Slower to wake from sleep after High Sierra?

    I've noticed that my 2016 TB MBP 13" is much slower to wake from sleep after installing High Sierra. When I open the lid, the screen often stays black for several seconds. I have to hit a few keys to get to the login screen, and even then Touch ID can take a while. Anyone else seeing this?

    No problem here on my 2017 MB and old 2009 MacBook Pro. Those were clean installs though, and don't have a huge amount of data or software on them.

    With my 2017 iMac I sometimes get what you describe, but that actually a huge improvement from before. Before with both Sierra and High Sierra (upgrade) I would get 5-7 delays every time. Then I did a clean install and manually copied my user data over. Delays are now 1 second, or if extended sleep, a few seconds.

    It’s the deep sleep that seems longer now on my 2017 TB. Only sometimes though.

    High Sierra is still very buggy though, so don’t worry too much.

    Yes, mine takes forever as well. I am not too happy with High Sierra. It has too many things that don't work the same, and is missing stuff like "all my files"

    Seems to be a trend. Takes Macs forever to fall asleep now as well. On far older versions of OSX, my Mac Pro would sleep almost instantly. Now, it seems to take 20-30 seconds. That being said, it DOES have more RAM now. I'm assuming that's the reason for it.

    As for my MacBook Pro, which now has HS, I'll have to see... I am not sure I've noticed anything.

    I thought this happened but then realized I simply had done a clean install and needed to run pmset to get hibernate mode to behave correctly, like so:

    (enter this in terminal, followed by password)

    sudo pmset -a standbydelay 43200

    This will make the computer wait 12 hours before it goes into full hibernation mode. Wake from sleep is instant, wake from hibernate takes a while.

    On my system I actually set it to 24 hours, because I really always want sleep mode. Sleep mode uses a tiny bit of battery, while hibernate uses none. So the trade-off is, the computer will lose a bit of battery, but wake faster. I love the instant wake, so I don't care.

    24 hours is like this:
    sudo pmset -a standbydelay 86400

    Note: This only applies to laptops.

    Edit: Didn't really fix it, this is a different issue. in High Sierra, the login screen takes a few seconds to appear. Vs. when there's no login screen and the system just wakes from sleep, it takes less than 1 second.

    I am now testing turning off the sleep password... so wake from sleep won't show the login screen. I wonder if it has to do with that.

    I had it set to 1 minute before, and closing / opening the lid wake from sleep was instant. So maybe it's the login requirement - I have a feeling it might be related to disk encryption in some way.... or maybe they encrypt the RAM?

    I am seeing a slower wake up on my macbook air early 2014 running Sierra - the screen is blank (backlight light comes on immediately), for up to 10 seconds. I can't install high sierra because I installed a OWC 1TB drive and the HS installer doesn't support it.

    I have an older imac (2009) that I installed High Sierra using the mac os patcher tool and on occasion it just won't wake up from deep sleep - the backlight comes on, but the screen never displays anything. I can remote it to using vnc viewer and and I ssh into it.

    The issues seem to be related.

    I had a similar issue - turning off notifications on the lock screen seemed to help: Settings > Notifications > each of the apps I unchecked the "Show notification on Lock screen". I also disabled automated update checking in App Store (App Store > Preferences > uncheck "Automatically check for updates") as that was also another process that kicked off always.

    I have the same issue with a Mac mini 2012 Quad-i7. With Sierra it came out of sleep in a couple seconds. With High Sierra, it is about 12-13 seconds. Blank screen, external spinning drives turning on very late.

    Upgrading to HS has caused several hassles (Safari hanging, an incompatible webcam), never happened since first upgrading to OS X. And to solve the problems with Safari I had to clean all the preferences manually.
