Studio Display Will Not Wake From Sleep

Love the Studio Display. Unfortunately, it will not wake up once it goes to sleep.


Video showing the issue:

https://player.vimeo.com/video/695566328?h=a311f9d8f1


Problem persists under different conditions:

  • Am currently using the Mac Studio, but have also tried it with M1 MacBook Pro (13",2020) as well as a 2013 Mac Pro (using a thunderbolt adapter). The issue remains, regardless of the setup.
  • I have tried not putting my Mac into sleep at all, and instead just locking the screen. But eventually the display turns off, and when I need to use my computer, it doesn't turn on again.
  • Have tried different thunderbolt cables, both Apple-branded and non-Apple-branded
  • Have tried using the Studio Display in a single-display set up, as well as in a dual-display set up
  • Have tried on macOS Monterey 12.3.1 (latest update)


Current Workarounds (if you can call them that; it's a significant interruption to workflow to do this each time I need to resume working at the computer)

  • Restarting the computer entirely
  • Unplugging and re-plugging in the thunderbolt cable
  • (if using a 2nd monitor), logging in, manually setting the machine to sleep, and then waking it up again: 50% of the time, when re-waking the Studio Display may come on the second time if lucky.


I'm not alone in experiencing this issue. There appear to be other threads related to this issue, albeit with slightly different set ups described. The difference is that I've tested this problem with several different Mac setups (MacBook, Mac Pro, Mac Studio) and confirm it appears to be a larger issue.


Current System Specifications:

  • Clean MacOS Install: When I set up my Mac Studio, I set it up as a clean install - so there are no randomly corrupted preference files that could have been brought over via data migration.
  • MacOS Version: 12.3.1 (build 21E258) --> note: the issue existed on 12.3 (i.e. not a new issue introduced by the .1 update)
  • Mac Studio (M1 Max/24-core GPU/ 64GB/ 1TB) --> note: also tested with 2020 MBP + 2013 MP
  • Monitors: Studio Display + Dell U2720Q --> note: also tested as a single-display setup without the Dell monitor.
  • Connection: Thunderbolt. Have tried with several different cables, including the Apple cable that came with the Studio Display itself.


I've taken a lot of time to put this together, including the video. If anyone has a contact at Apple that could help escalate this issue, I (and others) would be very appreciative. I have also filed a report here: Feedback - Displays - Apple


Thanks in advance.

Hi everyone, I'm the original poster who made the video and started the thread, and I'd like to follow up with some information that might be helpful.


In my case, it's a confirmed hardware issue with the Studio Display monitor itself. The monitor is being repaired by Apple. They are replacing the logic board and thunderbolt ports. I went through 2 levels of tech support with Apple, and shared data from my system with the Apple engineering team. Also did the firmware update for the Studio Display when that came out. The whole thing has been quite an ordeal, so I'd like to share the info below to make it easier for others with the same issue.



How to confirm that you have the same issue

Testing Procedure: log in to your computer. Then put it to sleep via Apple Menu -> Sleep. Wait 2-3 mins. Then wake by clicking your mouse or pressing a key on your keyboard. Repeat this procedure 4-5 times as it can be intermittent. And make sure that you wait 2-3 minutes after sleeping before waking.


Testing Specifications

  • Test with just the single Studio Display monitor and your computer, without anything else connected (except mouse and keyboard). In other words, leave all other monitors or accessories disconnected.
  • Test with different thunderbolt cables to confirm it's not an issue with your cable.
  • Test the same monitor with different computers to confirm it's not an issue with your computer.


If you perform the testing procedure as above and the issue persists, then you may have the same hardware issue that I did. If that's the case, then your best bet is to get it repaired under the 1 year AppleCare Warranty. Get started on that sooner rather than later because it takes a lot of time to go through the process: calling AppleCare, getting a case number, taking it to your nearest Apple Store so the Genius Bar can confirm it in person, ordering the parts, bringing the monitor back home, waiting for the store to tell you that the parts have come in, taking the monitor back to the store, and waiting for them to actually perform the repair.


If you have a different monitor sleep/wake issue

If you do not have a Studio Display, but are having sleep/wake issues with your monitor then you have a different problem. If you try the steps above and can't get the issue to show up in each setup, then you have a different problem. If you have a different problem, please start a different thread instead of posting a reply to this one, because this only causes confusion for others.


Finally, if everyone could please mark this post as "Helpful" so the testing steps above can be shown more prominently to people who might also be having this issue. Thank you everyone who contributed and tried to help solve the problem.
