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

Thanks for the reply, but it is up to date.

I took my TBD to an authorized dealer and they are replacing the cord. They think it is the thunderbolt part of the cord that is having issues. I'll be sure to follow up if this doesn't fix it.

If you are not going to use the thunderbolt aspects of the display, it is a waste of money. Go buy a 1080p display for a couple hundred bucks. Even if you were looking to do thunderbolt hub work requirements, I'd still suggest going with a cheaper display until the current model is updated and improved after they iron out all the bugs. I'd return my two displays in a New York Minute if Apple would let me. So far I've spent a year "trouble shooting changes" with various tech support personel with zero results. Some of the problem posts for TB issues with these displays goes back to 2011. Go figure what Apple's priorities are?

I would be very careful about anything by Dell these days. From my reading over the last 3 or 4 years, Dell's quality and reliability have been reported as being lousy. I would do more homework and reading before going the Dell route. Samsung has always been a premium display maker. I'm sure there are others too. Maybe even HP. Check to see what Costco has and read their customer reviews. At some point Apple is going to need to update their displays to at least having TB 2. But more and more folks are going to 4K, so I wouldn't spend big bucks until I knew what I was going to be using for the next year vs. 3 or 4 years.

Thanks, Dennis!

Good luck with your display issues.

SONY makes beautiful displays.

Update: So far replacing the thunderbolt cord to my display has fixed my issue.

Thanks, Edward.

That's great advice. I have been looking at the Sony displays but they start WAY over $1000 and I just don't have that kind of budget for this monitor.

Thanks again.

I've been struggling with problems with my two TBDisplays for a year now. I'm working with one Apple tech now for 3 months. I keep sending them data captures with failures on every different setup they would like me to try next. After two weeks of silence and no replies to my emails, the guy comes back with the error reports are inconclusive. REALLY. That is the opposite, the results are conclusive, the TBDisplays are failing with every possible setup they ask me to do. How is that inconclusive? Who do we have to call to get these displays recalled? Who do I have to call to get my money back? I'm tired of this crap. This is BS pure and simple.

Well my semi local Apple store manager surprised the heck out of me. I brought my two TBDisplays and computer and TB hub in for a couple rounds of genius bar tech time. After going over the last 3 month long case file, they came to a conclusion. They offered to refund me my entire purchase costs, including my Apple Care plan for the two monitors that I had for nearly 16 months............I jumped at the offer. I wished for this answer, but never thought they would do this. My online and telephone Apple tech said he couldn't make that offer, nor would he tell me who could. The bottom line is Apple knows there is a problem with the TBDisplays. My best guess is there are problems with the built in hub in the displays. Whatever was plugged into the hub, whether another TB display or another hub or the USB ports. Those devices always seemed to be dropped for various reasons. Whether sleep mode or start up or who knows what else. I feel rather lucky at this point. I can now move forward instead of doing the constant try this, try that approach. I had over a year of that type of trouble shooting. Never once did an apple tech tell me they were looking for problems here. But the store manager and genius bar tech were well aware of the issues. Of course me bringing in two TBDisplays, computer and stuff in their original boxes on a busy saturday, might have helped. It doesn't help business to make a scene with a store full of customers. Thank you Apple.

This solved the problem for me:

On the wired keyboard connected to the TB display: press AND HOLD the space bar for SEVERAL seconds.... and... the display wakes up :-D

95%?

All due respect natmac.

It is a software glitch. Probably a heavy duty program jammed things up on sleep. Just shutdown and start your computer. It will start to wake up just fine.

Holly crap guys! A friend lend me a thunderbolt cable, and magic! it's working like a charm! 😮

They broke it again. Everything was fine until I updated to 10.12.2. Now the Thunderbolt display will not wake up again unless I unplug and replug the Thunderbolt cable. Really Apple??
