    Yeah, I did a boot in safe mode- Restarted. Came back once(flicker black to on 1sec).

         Then I tried the SMC reset 2 days ago. Havent seen anything since(fingers Xed). Yesterday I was on it for a good 1-2 hours with no flicker. Other than that issue here everyone is having, I love it! Nice adjustment from just macbooks. Hopefully Apple gets to the bottom of it and lets everyone know what to do.

    I got my Mac Mini on tuesday (30th Nov.) and had no blink/snow effect until 5 days later on Sunday. 


    Now it just happens randomly when I'm watching videos on youtube or vimeo, sometimes nothing will happen.  In my experience this happens when the system/graphics is under stress and I read somewhere this may be caused by HDMI/HDCP handshake.


    Regarding the colour washout problem. I purchased a new monitor about a month ago, a LG M2382D, works perfectly with Windows 7 with HDMI > HDMI.  This only has 2x HDMI and 1x VGA.  I connected my old HP L2045w DVI monitor via supplied HDMI > DVI adapter and it created the correct colour profile L2045w for the monitor and the colours look normal (compared to HDMI).  I reconnect my LG and no profile is created and it defaults to HD709-A with over exposed white.


    I was also sceptical about why are users reporting problems when I've never experienced any until it happened to me. I expected this from a machine running Windows.  Mountain Lion had serious battery issues and now this latest Mini has bugs, I wonder what bugs the latest iMac will have. This is not the Apple I heard about.  This is my first Apple desktop and I'm not impressed.

    Besides these issues the Mini is performing well after I installed 16gb ram to run Virtual machines.

    Edit: Mini delivered on 30th Oct, not Nov.

    I am also having the same issue with the blanking of the screen and then some static snow and then more blanking and flickering ans then it goes away and it is fine.  I have a late 2012 i7 2.3 factory upgraded to 8GB and Fusion drive.  It is connected HDMI -> HDMI to a Denon receiver which is connected (via HDMI) to a Samsung TV.  I am also having weird sound issues.  I will watch something with XBMC and the sound will be fine and then I go to something else and the sound will just be static.  If I exit XBMC and then go to something like iTunes the sound will be fine, then go back into XBMC and return to the item that had static sound and everything will be fine.  Very annoying.  Tempted to hook it back up via HDMI straight to the TV and optical to the receiver but I really want the pure HDMI hookups to work.

    Looks like like it's wide spread problem i have try all and the only fix i have found is to use the Thunderbolt port not the HDMI i'm using a MiniDisplay Port to DVI on my Samsung S27950D and so far so good not a black screen or a blink no snow and most defenatly no washed out colour as i was getting when using HDMI to HDMI or HDMI to DVIto me this looks like a driver problem that will be fixed by software update i don't think is a hardware problem as i have spend hours reading other forums trying to get to the bottom of this so what i did find was that with bootcamp and windows 7 the HDMI not problem with Linux same no problem however we are only getting it on Mac OSX for me the solution was a 3rd party $15 MiniDisplay port to DVI now all working great .

    Talked to Apple last night. Resetting the SMC didn't help. We zapped the PRAM, of course that didn't help.


    Then he emailed me this list of files to delete, haven't even looked yet:

    I contacted apple yesterday and the representitive let me know that this was a wide spread issue and that in the States they have started a voluntary program for people with the issue to submit their minis for further study of the issue. She also suggested that I hang on to mine as a replacement would most likely have the same issues.

  • ejoy_uk Level 1 Level 1 (0 points)

    An apple hardware engineer actually called me a few days back after I contact Apple care about this problem. He walked me through a list of quections to help identify extacly what happened. He explained that at Apple they have lot's of mini to test but none has such problem. However they are award of this issue and offered to exchange my mini free of charge so they can capture my unit to examine.


    I din't sent in my mini as I'm afraid the new one will be the same. However the blank screen only happened a couple of times a day each lasting 1-2 seconds so not a big problem for me.


    I just hope it's a software issue so a fix is on the way. If it's really a hardware problem, I can always exchange my mini later. I trust Apple will solve this before my one year warrenty runs out .

    Has anyone using a monitor that plugs directly into the HDMI port seen this? Or only those of us using the included DVI-HDMI adapter?

  • koyeung Level 1 Level 1 (0 points)

    Mine is direct HDMI connection between mac mini 2012 and monitor and have this issue occasionally.

    Darnit.  ;-)

    I'm connected via HDMI to DVI converter to Dell U2412M.  I recevied my mac mini 11/6/12.  I experienced a short blackout just a minute ago.  If it happens again I'm calling apple.



  • hank.wallace Level 1 Level 1 (0 points)

    Add me to the list of people experiencing the problem. I am using the HDMI to DVI adapter and will be calling Apple this afternoon or first thing Monday morning.

    Is anyone tried this? I am thinking negative but just in case.

  • ncalliari Level 1 Level 1 (0 points)

    Seriously Apple, this is so widespread it is ridiculous how this got past QA testing.

    Head of hardware QA should be fired IMO. This is not acceptable.

    If you stick an HDMI port on a product, test it before releasing said product to the public.


    Not only that, if you encounter issues with other of your recently released products, make sure you include testing for those same issues in your QA checklist for newer products using the same chipset/connector.


    This is QA 101 Apple!
