    I have exactly the same problem, but here in the Apple Store in Paris, they claim to you that the firmware is coming, but F*** can't I wait i have to work and with no machines i'm SO deep in trouble.


    I have a brand new Mac Mini 2,5, and the apple LED 24, which i bought in january 2010, and they certainly made me notice that the warranty was over... nice move Apple...


    I am NOT LETTING THIS GO, i WANT my 27 inches, for compensation, it's been like 6 hours of my life i spent in the apple store in only a few days... grrrrhhhh


    I don't understand, and i'm ready to pay the difference between the price of my LED 24 and the new 27, which is only like 200€.... but still, DO SOMETHING Apple !

    I have escalated as much as I could ..... I am also very annoyed!


    This is my last email to Senior Advisor to escalate:

    It has been a month now that my display is flickering, and frankly speaking this is not usable. The New MAC Mini (Thunderbolt port) was advertised as Backward compatible with my existing 24" LED Display.  This is what has led my purchase decision. It is not. Whilst I accept that some equipment might be faulty, the amount of time I have already spent explaining this issue and talking to Apple is not acceptable. The answer : No timeline has been confirmed is not acceptable after a month.


    As a consumer, I do have rights. One of my rights is to be sold Equipment which works as advertised.


    As it stands today, what are the options:

    1) Apple acknowledge the problem and fix it. Either send me a firmware, or replace my display with one that Apple knows works with the New Mac Mini.

    2) I take my case to Consumer Rights: Under the Sale of Goods Act, the retailer must either repair or replace the goods 'within a reasonable time but without causing significant inconvenience'.

    Today Apple released an EFI-Update for the MacMini. I just wanted to know if this update solves the Thunderbolt problems mentioned above because the update-description says:


    "This update includes fixes that enhance the stability of Lion Recovery from an Internet connection, and resolve issues with Apple Thunderbolt Display compatibility and Thunderbolt Target Disk Mode performance on Mac Mini (mid 2011) models."

    No joy with the new EFI update for Mac Mini and Cinema Display blackout and flickering...

    Here's what I did with a Mac Mini and it seemed to help.  (I did replace the Mac first -- what a pain. When I saw the flicker again, my heart sunk and almost forked out a grand for the 27" display.)  


    I suspected some kind of voltage incompatibility, with the Thunderbolt output on the Mac being too high for the 24" ACD. So, I added an MDP/USB extension line to knock it down some.  (The length on the ACD is rediculously short anyway).  Well, it reduced significantly, but did not eliminate, the flicker.  I added another extension on just the MDP line and appears to (almost 100%) eliminated it.  I have seen one blanking in about a week.

    Same here. I have mac mini 2011 I% connected to cinema display 24inch.  Problem is screen going black intermittently and screen flickr- NOT happy!!!

  • missilemike Level 1 Level 1 (0 points)

    tbromine that's an interesting idea.  How long were your extension cables?  I just bought a 15 foot usb/mdp expansion on ebay for 14$- hoping that will do the trick.


    I have the latest developer release of 10.7.2, and that doesn't fix it, nor does the new efi update.  If it is a voltage problem, I wonder if it can be fixed at all with software.

  • Jason W-D Level 1 Level 1 (20 points)

    Do you have a link to these MDP/USB lines?


    PS: if you tweet about this I suggest using #ThunderboltFail

  • charles.m.h. Level 1 Level 1 (0 points)



    I agree with the previous posts, I also suspect that the issue is related to voltage. I believe that the USB / MiniDisplay extension is a smart option. I wish I had known before buying an Altona DVI to HDMI adapter, which is costly, and uses too much cabling an ports. However, the problem has disappeared.


    By the way, I have updated the Firmware and Software this morning and re-tested. No joy. Still flickering.

    I'm having the same problem since two months now... According 2nd level support agent, "it should be solved with version 10.7.2". Unfortunately he had already said "it will be solved with 10.7.1"...


    I think time for patience has gone. I think we all wait because it is an Apple product and we are kind of addicted wich makes us tolerant but for me the limit is reached. This situation is just unacceptable

    Hello everyone.

    Sadly I have to join you also.

    Bought a new iMac 21,5" and when connected to my ACD 24" I get a lot of flickering also...

    This *****!! How hard can it be to fix this!



  • marionfromparis Level 1 Level 1 (0 points)


    Can we have HOPE on this ????


    I returned my macmini after just 4 days desperatly trying to find a solution.

    SO i can't try the update (link above)....


    If you tell me this works out, i'm going to rebuy my mac mini right away, cuz' i need it to work.

    (i have the eternal problem of flickring when connecting my newgeneration mac mini with my 1year old apple LED cinema display 24 pouces)


    Awaiting for you guys



  • Jason W-D Level 1 Level 1 (20 points)

    Marion, I'm afraid that firmware is for the new Thunderbolt Display. It is nothing to with Mini Display Port monitors like the 24" ACD

  • marionfromparis Level 1 Level 1 (0 points)

    ugh, in a rush i did'nt see the word thunderbolt... daamn


    *losing hope as we speak*
