    Hello all,

     

    i tried alt-cmd-p-pr reset, different memory configuration in both slots, resolutions, different cables and everything. Nothing helped. Called AppleCare to register my problematic Mac mini as well.

     

    While in the queue, i realized that the mini-displayport-to-DVI adapter (which i used with late 2009 macbook pro before) fits the thunderbolt slot (I did not know that). With that plus a standard DVI-to-HDMI adapter I connected the computer to the same HDMI cable and disapointingly saw the screen blink twice (thinking it continued flickering...)

     

    BUT WAIT! Now already 30 minutes without a single flicker. Which is a LONG time with the frequency the HDMI port did it (see post below). So it seems it flickers twice to "initiate the connection"???

     

    Just to verify this I reconnected directly to HDMI: "normal" flickering continued as before (every 3-10 seconds).

    Connected again Thunderbolt-DVI-HDMI; works well after two initial blinks.

     

    But still annoying bug, which should be fixed. I'll keep you posted if flickering really stays away with this configuration.

     

    And where's 10.8.2???

    Here too, bought the day before yesterday a Mac mini (2.3 GHz Quad-Core Intel Core i7).

     

    Screen goes black every 3-10 seconds for a very short period. This does not seem to interupt any ongoing process/operation, e.g. movie is playing during the "blackout" and audio outputs normally from optical miniplug to AV receiver.

     

    Extremely annoying, and I haven't found any definite fixes. Somebody talked about some resets with HDMI disconnected. How can I see how to reset anything with my only monitor (HDMI connection to Sony Bravia) is disconnected?

     

    Any fix, Apple?

    Have the same problem here. I have a two monitor setup. And the one connected to the HDMI to DVI Apple supplied cable either flickers or goes to white static. It's a annoying as ****. My quick and dirty fix is to pull out the HDMI cable of the Mini and connect again quickly. But it still annoys me alot. 

     

    And somewhere - in this post I believe - it was stated that you could try re-installing the latest update (10.8.2). But that's a no go. The package installer simply states that none of my drives meets the requirements.

     

    Hope Apple will address this soon.

    So.  I too, was contacted by an Apple support person asked to expidite my exhchange so they could capture my faulty Mini @ the store where I bought it.  After an hour on hold this morning waitning to contact the manager at the store to facilitate the exchange, I watied another thirty minutes @ the store - who were completely clueless, despite calling ahead of time to expedite the exchange.  I get my new Mini, finally...

     

    Only to find out that the Mac Mini I just exchanged has the exact same problem.  Blinks out about once an hour.  Snow // glitching too.  The same exact thing.

     

    This after after two days setting up the original Mini for recording, and a day deauthorizing everytinng.  Now I am faced with...  what?   My living depends on my computer - small recording // production studio, though very busy.  It's a non-trivial thing to have to download and reinstall umpteen gigabytes of music software.  It literally takes two days.

     

    I've been on Apple computers since the ][e.  Loved them.  But I've had nothing but clueless technical support, bad customer service (truly horrible) and no help from anybody at Apple.  None.  My problem is, I'm stuck.  I'm a professional, depending on Apple to be "pro" both with their hardware and their software.  I don't know, maybe I need to speak with somebody at executive relations or something.  I'm now completely w/out a solution here.

    Apple is using their customers to do QA for them.  This should have been done before the product was released.  With such a pervasive problem it would be hard to believe they didn't know about it prior to release.  IMHO not a very classy way to act Apple; especially when you charge a premium for your products.  Somwhere there is one or more eemployees that ought to be ashamed of themselves.  I wonder if any of them are named Scott F?

  • McBRiDE Level 1 Level 1 (0 points)

    I've had the same problem. I have a 2 monitor set up and the one connected through the HDMI port gets the flickering. Took it to an Apple store who told me to ship it back to get an exchange. Just got the new one today and within an hour I had my first flicker. Phoning apple care tomorrow morning.

     

    It's really ruined the excitement I had at getting a new mac. Now after reading that others have the same issue and there isn't a fix, I'm really regretting buying it.

    so the conclusion ?

    dont buy mac mini 2012 yet ???              

