    I share your view on this matter. I think Apple is strategically silent with festivities like Christmas / santaclaus around the corner. The new iMac is delayed until 2013. If they acknowledge a serious issue on the MM ,they admit not having affordable and 100% working desktop computers available for sale in the holiday season. A sales managers nightmare.


    I'm in the process of refunding my MM and build an intel/windows machine. I used macs as my primary desktop since 1991, this year I switch to windows for primary workstation. ( I do like win7 already, and win 8 looks promising but isn't there yet).

    Thunderbolt(from mac mini) to hdmi or vga (to monitor) have the same problem with snow/black screen???Anybody tried it??

    I think OSX Intel HD4000 driver for HDMI is really Bad, on windows works fine. (tried on 2 samsung LED displays)



    HDMI - HDMI (colors are burned , too white and bright)

    TB - HDMI (colors are burned , too white and bright)



    HDMI-DVI (not tried since I do not have a monitor with DVI, others report that this works fine)

    TB-VGA (works good normal colors)


    GOOD(Windows 7 on mac mini late 2012):


    TB - HDMI

    HDMI-DVI (not tried since I do not have a monitor with DVI, others report that this works fine)



    APPLE NEEDS TO UPDATE INTEL HD4000 driver/firmware , I think. since in windows works fine I think is a software issue.

    Ok, I can now confirm: running with only one memory module does NOT help against blackouts. I've tried it with either memory slot. Still get occasional blackouts.

    I have this problem on my Mac Mini purchased 12 November 2012 (Sydney, Australia - Hornsby Apple Store).  I was getting a black screen for a few seconds before rectifying itself, but yesterday and today I got the grey snow and had to disconnect/connect the monitor to get the display back.  It typically happens a short time after I start up the computer.


    My setup is HDMI port to HDMI-DVI adapter (supplied with the Mac Mini) to DVI cable (supplied with monitor) to BenQ G2450 monitor.  I'm keeping a VGA cable on the other monitor input for when I connect my work laptop (Lenovo).


    I've just reported the issue to Apple Support and opened a case number.  I have to take the Mac Mini to the Genius bar with the HDMI-DVI adapter for testing (which won't happen until Sunday because firstly I am flat out at work and secondly because I need to get Time Machine up and running first and backup).


    I'm really disappointed.  I don't want to swap the machine as it has taken so long to get everything installed and running on this machine (and I'm switching from a PC, though I have used Macs in the 90's and 2005-2006 for work).  It's my only home computer, so I don't want to part with it.  I'll be pushing for a Thunderbolt to DVI adapter to get around the issue, if possible.


    If they force a replacement machine on me, will I have problems with my Windows 7 license for my Parallels virtual machine?  I had trouble getting hold of a full copy (not upgrade or OEM) and it cost me $$$, not to mention the time setting all this up!

    My friend UrielGarciaC i don t have any problem with the colours!HdMI to hdmi works fine with the colours!But i have black/snow screen!

    I purchased a MiniMac and I am getting the same problem...

    If you haven't already done so, it is important that you log a call to AppleCare. This will protect you and help the rest of us!

    I think we should give Apple a break. I had the same problems with video blinking etc but got contacted by Apple support and a replacement mini shipped within a couple of days. The new machine had exactly the same problems. But I still think we should be patient and wait for a SW (or hardware) fix.


    Here are my reasons:

    - If two units don´t play together it´s hard to put the blame solely on one party. HDMI (with the included HDCP and other signalling) is notoriously complicated. As many know it´s very hard to guarantee compatibility without actually testing the specific combination. This is easily verified by going to any home-theater forum...This is also one of the reasons for the frequent SW-upgrades needed for almost all higher-end TVs and AV-receivers.

    - I am questioning how wide-spread the problem is. My guess is that less than 5% of all mini-buyers have seen the problem.

    - Since we already know that Apple are aware of the problem (since post #18 in this thread) they are definitely working on this. I am not really interested in their progress before they actually have a fix. This work is probably also not helped by the fact that Intel engineering also would be involved in this.


