating things about Apple is that they are so secretive about these things. But, on the plus side, you will never hear an AppleCare person say "oh, that's not our problem, you have to call the graphics card company about their drivers". Apple will ultimately take responsibility for their products and fix any defects.

Right now I have:

1st Gen 2007 Aluminum iMac, the week they came out. 3 years strong, no problems.

1st Gen iPhone 2007, 4gb model, absolutely no problems, jailbroken and unbroken 100 times.

I could go on with at least 5 other "first gen" Apple products that I "never" should have bought. You don't know what you're talking about, and never have.

Good question. If it shows up automatically, install it. 99% of the time, you'll have no issues with the products or software. This is part of the reason Apple exceeds consumer satisfaction surveys.

You do realize that a discussion board is one of the worst sources to gage an issue right?

Ive read "reputable" journalists use the number of views on Apple's discussion board as the "source" of their in depth reporting as well so its not surprising.

Ive viewed those posts probably 50 times and I dont even own a 27" iMac.

I'm glad you saw the humor in my response and realized I meant no harm. I do some occasional baking and have had to purchase wheat gluten to add to some recipies.

There were bugs with the graphics on the 27" iMac that I have but the second firmware update seems to have fixed it. Even with the bugs this computer is so much better than even the iMacs from this spring. My handbrake ripping went from 16 fps to 90 and WOW framerates are steady over 35 with all the settings turned up. If I had to do this all over again I would.

Sounds like the beginnings of a manufacturing rebellion... major problems at Toyota, then Apple... who's next?

Short of including a link to the story run by AI, I used the word 'considering'. I am in no position to claim any truthiness to the story, I was only claiming that a few bad 27" iMacs would not cause Apple to consider halting production. Dude.

Why is it that Dell sells laptops with exploding batteries and recalls billions, yet nearly no one follows it with religious zeal? Apple introduces a new computer with a problem and the computer world proclaims the end of the world?

I guess everyone puts Apple on a pedestal.

I very much agree with this, even though I got 2 iMacs at work, and both had the flickering issue. 2 I can write off as "very bad luck".

If I got 3 bad ones I would be making a strong statistical argument that this problem is very widespread.

FYI: The firmware update fixed at least one of these iMacs.

Okay, fill me in. I'm on this forum to learn. That's why I joined it. I have learned a lot in the time I've been here. How could improper packaging methods cause the yellowing issue?

My i5 would flicker after about 45 minutes of use. Then another flicker or two, then a dip to black and back. About that time, I would blank the display for a second, bring it back up and the flicker was fixed for another 45 minutes or so.

First firmware update did nothing. But after installing #2 this morning, I worked at my computer for 3 hours or so -- including at least half that time with the display up constantly -- and never the slightest flicker. So, knock on wood, looks good at this point.

I'm ordering a 27 inch imac tomorrow. I'm not too concerned about the flicker. I've had a number of macs and the only problem I ever had was with a powermac 7500. That turned out to be the monitor which was quickly replaced when I returned it to the apple dealer.

many many macs are afflicted by a flickering screen
and some flickerings happen just before sleep some
flickerings happening during dvd play back

some are fixed by software updates
some are fixed by firm ware downloads
some never go away
many buy a new mac
2002 to 2005 lap top mac had the worst time of it

yet flax seeds need to be put in a fridge lest they go rancid
