you might have to use the flag alcid=11 i had to use the flag for my 7060 micro. for some reason the normal methods did not work. voodoohda did work though.

Jake Lo thank you for your response. 

 

I will give it a try with different layout-di, I found these one () layout 3, 11, 13, 15, 17, 18, 21, 27, 28, 30, 31, 99)

 

Bronxteck thanks for your response. 

 

I am using the flag alcid=11 in the OpenCore to override any configuration at the moment. 

 

Lets see how it goes with the various layout ids. Will keep you updated. 

 

If you have any other idea, let me know.

sorry for the late response.

i already change my hardware to lenovo m720q since i got the i7 version in cheap price, so cannot provide the bios config.

 

last time i checked the sleep, i'm still using the DP cable. i tried to sleep & wake by pressing the keyboard. i don't have the issue.

no testing with the HDMI cable one.

 

in my lenovo i have wake issue too, but fixed by doing this.

iGPU wake is partially broken due to numerous hacks apple uses in AppleGraphicsPowerManagement.kext with real Macs, to get around this you'll likely need igfxonln=1 to force all displays online. Obviously test first to make sure you have this issue.
