Nov 22, 2014 2:37 AM in response to MarkTahaby Carla@Jovial,Thank you so much for posting this message. After struggling with this display for years and ultimately deciding to store it on the floor to collect dust, I found this thread today and your post fixed my problem and it was so simple. Thanks again!

Nov 28, 2014 6:29 AM in response to Raintreecaby Raintreeca,Well that did not last a long time. Despite the new firmware and the installing of 10.10.1 the display is back to it's old tricks and going blank coming out of sleep. I have contacted the T2 Applecare person I have been dealing with but no response as of yet to what looks to me to be a hardware issue with the TBD.

Nov 28, 2014 5:45 PM in response to GooberGrape70by washparkhorn,I have followed this problem for more than a year. Had all the same problems. I had the intermittent moments when it would come on. Then it would go out again. Waited for some software update to fix it.
Purchased a thunderbolt to thunderbolt cable - it works. Should have bought a cable over a year ago. TB to TB cable.

Nov 29, 2014 8:06 AM in response to washparkhornby Clintster,Ditto for me. Just get a new Thunderbolt to Thunderbolt cable. Since I did this 2 months, not a single problem.

Dec 1, 2014 9:15 AM in response to Clintsterby anfieldjw,I have recently had two TBDs with the same problem. The first was from Amazon - I was informed by Apple support that it was a refurbished unit previously suppled in the US, and that it must be faulty. I returned it to Amazon for a refund and went to the Apple Store to buy a band new one at full price. Guess what? It had the same problem. Back to the Genius Bar where I was able to demonstrate the fault, but a suite of tests failed to identify any problem with either the display or my 2011 MacBook Pro. They offered to keep it for more tests, and/or to reinstall the OS, but having read this blog I knew it was futile.I suggested trying a separate TB cable but this wasn't followed up. Anyway I got a refund and bought a Philips 272P4QPJKEB/00 complete with webcam, USB hub etc. It is not as lovely as a TBD, but it was half the price and 'it just works'.

Dec 2, 2014 2:19 PM in response to anfieldjwby Dennis L Jacob,Well I spent over an hour with another tech doing countless reboots and purging of settings in another attempt at ending the never ending non waking TBDisplays. I have two of them connected to my MBPro. Well all of the work was proven not to work after 18 hours when the display didn't wake up the following morning. I've tried switching display positions and that didn't work either. So the tech I was working with is off until thursday. He'll get my emails then and we will try the next option. It is very tiring to always have to either reboot or unplug one display to connect it again on a nearly daily basis. Not using the built in TB cable to me is a defect. If I use a TB cable from one display to the next, I can't daisy chain to another TB device. What good is that? The other issue is anything plugged into the usb ports get ejected - incorrectly and if it is hard drives, well they don't like that either. FRUSTRATION on $1k displays - really?

Dec 2, 2014 6:14 PM in response to Dennis L Jacobby Raintreeca,After doing the firmware update, 1.2, and then 10.10.1 OS update and having a week or so of bliss I am back to the same problem with the sleep/blank screen issue. I have talked with the applecare T2 rep and have sent off the internal reads to the Apple engineers yet again to see what ails the TBD. She hopes to have some news by tomorrow--we will see.
I have been able to use my work around of engaging at least 3 keyboard keys and the mouse at the same time to bring the TBD out of sleep and get a full screen.Though, I can't say it works every time, it is better than having to restart all the time.

Dec 5, 2014 12:01 PM in response to GooberGrape70by Adam Henley,I also have this problem with my 4k Samsung display. If the MBP sleeps for too long it will not wake the display over TB when I wake the computer. My easy keyboard shortcut solution is: Shift + Ctrl + Eject/Power (depending on your keyboard.) This command puts all displays to sleep and then you can hit any key and all your displays wake back up.
Seems a shame we have to do anything to make our connected displays wake up. I don't really mind as I am using my laptop in one location and use the monitor about ten feet away as a stand along computer style set up. It is actually kind of nice that the display does not wake up unless I need it in my case. If the display was right next to my laptop this would have been super annoying though. I hope this keyboard shortcut works for others!

Dec 10, 2014 4:44 PM in response to GooberGrape70by Chepe,Shouldn’t the Firmware Update 1.2 was supposed to fix it? How can a problem like this, for such an expensive product can’t be solved by Apple? Frustration falls short.

Dec 10, 2014 5:46 PM in response to washparkhornby Sky King,Hello Washparkhorn.
Thanks for your information. So are you saying your bypassed the standard cable that comes with the TBD and installed a new TB cable from the TB port on the TBD to your MacPro and that cured it?
I have to keep unplugging my TBD to get it to work and when sleeps and if I forget to eject my back up drive I get the error message that I could be damaging the drive by not ejecting.
I concur on the thread that Apple engineers screwed us on this one. Additionally they put out a new iMac with Retina and didn't update the Thunderbolt Display. *** Apple?

Dec 11, 2014 3:45 PM in response to Clintsterby Raintreeca,Sorry, I tried that 2 months ago and it did not work--at least with my set up (Mac mini to TBD).

Dec 11, 2014 3:53 PM in response to Clintsterby Sky King,Hi Clintster:
What are connecting to your TBD?
My System is:
MacBook Pro (13-inch, Mid 2012)
2.9 GHz Intel Core i7
8 GB 1600 MHz DDR3
Intel HD Graphics 4000 1024 MB

Dec 11, 2014 5:07 PM in response to Sky Kingby washparkhorn,Yes Sky King. I connected my mid-2012 13 inch MacBook Air (2 GHz i7) to the TBD with a Apple Store TB to TB cable. The TBD lit up. The power side of the hardwired TBD cable always worked (I could charge the MBA with the cable). After it came "back to life" for a few days, I plugged the regular TBD thunderbolt cable into the MBA and it worked long enough to perform the firmware update. I was able to use that cable for about 24 hours before the TBD went dark again. I used the TB to TB cable again and the monitor lit back up right away and continues to work.
My problem feels like a cable pinching problem with the hardwired cable. The spread between the power cable and the TB side of the hardwired TBD cable is tight with the 13 inch MBA. The cable is taut and I have to twist the cable a bit to make it fit.
I have a second TBD that was purchased at the same time. It has never given me a problem. I daisy chained the TBD's when I first purchased the monitors. The problem with the one monitor started a few months later. The monitor connected to the MBA went dark. I switched the monitors so the other monitor was connected to the MBA and both worked. If I had to guess, it is the stretching and twisting of the cable that caused one of my monitors to stay asleep initially. I think the cable relaxes and works intermittently.
Knock on wood, but the TB to TB cable has worked. I haven't tried to daisy chain the monitors together since I use the "good" TBD for a Mac-Mini. But if was going to try, I would use the good monitor and connect it to computer. I would use the TB to TB cable between the monitors and hope it worked.
Good luck all. It is certainly a frustrating problem. I should have tried the cable fix earlier. I assumed the monitor was toast. It's great having it back up and alive.
