macOS High Sierra 10.13 slow graphics after battery sleep

2017 MacBook Pro 3.1Ghz

Having upgraded to macOS High Sierra 10.13, the graphics have slowed down significantly after sleep.


Steps to reproduce:

1. Close lid (default power settings)

2. Unplug from mains power

3. Wait 1 hour

4. Open lid and login

5. Try a graphics intensive app or game and notice a slow down?


Is this a known issue?


- Have a tried a clean install of 10.13.

- Have tried reverting to 10.12 (problem does not exist on 10.12.6)


The only option is to reboot.

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13)

After another week of testing, I have found that when I change my macbooks sleep mode to "sleep" instead of the default "safe sleep", this problem does not occur anymore...


Use this command to check your current sleep mode...

pmset -g | grep hibernatemode


Default is 3. I set mine to 0.


sudo pmset -a hibernatemode 0 - to set the desired sleep mode.


0 - Old style sleep mode, with RAM powered on while sleeping, safe sleep disabled, and super-fast wake.

1 - Hibernation mode, with RAM contents written to disk, system totally shut down while “sleeping,” and slower wake up, due to reading the contents of RAM off the hard drive.

3 - The default mode on machines introduced since about fall 2005. RAM is powered on while sleeping, but RAM contents are also written to disk before sleeping. In the event of total power loss, the system enters hibernation mode automatically.

5 - This is the same as mode 1, but it’s for those using secure virtual memory (in System Preferences -> Security).

7 - This is the same as mode 3, but it’s for those using secure virtual memory.

Until the release version of macOS 10.13.2 (17C88), I experienced Radeon Pro 460 graphics performance issues after a long time sleep.


After installing macOS 10.13.3 beta 3 (17D29a), the issues is not occurring until now.

I have to report that I no longer experience this issue (slowdown of graphics after sleep) since installing 10.13.2. Automatic graphics switching is on. No matter how long the sleep the graphics (for me) are now stable.

- No idea why. The only difference is that I upgraded from 10.12.6 to 10.13.2. (having reverted to it due to this issue in the first place)

Putting the machine to sleep with Radeon or Nvidia engaged has been one of our work arounds. Machine goes to bed fast and wakes up fast. To see the issue it needs to sleep with Integrated graphics.


So I wonder if that’s all that is going on here, do you have something like gfxCardStatus so you can see which chip is engaged when putting machine to sleep?


I do not use Chrome anymore because of its bloat and because it always forced the second graphics card to be engaged. I wonder if Firefox is doing the same? If that’s the case then no surprise you‘re only seeing full speed graphics.


Apart from the full blown slow down I have seen some less intense slow downs when other apps are running along side my game. When I shut down these apps I’ve seen the FPS go up right in front of my eyes. It seems like there is some sharing of resources going on.

Hi spearer,

Thanks for reaching out in Apple Support Communities. I understand that after upgrading to macOS High Sierra you're experiencing latency with the graphics on your Mac when waking it from sleep. I know it's important for your Mac to operate as you expect it to and I'd like to help. First, follow the steps here to reset the NVRAM on your Mac: How to reset NVRAM on your Mac

If the issue persists, use the steps here to reset the SMC: How to reset the System Management Controller (SMC) on your Mac

Let me know what you find.


Best Regards.

Same, or similar issue here. Even desktop apps, especially Java applications became very slow and unresponsive after the High Sierra Upgrade. I tried a completely new installation, resetting NVRAM, SMC, ... but the issue persisted. Also 10.13.1 did not improve the situation. I could hardly work on the MacBook anymore. It was much worse when working on an external display, which forced the switch to the Nvidia card.

I did now downgrade to Sierra and the problem is gone. Hopefully this will be resolved soon.

An update on the "fast or faster" point I tried to make previously.


After a sleep - graphics goes south - definitely "slow mood" - we all know that and hopefully Apple knows it too : - )


But even after a full shutdown / reboot I was reporting too much variation in the games I'm developing.


I seem to have narrowed this down now - it's a simple case of close all other apps in particular Safari with a bunch of youtube tabs ... then I get the very fastest speed.


Big difference:

Slow 25 FPS (needs a full reboot), fast 60 (close safari etc...), fastest 100 FPS - more like it.

Unfortunately, installing clean system (did many times) it's not changing anything. Turning off the SSD auto power off didn't change anything too. For me, only way is to get Sierra back and I'm advising this to anyone who only can. For an average user, the main different is the wallpaper. And so far, after got back to Sierra:


10:37 up 3 days, 8:23, 2 users, load averages: 1.50 1.49 1.48


And everything works like a charm. I think, we just have to wait until Apple will fix it.

Just throwing my hat in the ring, I had this problem on my Early 2013 MBP 15" and nothing helped to solved it except reverting back to Sierra. Don't waste your time with High Sierra. There are ZERO user features, and many low level system changes (AFPS/METAL2) which are just not finished yet. High Sierra is one massive beta test and Apple should be embarrassed by it. The latest security issue is just a symptom of that.
