This guide is almost a exact copy of the one posted by MikeyN here. We all have to thank to MacRumors community that all of them have been working really hard to create a workable solution to all of us. You can check my previous post also 1 & 2. Till this moment this is my favorite solution and I even have the brightness back to my computer. Ok!!!!!! There is a third, and I think final, solution to totally deactivate the dGPU.

Update 2019.10.20-22.10 EEST: I don’t have this computer anymore, so I’m sorry but probably I’m not going to be able to help you. Update 2018.01.21-09.20 EET: I just installed macOS update 10.13.3 and after testing a little bit I got to the conclusion that what work best for me is to set pmset -a gpuswitch 1 But I don’t know if it’s really that or it’s other thing. I changed to 0 and then to 2 again, and seems that everything is normal again. I really don’t know what is the reason, but seems it’s related to the gpuswitch parameter. Also the computer didn’t turn off and got stuck in a black screen. Everything worked fine, but on wake up of hibernation I got a black screen a couple of times.

Update 2018.01.09-21.35 EET: After install the security update to mitigate the effects of Spectre, I have to apply the fix again as explained here. Update 2017.12.18-14.42 EET: I’ve tried to wake up from hibernation without gxfCardStatus and it worked pretty well I didn’t have any issue, so if you don’t want to have it installed or at least running in the background I think it’s OK. I’ve updated steps 11 and 12 in consequence.

gfxCardStatus can help since the problem after wake up is the dGPU activates and the computer freezes.

pmset gpuswitch option can help, but it’s really undocumented officially, so we really don’t know what the values for 0, 1 and 2 stand for, and can vary from machine to machine I guess, or at least to macOS version to version.

You don’t use AMDGPUWakeHandler with this solution, since it could create a kernel panic… so for that reason doesn’t work.

Update 2017.12.13-09.08 EET: After checking about the wake up problem after sleeping / hibernating with the people form MacRumors, I reached some conclusions. Depending on if I have AMDGPUWakeHandler on or off I get different outputs, but none of those end in a successful wakeup. I tried the other Volumes also but the system doesn't start.Īt the moment I install the system again to get back to a clean High Sierra.Update 2017.12.12-14.20 EET: whether or not I use the AMDGPUWakeHandler and whether I sleep or hibernate I can’t wake up of the hibernation/sleep.

After rebooting the MacBook Pro turns off after the half of loading. Know I get the message the directory is not empty.

But the problem is that High Sierra on a SSD have the new apfs system. After I've restarted it didn't work and I tried the steps again. Then I've updated the MacBook Pro to High Sierra.

Yesterday I tried the solution for my MacBook Pro under Sierra from the forum under this link: MacBook Pro: How to disable discrete GPU permanently from EFI?
