Display slow to wake after High Sierra10.13.6 update

I can hear the boot drive (HDD) spin-up immediately when I click the mouse or tap the escape key on the keyboard but the display takes about 10 seconds to wake.

Default sleep mode setting - "hibernatemode 0"

What I did:

-Unchecked "Put hard disks to sleep when possible" which did not clear the issue.

-Reset SMC which did not clear the issue.

-Reset PRAM/NVRAM which did not clear the issue.

Mac Pro, macOS High Sierra (10.13.6), Mac Pro 5,1 Intel Xeon 2.66Ghz

Just to let you know, I have the same "display slow to illuminate after waking from sleep" since macOS 10.13.6. This happens on both of my iMacs, mid 2011 and late 2014. The displays take about 20 seconds to illuminate after waking from sleep. Send feedback to Apple, I already have.

I'm on a Mac Mini Late 2012 with similar issues. Didn't happen before the update, now I can hear my audio "pop" back on, all external lights for USB devices come on, but it takes forever for the display (HDMI) to kick back on. Anywhere from 5 seconds to 12 seconds since the update.

My Mac has some upgrades, including internal SSD and second HDD, but booted pretty good prior to this update.

UPDATE:

I was contacted by Apple on July 20. They asked for and received my "sysdiagnose" results. I believe we should expect this to be resolved in the next update. Since it is not a security concern but rather just a nuisance I don't expect it to be a standalone update.

Thanks for update, that's very helpful. I just wish Apple would test updates properly before releasing them. There are always seemingly obvious glitches that simple use shows up, and yet are not spotted before release. If you took a vehicle to a garage for a tune-up you would not be very happy if it came back with problems each time because, the garage would go broke by reputation, and yet Apple have us all hooked.

As much as I would like to have an immediate fix for this I would not compare auto-repair problems to software glitches. Auto repair is on a case by case basis. Software updates are issued to millions of machines with different hardware and software configurations of varying age. For example: You wouldn't flash a '96 Honda Civic's ECU/ECM with a 2018 Chevy Camaro SS firmware. It may sound like it would be a performance enhancement but in reality it would render the Civic useless. 😉

Fair points, however, Apple have made all the machines and the software so, they know what each can do/does and it is for them to configure things to work. That is their responsibility. The garage does not supply free labour, but Apple customers do. 🙂

I was also contacted on 7/20/18 and submitted the same info.

I guess I just want to stress the importance of submitting feedback to Apple about issues. Some of these issues only affect a few users. The more voices that speak up when an issue appears and the sooner they speak up, the better chance it will be fixed.

I see the same thing, but it started in 10.13.5. I can get the monitor to wake immediately if I press the power button instead of a key or mouse.

I have this too. It's all over the internet and elsewhere in the Apple Support Forums, and it's been reported via Apple Feedback, however Apple have done nothing to resolve it.