    All-in-all I am pretty positive and I think we will see a solution within a couple of weeks. (But I can also symphatize with customers that bought the mini as their only computer and cannot use it at all...)

  • UrielGarciaC Level 1 (5 points)

    I think also as "wolf 1"  , The HDMI issue bringing all my ideas and tests together, seems to be a Driver issue with HDMI devices,


    It works on some Displays different brands, some other not. In my case I have 2 Samsung displays. None of them works well with colors on HDMI. 1 of them works excellent on VGA the other doesn't.


    On windows my mini works well with HDMI and VGA on both Samsung displays. so I think this issue with HDMI needs a Driver update on OSX. My mini fits all my needs I don't want to return it, But it's annoying that Windows works well on my Apple Mac mini, and my 1st OS (OSX 8) doesn't.


    So maybe we need to give engineers a break so they can think how can handle this Intel HD4000 Driver for OSX improved. But I hope apple at least give us a hand on this. at least tell us, (HDMI is not compatible with all of the HDMI capable displays) use Thunderbolt,DVI or VGA instead. I think answer for this questions is needed.


    I will wait for an update or change my mini for a new one later under the 1 year warranty. I need this machine is awesome not think on returning it back.


    I've read over the web about color etc. And my first approach to a conclusion on this issues. is that minis force to send YUV colors on some displays. and the range of colors are nos interpreted well. some monitors allows you to change it to RGB. I'm not an expert with this but I think it has something regarding this.

    I disagree. Apple at least needs to make an official statement saying the problem is being investigated. Heresay from some tech is not sufficient.


    • Why is it that a cheap DVD or Blu-ray player and various DVRs talk to my devices, TV or monitors, without a problem?
    • Why can the Apple TV 1 and 2 both work without a problem?
    • Why can various Apple computers, G4, G5, Intel MacBooks and MacBook Pro work without a problem?
    • Why can various PCs I've connected work without a problem?
    • Why can the Thunderbolt port work without a problem (except in my case where it died)?


    This problem appears to be widespread with many different brands of TVs and monitors, straight-through HDMI, HDMI to DVI, and even monitors without HDCP. The PC forums mentioned here are also talkng about it. I'm not buying it that Apple wasn't aware of the problem. They may have underestimated how many customers would be affected.


    Note that many Apple customers don't know of this forum. Other customers don't use the computer often enough to see the issue. Others won't realize that it's not acceptable for this to happen. Others will run the computer headless leaving the issue for a subsequent buyer. Many people just don't bother reporting problems because they assume someone else already has.


    I don't know what the statistics are for how many people report a problem and how that translates into the actual number of problems. Is it 10 to 1? 100 to 1? 1000 to 1?


    It's not that the mini has a problem that's the issue. It's Apple's continued lack of acknowledgement that is a disservice to their customers.

    I agree!


    When Canon released their EOS 5D Mark III it was found that the top panel LCD backlight if used when taking long exposures would alter the exposure value possibly resulting in an underexposed image.


    Canon immediately made an announcement and stopped shipment of the camera until a fix for the problem had been found!


    My Mac mini cost just under £1,000 my EOS 5D Mark III cost just under £3,000 I think Canon get my vote at customer relations!

    anyone installed the OS X Mountain Lion 10.8.2 Supplemental Update 2.0? does it fix the problem or is it only for the keychain problem?

    I do not think so. I think Apple charges premium for their devices and it should give us at leaset an explanation or acknowledgment of this issue.

    I have 3 displays and several devices that work with those displays. Apple mini 2012 does not.

  • mark.augustin Level 1 (0 points)

    After months of thinking about whether I should buy a new mini or have a go at putting together a hackintosh I was all ready to place my order today.  Then I ran into these discussions and I am so glad I did.  No way I'm buying a mini now.  -1 for Apple.  Boo, hiss.