  • himalaya31 Level 1 Level 1 (0 points)

    I would definitely buy it again. It´s a great machine but it has this error wating to be fixed.

  • gooch99 Level 1 Level 1 (0 points)

    there is a real issue with the mac mini (late 2012) and Apple have confirmed to me they are aware of the problem and workinf 24/7 to rectify. They appear to have no intention of posting this information, or are they saying at this stage whether there may be a fix (firmware or hardware), although if the later it will require those that have the problematic units returning for repair.  I decided to return my mac mini as I did not like the idea of having to return at a later date for a hardware re build.

    I am thinking of buying a Mac Mini so I have been following this thread closely.

     

    I know the HDMI protocol has several versions, could these problems be caused by using a HDMI cable that is certified for a version below the one of the HDMI port in the new Mac Mini? Like say using a 1.3 certified HDMI cable on a computer with a 1.4b HDMI port.

     

    I am saying this because it seems the TB port works without any issues so that in my mind rules out a hardware problem.

     

    Cheers.

    Dear all

     

    I have written some pages earlier, that my new MacMini seems to be doing fine.

     

    BUT: It started some new phenomenon, it randomly crashes, totally and completely doing a restart on it's own and then presenting an error log (which I always sent to Apple).

    The crashes always happened after some weird "clicking" noises coming from the back of my Mini.

     

    In the log it says something about "Kernel panic" etc.

     

    Weird things I noticed:

    It says I have a MacMini 6.1, but the new ones are 6.2, or am I wrong?

    Also it says, that 768MB RAM are allocated to the Intel4000, before it was 512MB!?

     

    Did the new software allocate this? And why? No one at Apple Support was able to answer...

    Also no one knew about 6.1 or 6.2 Mini, only that, from the specs (Intel4000, i5 etc.) it can only be the late 2012 version.

     

    Totally confused, more angry then ever, facing yet another return or whatever, with data migration, reinstallation, configuring, testing...nad maybe a machine without failure...no one knows!

     

    Could some others maybe check if they have a 6.1 or 6.2? And how much RAM is allocated to their Intel4000?

     

    thanks and good luck to everyone

    No. I used Apple's HDMI->DVI adapter cable that came in the box so unless Apple is supplying a defective cable, this is not the problem.

    That is true for the majority of people. My mini's TB port died while the computer was sleeping within 10 days of receiving the mini. Nothing could get it to recover so I returned the mini and am waiting for Apple to make an announcement on this issue before I repurchase.

    Hello Martin, a note from Mike at xlr8yourmac.com...

    one of the last posts there is from "Martin Naegeli" who is wondered about his late-2012 "mini 6,1" ID thinking it should be 6.2

    - mini 6,2 is the server model, 6,1 is the non-server model (both are late 2012)

     

    Also he asked about HD4000 768MB vram (vs 512MB) - as I mentioned on my page here on video problems, w/16GB ram HD4000 is reported as 768MB, - 512MB with 4GB. (never had 8GB ram installed to see what that showed)

    I'll be buying a new mini soon. I know this may not be popular to say on a thread like this, but as a tech I am not convicted that this is a Mac mini issue per se. These same exact symptoms happen on all HDMI equipment, and the problem is rarely main hardware related, although I can certainly understand why a non-technical person would blame their mini. I know that Apple is already looking into the issue.

    Well then I am the luckiest guy on the planet. When I think of the number of hours I've sat in front of all kinds of HDMI TVs connected with numerous brands and qualities of cables and/or HDMI switches to different Blu-ray players, PVRs, set-top boxes, and computers where the combinations are too many to calculate and only when I hooked up my mini did I see a glitch within an hour. I'm going out right now to buy a lottery ticket.

     

    If this was just an unavoidable HDMI compatibility issue then Apple wouldn't be capturing just minis for examination, they would be asking for a customer's complete setup details. And since many of us are using Apple's supplied HDMI->DVI adaptor, it's still Apple's problem.

     

    The monitors I connected to the mini have been operating for thousands of hours without any glitching while connected to various vintages of Apple computers, so as far as I'm concerned this is a Mac mini problem and I will not be repurchasing a mini until Apple announces a fix.
