esisoon Level 1 (5 points)

I bought the first version of the MBP Retina and I'm loving it! So what better companion to use than the 27" Thunderbolt Display...


So I've been using it since the first day I got my MBP Retina. Everyday when I leave work, I log-out from my computer, and when I get in in the morning, I just move my mouse and both my displays wake up. This has never been a problem until this morning.


I have tried unplugging the power, doing a power cycle, disconnecting all USB devices from the Thunderbolt, etc. Nothing works.


Does anyone have an idea?

MacBook Pro with Retina display, OS X Mountain Lion (10.8)

    Forgot to mention - the magsafe plug from the thunderbolt display charges my MBP Retina just fine. However, anything plugged to the display cannot be seen on my MBP.

    bump... same problem

    I've been using a Thunderbolt display with my MBA.  I have had the same problem.  My display was exchanged by the local store, but the problem persisted.  By trial and error, I have worked out a "protocol" that seems to deter (if not totally eliminate) the problem.  I do the following (in strict order):


    1.     Eject any drives attached (via the display)

    2.     Put the MBA to sleep (or shutdown)

    3.     Turn off the power to the display

    4.     Disconnect all cables between the MBA and the display.


    When reconnecting:-


    1.     Connect all cables

    2.     Turn on power to the display

    3.     Wake the MBA


    Every so often I have missed a step (usually not putting the MBA to sleep).  There is then a 50:50 chance whether the display will come to life immediately on connecting.  When it does not, leaving it connected with the display power off for 5+ minutes, then switching on the display power, seems to do the trick.  If not, repeat (irritating, I know) -- turn off the power, leave for 5+ minutes then power on again.


    Hope this helps.

    I used your link to find out how to make my Thunderbolt display wake up, but I did not find anything related to this particular problem om that page. What exactly are you referring to?

  • Nepse Level 1 (0 points)

    Here is how to fix the problem with 27" Thunderbolt screen waking up from sleep. Just do as esisoon indicated, check out the instructions for resetting NVRAM and PRAM on . Just follow the simple instructions 1-6, and check out whether you need to reset screen resolution, time zone, sound etc when you are done. The whole procedure does not take more than 5 minutes. Very likely the issue with the wakeup will be solved. Good luck to the rest of you with this problem, and thank you esisoon!

    Just to also add, this solution is to reset the NVRAM and PRAM, my original request for help for the thunderbolt display was caused by the Thunderbolt port freezing. Once I did the reset it was solved, so if your thunderbolt display is broken this will not solve the problem, my problem stemmed from the TB port on my MBPr.


    Glad this solved your problem, Nepse!

    My joy unfortunately was short. After having left the harddrive on my MBP sleeoping overnight, the screen would not wake up this morning. It is back to acting like prior to my procedure resetting VRAM and PRAM. There is obviously a bug which I hope will be resolved,– hopefully sooner rather than later.

    Hello there,


    I had the same Problem with my 2011 Macbook Pro 13" (10.8.2) and a TB-Display. PRAM reset didn't help. Yesterday I did a full reinstall leaving out the Macbook Pro prefs when restoring from TimeMachine. Until now no problems.


    Best Regard,

    Hello again,


    I have to admit that it solved the problem for 2 days, now it's back to the former miserable state.


    I have to pull the TB-plug and the AC-plug to reviev the display.


    Best regards,

    How do you "turn off power to the display"?

    My 27" Thunderbolt has no On/off switch in sofar as I know

    Did you mean unplugging the electric cord?


    Does your MBP waken immediately?Or is does it, also, stay asleep

  • Joerg Daehn Level 1 (0 points)

    Hi Barbara,


    pull the plug. I wish this thing had an on-off-switch. Apple idiosynchrasy. Like non-user-serviceable batteries and memory slots. Oh well.


    For some unknown reason the TB-Display has stopped it's annnoying behavior. I don't know how long it will last.


    Hoping for an update.

    Thanks, I was not sure if that was what you meant

    Yup, an on-off switch would be nice

    Hi Barbara,


    actually I didn't say anything like that. To quote myself:

    I have to pull the TB-plug and the AC-plug

    which is somewhat different than pushing a knob or a switch. I know I am nitpicking here but that is what I am famous for among my friends ;-)


    Have a nice day (even with a somewhat glitchy Apple product on your desk),


    J. Daehn
