Thunderbolt Display will not wake up after sleep!!!!!!

Ditto for me. Just get a new Thunderbolt to Thunderbolt cable. Since I did this 2 months, not a single problem.

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?

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.

Sorry, I tried that 2 months ago and it did not work--at least with my set up (Mac mini to TBD).

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

Here's the problem I have. If you use a TB cable connected to your mac and then to the TBD, you lose the thunderbolt hub daisy chain. If I didn't want to have a TB hub monitor, I would have purchased something for hundreds of dollars less. Then you still have the risk of the usb hub to eject devices if something else goes wrong. I purchased two new TBDisplays less than a year ago and I'm still dealing with tech support going on 9 months. I'm get tired of trying this work around and the next. As of now - I want to return these things and I'll go elsewhere for my displays. Apple why do we have to screw around with work arounds and try this......or try that........ Just admit there's a problem and recall these things. I'm very tired of screwing around.

Thanks for the suggestion, but I found this thread months ago and tried it but to no avail on my set up.

I tried that fix back a couple months ago. The "fix" lasted a day or two, then back to non-wakeee-wakeee. The problem still exists.

Been there, done that. After a couple days, I was back to non-waking TBDisplay. I've tried every method mentioned in either the forum chats or from Apple Tech support folks. The only thing I haven't tried was upgrading to Yosemite. Since other folks are reporting the same problems under Yosemite, I haven't gone there yet. I'm not one to fix something that isn't broken yet. So I'm waiting for the OSX to be updated a few times while early users work the bugs out. My Tech person suggested that I make a new partition and install Yosemite on that drive to try out. But for the last two weeks, my tech person isn't returning emails or calls. So I'm guessing they don't have an answer and are just dumping these TBDisplay problems and moving on to folks that are more important. Why else would they stop providing support. Both of my TBDisplays are protected with Apple Care policies. So they aren't making money on taking my calls. They have bigger fish to fry I guess.

In a word, ditto.

okay... :-/

well, I had the problem with Mavericks for a couple of days now, then updated to Yosemite and the problem still existed.

But resetting the SCM worked for me. For now...

I've tried that and still have the same problems. No responses from Apple after tech's have tried all of these quick fixes. They won't return phone calls or email requests for help.

I've been suffering the 3 and 4 times a day of non waking TBDisplays. Maybe it is time for a class action lawsuit. The only course different from your efforts and mine are I haven't upgraded to yosemite yet. I didn't want to compound the problem or possible problems. My tech support guy won't return emails or phone calls. This is ridiculous. I have two of these monitors and they haven't worked from day one. I'm ****** and don't have the time to spend 3 or 4 hours on a online chat or phone call every day when this happens. I'd think they are too busy too, but yet here we sit.

Since there is no power button on TBD, unplugging and plugging the display cable from imac did the trick.
