Apple offers fix for iMac's Radeon HD 4850 freezing issues

post #1 of 81
Thread Starter 
A rare weekend software update promises to cure system freezing issues in early 2009 iMacs equipped with an ATI Radeon HD 4850 graphics chipset.

Released on Saturday, iMac EFI Firmware Update 1.4 (1.7MB) specifically addresses the hard lock-ups that occur at random and leave iMac users with the custom-order graphics with no choice but to reboot their systems to regain a usable computer, regardless of whether they're using Mac OS X or running Windows in Boot Camp.

It also mends problems owners have encountered which prevent the systems from waking properly from sleep when using Boot Camp, Apple says. The update requires Mac OS X 10.5.6 or later.

The company hasn't explained what has caused the problems, which have triggered lengthy discussions on Apple's support forums and, though producing different symptoms, have drawn parallels with an earlier ATI graphics freezing issue from 2007.

I can barely work.

This is a normal occurance in the industry. DELL Inspirons and Latitudes we had constantly crashed for months before they finally rectified the issue with firmware and driver issues. Sometimes things slip through quality control and this was one that caused users and Apple support much headache.

Just got my new 4870 from Apple for my early 2008 MacPro. Aperture won't run. Says the card doesn't meet the min. requirements. Huh?? WTF?

Slip quality control?

Have you seen the LCDs in the iMacs?

From the 20" to the 24" - they are worse than last year.

The ones made in January have a yellowish tinge.
The ones made in Feb/March have a blueish tinge.
The ones made in April have both issues in one panel...

The backlighting on the iMacs are just horrible.

Dust under the iMac glass too... Gotta love the Apple quality control!

mac os x 10.5.7 has all the drivers for the card. the card really wont work until you update to 10.5.7
post #12 of 81
Makes you wonder what exactly was causing the problem. Being an EFI update they could be adjusting any number of chips. So I hope this does not impact performance.

Not that Ive got an iMac, rather a MacBook Pro. Even that could use some driver work.
post #13 of 81
Has anyone tried this yet? It is appearing in my software update but I am extremely reluctant to install. Last time I installed a firmware fix for graphics issues was my 2008 Mac Pro, and it made the fans permanently louder from then on.

True. My HP laptop was occasionally dropping wireless and only reboot would bring it up again. Other people were complaining about the same issue on this specific notebook.

Not a big deal as it would happen up to twice a month (in my case), and would not freeze/crash system, so I was able to save whatever I'm working at and reboot... but still.

Half a year after notebook was released (and some 4 months after I have purchased it), new drivers were released by Intel and that sorted problem.

But... beside being one of the first HP notebooks based on new Montevina platform, my notebook was also $700 one.

Maybe it's only me, but for premium product with premium price, I'd expect better testing and quality control... \

Apple has been calling, or sending e-mails to people who received the boards. They say that the boards were sent out too soon, and that the software wasn't yet ready.

I suggest that you wait a few days, and check:

Over the next few days, to see how others have fared with this.

And this is the main reason I won't spend the money on Apple's "premium" (I meant designer though) computers anymore. When we pay as much as we do, we expect it to work decently well.

They used to have good QC, what happened? I've noticed a big change when we went to intel, but I don't know how much of that is really it.

Bullshit patrol alert!!!

Apple still has, by far, the best QC in terms of customer opinions, support request and return rates. To judge them based on anecdotal evidence and opinions posted in support forums is nonsense.

Besides, my 24" iMac has a flawless LCD with no issues whatsoever...people should stop presuming that their problems are everyone else's problems...issues will ALWAYS happen even if you buy the most expensive article from the most renowned maker. This does NOT necessarily mean they are any worse than before, unless you REALLY show objective statistics to back that up.

Let me ask you a question.

Why do you bother to even use a Mac and admit to owning them?

Just use an affordable Windows-based PC and problem solved. Just switch.

All you do is troll and complain about Macs.

Yet, this is in your sig:

iMac 20" 2.66 2008/9 model
Nano 3rd/4th gen
iPhone 2G/3G


If you CLEARLY dislike Apple and Macs so much, then . . . WHY DO YOU EVEN OWN THESE PRODUCTS? Just sell them. No more worries, no more stress.

It seems pretty stupid of you to have them in your possession and constantly troll about them. Does it make sense to hang on to, and discuss something you dislike that much? There is an ocean of PCs out there for you to pick and choose from, and they have nothing to do with Macs, and they run Windows.

The result:

No need for you to come in here and complain, which means no more headaches on your part. You'll be a satisfied user, which you cearly are not. The only kind of person who keeps using something they dislike and who then takes the time and trouble to complain about it is someone who is mentally ill.

Fair?

Why? I love the OS system and got lots of software for it.

Apple has to improve on the hardware aspect. They have gone backwards IMO!


I will continue to complain as freedom of expression until something is done (I have voiced my opinion to Apple and they are well aware of it)

In the end you will get a quality product at premium price because of ME

It is because Apple is getting bigger and most of there products are made in China.

I noticed that the iMacs with the serial number starting with "W" have more issues than "YM" or "QP"

I don't mind paying a premium price for something, as long as it's a PREMIUM product.

If not, you will hear me complain until they justify the price.

This iMac has been the same design since 2007 through 2009 and the same issues with the LCD appear only worse. Does it take 2+ years for Apple to make the changes? I thought for sure with a new product launch in March they would fix the LCD but they didn't. Beats me!

