    There was just an article finally on 9to5 mac and macrumors addressing the issue. Looks like there will be a fix in the future. The 10.8.3 update does contain graphic drivers, but doubt this issue will be included in it. Unless Apple sticks a fix in there before release because 8.3 has already been seeded to developers. Least there is an answer out there that this infact is being worked on by Intel and a fix will be released. I assume that is also meaning it can be addressed with software.

    Here are the details from my Mac

     

    Chipset Model: Intel HD Graphics 4000

    Type:  GPU

    Bus:  Built in

    VRAM:  768MB

    Vendor:  Intel (0x8086)

    Device ID:  0x0166

    Revision ID:  0x0009

     

    For the MAC itself

    Boot ROM Version:  MM61.0106.800

    SMC Version (system):  2.8f0

     

    Is this any different to your machine?  Still no flickering screens to report so it certainly appears to be fixed by replacing the motherboard.

    Hi Adam, looking at the display the VRAM total is different at 768 MB and the SMC is a different version

     

    This maybe a totally different gpu but same chipset

     

     

    Boot ROM Version:          MM61.0106.B00

      SMC Version (system):          2.7f0

    Yesterday I got a black screen using the Mini display>DVI adapter, and it stayed black until I restarted the computer. I had the flickering with the HDMI>DVI adapter earlier so I switched to the Mini display, and it worked great for a few weeks until yesterday. I cannot rule out it's a bad adapter, but it could be interesting to hear if anyone else has similar experience with the MD>DVI adapter.

    Hi mfearby,

     

    That information is found in the Harware Overview section of system information.

     

    Cheers

    @ jcmcalvin, Mine also ran for hours not having any problems. It's occurring very random. Now mine at the moment is connected with the minidisplay to dvi and working good for the past two hours. The first 4 days there was no instance once whatsoever.

     

    Here's the sysinfo of my macmini:

     

    In Dutch:

     

    Fabrikant:     Intel (0x8086)

    Apparaatcode:     0x0166

    Revisiecode:     0x0009

     

    Opstart-ROM-versie:     MM61.0106.B00

    SMC-versie (systeem):     2.7f0

     

    All the same except for the SMC version.

     

    Hey and onother person with the same issue via minidisplay to dvi adapter. It looks like it has nothing to do with the way you connect it and everything to do with the igp.

    I wish I could have kept the i7 quad core but this is getting ridiculous. Now people are reporting both HDMI and DVI getting the same problem.

     

    Waiting for a fix is just way too risky if you've got the chance to get your money back. You could always hold on to the cash until this blows over and then buy one again. Of course this is only good if you have another machine to work on while you wait!

     

    I have a bad feeling it's the HD4000 itself, not a firmware/software update but a return computer to shop job. I hope not for other peoples sake but I couldn't take that risk.

     

    Sam.

    I have the 2.3GHz quad-core Intel Core i7 with 16Gb of Crucial Ram (Problem seen before the RAM added).

     

    My machine's details are identical to yours. I received it as a replacement on 13th Nov. the HDMI output (HDMI to HDMI and HDMI to DVI) has the problem but TB to DVI is working fine.

     

    I hope this helps.

    I really appreciate your help, but we shouldn't be grovelling around reading third-party sites, all of whom seem to be feeding from one announcement - not from Apple.

     

    In this world we all at one time or another foul-up. What sets us apart, having fouled-up, is what we do about it. Apple has a large and devoted following, many of whom contribute to this thread. I am not in that number, I am brand new to Apple, I bought a mini and a Macbook Air on the same day on the back of what now appears to be a misplaced reputation.

     

    It doesn't matter how good Apple have been in the past, it is only how they act now and in the future that is of relevance to people currently using Apple products. I believe that we can say with confidence that corporate Apple, excluding some individuals in various locations, know that the Mini has a fault, yet it is still on sale. It is one thing to accidentally sell a product that has a fault that one isn't aware of but quite another to sell products known to be faulty. In the UK The Trading Standards Institute would have a view on that!

     

    I have just 'bought' a mini on the Apple site and was taken straight through to the payment site before I quit. OK to be charitable, the ones on sale may have a different spec and not have the fault. However, if that is the case then surely Apple's first duty it is to its existing customers, not new ones.

     

    This company has had long-enough to tell us how it values us and what it is going to do to repay our patience. We all have better things to do with our lives than waste hours trying to get a very expensive product to work. In nineteen years of using PCs I have not experienced a problem like this.

    I agree, BobH47.

     

    This is not the Apple that …

     

    • … replaced my old CRT iMac because I got a lemon.
    • … replaced my wife's Newton Message Pad 2000 for $145 when she ran over it with the car.
    • … replaced my daughter's iPhone 3GS due to water damage when it was 48 days past warranty.
    • … replaced my daughter's failing MacBook Pro battery without question.
    • … sold the company I worked at hundreds of Macs that 'just worked' 24x7 for years.

     

    This is the Apple that …

     

    • only replaced my PowerBook G3 (Lombard) CPU daughter card because it wouldn't run OS X when I told them I knew about their hidden warranty.
    • tried to charge me $500 when my daughter's MacBook Pro motherboard died after an extended session of running at 100% CPU even though adequate airflow was provided at all times.

     

    I've purchased several iPods, a couple iPhones, and a couple iPads without problem. I'm a good Apple customer. My experience with Apple has been overrall postive, which is why I bought the Mac mini the day it was released thinking this is just a revision of an old product. I will never make that mistake again.

     

    Yes, every company makes mistakes. A good company apologizes, takes ownership of the problem, and makes it right. So far, Apple has done none of those three things and they've had enough time to do the first two while we wait for the resolution and for them to make it right.

     

    Given the countless hours people have expended trying to troubleshoot this problem that only Apple/Intel can fix, they should give everyone who bought a mini a $100 gift certificate.

     

    But to continue to sell the mini from the time they identified the problem internally makes this a débâcle. They are knowingly selling a defective product. This is not the Apple that revels at being at the top of customer satisfaction surveys.

    Thank you Adam Currently I don't see any real changes from what others are reporting.

     

    I'm assuming you have Model Identifier: Macmini 6,2?

    Dear Tom,

     

    I'm glad its not just me. You have clearly had brilliant customer service in the past. What a pity it is that your experiences have changed.

     

    I hope these gift certificates come in sterling and many other currencies as well! It's a nice idea but I won't hold my breath.......

     

    Bob
