    So far it has behaved itself, I did think I saw one or two very short blackouts the other morning but I think it was actually 'Console' updating its window. When I am just running Safari and Mail I have Activity Monitor and Console on my second screen connected via HDMI to DVI, just so there is something there. Otherwise I would have windows associated with either Photoshop or Audition on the second screen.

     

    There have been no instances of the shash / snow like interference as yet.

     

    At this moment in time I would say I am happy with the setup as there have so far been no blackouts or any other display problems.

     

    I don't know if the one I have has anything different about it?

     

    While typing this on my MBP I have CCC cloning the HD to an external USB3 drive and all has been well.

     

    Slightly off topic, the USB3 hard drive I am cloning to is the Hitachi Touro and it is fair zipping along, 26 minutes in and 95.75GB copied!

     

    My dilemma, as I think I mentioned before, is if it continues in this fashion and an update is brought out to 'fix' the blackout problem do I dare apply it?

     

    At this moment of time I would have to say its a keeper!

    Thanks Philip!  Sounds promising.

     

    Has anyone at Apple asked you for a status update, or have you sent them any info/detail on it's behavior since the replacement?

     

    If Apple haven't asked for any update info from you, then the logical inference would be that they were confident with the fix, whereas if Apple asked for an update from you then they were not confident and that they were experimenting with a fix.

     

    I will wait a week to ask you for a similar status update if I may impose.

     

    I'm really interested in buying the Mini - its price point and hardware package suits me ideally but this video issue is worrisome. I'm new to Macs (always a Windiws user) but this issue gave me pause. So I haven't bought it yet.

     

    Thanks again!!

    For what it's worth, the blinking in no way affects the computer itself. I've typed through the brief blackness and it's all there when the monitor blinks back to life. I'm a recent Mac convert. I love my wireless keyboard, trackpad, ad Magic Mouse and wonder what took me so long. Tho issue resolved, it'll be a great piece of hardware.

    I am due to report on how the MM is working, they will contact me after the weekend.

     

    Still going strong!

     

    I should have made a note of the last MM details to see if this new one has anything different.

     

    If you want to contact me in a week that will be fine

    After returning my 2012 mac mini a couple weeks ago for the blink/snow issues, i ordered another custom build i7 2012 mac mini connected via HDMI to Sceptre TV.  I plugged my shiny new mini in and waited for it to boot up, made it to the welcome screen and blinky blink snow.... back in the box, off to the apple store for a refund. 

     

    Will order another one in a week or two unless I get fed up enough to buy a PC instead... or maybe a build a hackintosh.  I really just want a working mac mini though... I know that's probably asking to much...  it'd be really great if apple would decide to let us know what's going on and that hopefully it'll be corractable via software so we could stop guessing.

     

    Hopefully some company will release a thunderbolt video card for the mac (at a reasonable price)... then I can have my mini & dedicated gpu.  Apparently some have already have this up & running in windows/thunderbolt so there's hope (at least via boot camp if not MacOS).

    It's highly doubtful that anything different will happen for the next 30-60 days. It will take that long for the developers to test the newly seeded 10.8.3.

    That would indeed be great, or maybe Apple could release a Mac mini Pro with dedicated GPU and some other goodies.

    Yes, 10.8.3 will probably takes some time however a separate firmware update could be provided prior to that.  There's also the possibility that something could change hardware wise as some have reported no issues when they replaced their mini.  Either way, Apple offers free shipping and a 14 day no hasstle return policy (at least in the states) so I have little to loose and everything to gain.

    MAC MINI 2012 Hey there, I changed the refresh rate in mac display settings and this has fixed the problem, on 60hz NTSC I had some blackouts, on 50hz I have had no issues.

    experiment with your refrersh rate.

    Interesting little article on refresh rates:

     

    http://reviews.cnet.com/8301-33199_7-57524894-221/what-is-refresh-rate/

     

    For me, I'm not taking a step backwards to MAKE IT WORK.  I'm not going back to a 50hz refresh rate. And I'm not taking one stick of RAM out.   Let Apple/Intel fix this product properly.

     

    If I do anything to circumvent the HDMI, I'd go with this as a stop-gap measure:

    Yap, fair enough.. I hope it resolves, as the Mac mini 2012 is awesome, much better than the new iMac for me.

    I was running: terminal, safari, mail, itunes, steam, preview, xcode, itunes simulator, activity monitor.  today for the first time my screen went black for 3 seconds and then the screen went to static and wouldn't stop.  I unplugged and plugged back in the HDMI and it worked.

     

    I've had 2 second black screen issues every once in a while.  Maybe 15 times since owning it.

    Have you tried 50 MHz instead if 60 MHz yet?

    Two things; 1) I took my Mac Mini back to Best Buy, knowing that the replacement probably wouldn't work, but still, just to add to the pile of returns. And 2) I don't have a 50HZ option on my new Mac Mini, not sure if it was an option on the other one I just returned, either.

    I am in Australia and the option on my display refresh rate within mac os gave me two options 60hz NTSC or 50 hz PAL,  my display is a BENQ GW2450, maybe it depends on the type of monitor you have? I am not too savy about this. All I know is that it solved my problem, I know this is not perfect but it works and I know that Apple should make it foolproof with any type of HZ, but  the mac mini embraces the world of third party monitors and periphrals so it is more difficult to pinpoint, but we all love macs because they 'just work' so I dunno exactly.

    Also I made sure all my connections within my monitor and mac were all set to proper HDMI inputs, this can create snow if you do not set your monitor inputs corrrectly.
