10.12.4 display sleep bug

Update:

It's been about 1 week since the update to High Sierra and the sleep bug seems to be gone at least for now. I have tested it every day, sometimes several times a day and so far it brings up all the displays correctly. I can see a big difference on how it seems to wake the displays now from what it did before. Before when the bug was occurring, it would bring up the displays in a chaotic random way. Now, it seems to be structured, the iMac display comes up first then the 2 flanking monitors come on in sync with each other. It's very smooth now. Also, I noticed some other differences such as if I switch inputs on one of the 4K monitors to show my PC on another input then switch back, the mac with quickly flash all screens and as if it is looking to resync everything correctly. This never happened before with the buggy version. So far everything looks good, fingers crossed that it stays this way!

My problem went away when parallels issued a patch.

I am one of the original people to post on this issue, and have tried many things in an attempt to resolve it. So far, I can also confirm that this problem appears to be gone in macOS 10.13! I updated to the final release yesterday. I did not do a clean install, just updated. Everything seemed to install fine, file system converted to APFS, no issues with the process. I've intentionally set my display timeout very low, manually put the system to sleep, locked the screen, all many times. So far, so good.

I updated to the official 10.13 release as soon as it came out in hopes to solve this issues. Several days later, and I haven't had a monitor not return to normal after the monitors have gone to sleep. So far, so good.

Good news! I no longer suffer from this issue under macOS 10.13.

I have installed beta macOS 10.13 (High Sierra) - specifically GM 17A362a on my affected machine. I installed it from scratch by formatting a partition to APFS and installing the system cleanly. Then I reproduced my previous setup (reinstalled all the apps and jazz).

So far have been running it for 7-ish days with many instances of waking displays from sleep and not (yet) experienced the issue. Fingers crossed!

Like everyone else here, I have the same problem.

The only thing that's been working for me is each day, I go into Energy Saver, uncheck "Prevent computer from sleeping automatically when the display is off", leave Energy Saver, go back into it and re-check it again. Since I've been doing that each morning after waking the screens, (5 weeks? except weekends), the problem has only returned once (see below). I'm unsure if leaving Energy Saver is a needed step but it's working for me.

At one point during this time, I neglected to perform my routine, and within about 4 days, the bug happened again. Since I started it again, it hasn't returned.

From my investigation, clicking on that checkbox modifies the sleep time in minutes. Clicking on it effectively calls "

pmset sleep 0"

pmset sleep [value of the 'Turn display off after' slider]".

So, if I have turn display off after 3 hrs, set, and have "Prevent computer from sleeping automatically when the display is off" checked, it's effectively the same as saying "

pmset sleep 180

I've thought about attempting to create an automated solution to do this daily (ie cron job calling I think

sudo pmset sleep [time in minutes]

I have no idea how/if this could correlate to stopping the bug but at a minimum, clicking on the checkbox daily works for me.

The only other thing worth noting is my Mac is using Carbon Copy Cloner which wakes the displays each day at 5AM. Usually, the displays are still operational by the time I get behind my computer - within the 3 hr timeout).

Just an update for those that had the issue:

Since the upgrade to High Sierra which I did the day of the release the problem has not returned so far. Has anyone else completed the upgrade and had the issue fixed?

Thanks for the info, in the end, Apple needs to really step up and fix this issue. Not so sure that will happen. I can only hope that High Sierra will fix the issue but may also introduce new ones at the same time. There is no doubt that this bug was introduced in 10.12.4 and it relates to the energy saver code but the fix would ultimately have to come from Apple!

If this follows past experience, it takes sometimes up to 2-3 days for the problem to re-surface after an OS update.

Since my iMac 5K is in production, we never update to .0 releases so we’ll be waiting for 10.13.1 anyway.

Depressing news...

Because 10.13 is a new OS release, we can post NEW bug reports so I would recommend that anyone who can reproduce this problem on 10.13 file detailed bug reports. Anyone can create a developer account for free and file a bug report.

I have the same issue with sleep / wake mode, EXCEPT it started when I update to High sierra. I run parallels 13 with windows 10 on my mac and the problem only appears when P13 is running. when I close P13, the problem disappears.

I have a 27" 5K iMac with 2 flanking 28" 4K displays and the issue is gone. Since the upgrade to High Sierra, I have not had the problem. Fingers crossed that it stays this way!

I upgraded about a week ago and plugged my second monitor in once more. So far the issue has not returned. Previously it was happening every few days.

Update: I have reached out to Apple several times in the last couple months and no response! It is quite apparent that Apple has given up on this problem or has just decided to ignore it. I was going to buy the new iPhoneX but decided to go with the Galaxy Note 8, likewise, I am angry enough at Apple that I am seriously considering replacing my macs with PC's. The other day I had the bug black out all my monitors after a quick flash of video and could not get them back after a couple reboots. Finally, on the third reboot, I was good but lost 2 USB drives that took another 15 minutes of my time to recover them correctly. All this happened because I was forced to do a hard power down because I could not access the desktop to correctly reset the machine!

Apple, get your act together!!!

Day one, my iMac woke from an overnight sleep and all monitors came up extremely smooth. One difference I did notice which I rarely noticed before is that the iMac screen (Center) came up first and did not flash or blank on or off, then the 2 flanking screens came up after the center in sync. Before it was just a random mess!

Today is also the 1 week point for me with macOS 10.3, and I have also had no further issues. I only have a single external Dell P2715Q display attached. I am also running Parallels 13, with Windows 7 and Windows 10, still no issues. I have noticed when waking my system, the screens flash, and then flash again. I do not recall if that is the same as prior to this issue.
