Hey,

It seems to me ever since I upgraded to 10.13.4 (i disabled auto sleep when screen is off) that the iMac Pro (base one) is longer to wake up from screen sleep (not full sleep, just screen sleep).

I can see the backlight turning on (black screen) for 1sec then I can see my desktop. It's not too terrible since it takes 1sec more but before it seemed to me it was instant : fade out then desktop.

If I wake up my screen instantly after putting it to sleep manually then it's instant with a nice fade out, but after 5sec of leaving it sleeping, it's not : no fade out, black screen for 1sec then instantly desktop with no fade out either.. Really weird.

Do you guys experience this ? Again monitor sleep, not the whole computer sleep.

EDIT : according to google it seems to be affecting every computer on 10.13.4

Boot and wake up time seem to gradually increase the more OS patches you install from Apple these days. My MacBook after the 10.13.4 update freezes one or several times after it wakes up from sleep. So your experience seems about right. I think people need to be more careful of OS updates, since Apple's QC isn't what it used to be. See what kind of experience other people have before you install, especially if you have a stable and smooth running machine. With iMac Pro it's more difficult, because it's still new product that needs bug fixes and better drivers.

You tell me about it, specially boot time.
I had to format my iMac 2013 and it reinstalled OS X 10.8.5 since it is what it came with and it boots faster on Fusion Drive than my iMac Pro on 10.13.X. It's ****ing blazing fast like 10sec to boot up, which is impressive.

OS X is bloated as hell, and it seems to me ever since Steve Jobs died OS X went worse and worse. I know he wasn't a programmer, but I suspect he was at least supervising the team and maybe even doing some QA on his side. Because OS X is full of bugs these days. Bugs that I can encounter in 10min of usage, makes you think that Apple even has a QA team ?

While I don’t have the iMac Pro, my 2017 iMac (with the fusion drive) is very slow to boot and wake from sleep in 10.13.4. I’m actually installing HS onto a Samsung T3 to see if that speeds it up any, as my 2017 MacBook Pro is very fast with 10.13.4. I No idea what’s going on with it.
 
OK, now I see certain OSX animations are broken too (like making a Youtube video fullscreen in Safari). Funny how there are fewer and fewer worthwhile additions in the latest OS versions, yet more and more bugs are creeping in...

I have a 2017 5K iMac with an SSD (no fusion drive) and it wakes from sleep the same as it did before I installed 10.13.4 and boots just as quick as pre 10.13.4.
 
chscag notice you lost fade in / fade out when monitor is exiting sleep though

I'm getting the "half-awake" grey screen for a second, like you do, before the screen is updated. But I'm also noticing something else. I have two Dell 5K displays attached to my iMP, and instead of coming on together with the main display like they used to, all of the monitors are coming on sequentially. First the main display, then the left Dell, and finally the right Dell. Each a few seconds apart.

Probably has something to do with the final support for eGPUs. The displays are being verified before being enabled. This is why you can now plug/unplug an eGPU from the Mac freely. Doing that without logging out first used to crash the system.

Now that I can freely turn on/off my eGPU at any time, I call it a fair trade. :)

This particular change seems to be a trade-off for being able to hot-plug an eGPU without having to log out. This is actually a great thing for anyone using an eGPU with a laptop. Since you can now just unplug it and go.
 
Thanks for confirming the issue. It's a 10.13.4 one for sure, no problem before.

I can also now say that I'm seeing more crashes in my photogrammetry app with the update. Switching a 3D game from full-screen to windowed while I had other apps running also caused some major flickering on the main display, and both attached monitors.
 
Although I have this issue on my iMac Pro even on 10.13.3, it seems every one here (right ?) has the problem where sound events is broken (volume up/down sounds weird, putting files to trash sounds weird, etc, specially when playing a video / mp3 at the same time), yet Apple seems surprised about this bug and ask me how to reproduce it.

Do they really test their product ? This bug was the first one I immediately noticed.

I have this sound issue too. I'm starting to repeat myself, but Apple's QC these days is disappointing. Also, Apple has yet to release proper graphics and audio drivers for Bootcamp, even thought we're nearly four months after the release of the iMac Pro. They are about the biggest company in the world, and they can't hire some extra guys to make decent drivers for their (very expensive) hardware? I'm starting to loose my patience with Apple, and their preachy liberal-in-chief Tim Cook doesn't exactly help.

Overall 10.13.4 has more bugs and issues for me than 10.13.3, and at the same time failed to fix most of the well-known issues with 10.13.3. Bravo, Apple.