...someone certainly has a high opinion of themselves!! I understand the whole love of the OS and investment in software. I think what some of the users are stating is that you seem to have a had a lot of problems with Apple products and combined with your posts, you come off like most of the people that were having the red ring of death problems with their Xbox 360s. There were people stating that they were on their fifth or tenth (for example) 360!! I'm sorry, but if I can't get a satisfactory product by the third time around, then maybe I should consider other options. Apple is no exception to this. I have had VERY little in the way of problems in the sixteen years I have owned Apple hardware, so I am good with that. In your case, it sounds like you need to explore some other options since Apple seems to be causing you so much grief though. Just something to consider. Some companies tend to notice problems more when people just stop using their product. It is a known fact in the retail world.

Or it could be the shift to making it cheaper but still charging the premium price in hopes that no one would complain?

So because Apple has a fan base, they think they could get away with it and people will just use it because they want it.... Not so the case! I want it and will point out the horrible QC and hopefully Apple will do something about it.

I have an early 2008 MacPro, and recently bought an Apple Cinema Display 24". Of course, on Apple's advice, I had to upgrade my video card to a 4870, and what a beast it is. The display is brilliant, but iPhoto '09 has problems, VMWare Fusion will not run, the machine will not enter sleep mode, etc., etc. After several conversations with Apple, I am left with the admission they released the card before the software was ready, but they "expect it to be available for download" any day now. One tech told me that 10.5.7 will be out "within two weeks."

Again, Apple should have thought of the 'after sale'

Firstly, Apple should have covered all the bases...

a) Is the current software capable of handling the new hardware? No. Then don't release the hardware.

b) Does the hardware need new drivers? Yes. Then don't release the hardware.

IMO, Apple is doing a fine job in bad PR and making themselves look just as bad as Microsoft.

I've seen this here before, and it's just as much nonsense now as it was then.

Apple, as most all other computer manufacturers, has had their computers made in china for a decade or so. That has nothing to do with anything other than having them cost less than they would have.
Dell, until recently, has made its own computers here, and in Europe. Their quality has never been anything to brag about.

Apple is having no more problems now that in years past. Every time they have some problem I read this about them having more problems than before. And that's going back to the time when their computers were made here.

You have the right to complain, but I suspect that you will always find something to complain about. Some people it seems, just like to complain.

I don't like it when Apple has problems any more than you do, likely less, as I have a fair amount of stock. but I realize that all companies have problems, and that some of it is beyond their control.

I have two 24" iMacs from 2008 here, and neither one has a monitor problem. We have more than a few in the photo labs in my daughters school, as well as 20" models, and their monitors are fine as well. I checked them carefully once this problem became known. But it affected a bunch of models around a certain time, and that's it. It's not as though all of these machines were affected. Apple took care of those who had the problem. Not every manufacturer would have even bothered to do that.

Again, this isn't really true.

Look, all monitor lines from all manufacturers have problems. mostly, people don't even notice them, or care. It often seems that Mac users are much pickier than most PC users, because I've seen plenty od PC monitors with visual problems that people haven't mentioned to me. I don't bother to even tell them about them when I see them, because why worry them with something they don't notice?

I have seen a couple of iMacs with "bad" monitors. But bad by what standard? Almost all monitors have a certain amount of off color, or unevenness in backlighting. How much it too much? If you have to look for the problem in order to find it, then it's likely not too much. I know people who don't see problems in products until they read about them. Then they notice it. It that REALLY a problem? Likely not.
post #31 of 81
Yes people pose the assumption that Apple didn't have many problems before. Now they have more than ever, this isn't true at all. When dealing with consumer electronics problems happen.I think people just like to jump on Apple more than anyone else about it.

How could you have sampled a large enough selection of iMac's to observe serial numbers starting with W have more issues than serial numbers with YM or QP? I don't believe you could possibly have. If you did, you sir have absolutely waaaaay too much time on your hands.

Considering the office bought 10 units all having different serial numbers, I noticed a difference between them. Some units have a yellowish or blueish tinge on either side. So that is how I know

That's par for the course with monitors. They all produce slightly different images. You could have a group of monitors that cost $10,000 each, if you look hard enough they will all have some type of difference in the way they produce color or contrast. Its pretty much impossible for two monitors to produce the exact same image.

As Mel said earlier it comes down the differences being close enough to not make much difference or being too different to be usable.

Did you attempt to recalibrate the color profiles to bring the white point more into white? You can freely adjust the gama in system preferences.

It takes time to do things right.

Unless you're sole interest is in more things to complain about, the which seems more and more likely as time passes.

As one who recently bought a 24" iMac and 24" LED Cinema display, I would argue that his complaints are without solid basis.

But then, I don't buy computer equipment to b1tch about it here.

As others have said, calibrate the monitor.

I hate to think that I have to tell you this, but EVERY monitor you buy, other than high end professional graphics monitors is "bluish" from the factory, and don't try to say otherwise, because if you do, it will only show that you really don't know what you're talking about.

Manufacturers, from computer monitor manufacturers, to Tv manufacturers, set their monitors at a high color temp. (usually around 9,300 k) and high contrast, with higher saturation.

Why?

Because the average customer doesn't know any better, and likes brighter screens, which setting it bluer allows, as well as high contrast and saturation, so the image will "pop".

Is this good? No it's not. Does that matter? Nope! They do it anyway.

Computer monitor manufacturers, Apple included, do less damage on the high saturation and contrast front that do Tv manufacturers.

But it's a simple engineering problem that setting a monitor to 6,500 D, or esp. 5,000 D brings down the possible brightness. As most people work in bright rooms, they want brighter monitors.

In fact, very few monitors can even be calibrated to the 5,000 D standard, which is why the industry settled on 6,500 D.

But it's a simple engineering problem that setting a monitor to 6,500 D, or esp. 5,000 D brings down the possible brightness. As most people work in bright rooms, they want brighter monitors.

In fact, very few monitors can even be calibrated to the 5,000 D standard, which is why the industry settled on 6,500 D.

I did with Huey Pro and and it sucked more.
