General Discussion: Intel Ice Lake Graphics on macOS Catalina

Hervé · September 13, 2020

Folks, it would appear a warning and reminder is required here! This thread is a general discussion related to getting Ice Lake graphics working in Catalina, it's not a thread to discuss issues related to audio, Youtube video playback, CPU power management, TouchPad or Thunderbolt ports issues on your own Ice Lake platforms.

:offtopic:

Given that small group of people had began hijacking this thread for unrelated matters, substantial cleanup was made and all off-topic posts were removed. Any further off-topic posts will deleted without prior notice. I remind everyone that unrelated matters can be discussed in their own dedicated and fully appropriate threads.

Thank you for keeping this thread on-topic and not turning it into a trash can.

@Ab2774 or @vokhotnikov were you able to fix your black screen isuue? It seems that the display works but no backlight as I can see the login screen if I use a flashlight. But the backlight starts working after approximately 5 min.

No, I'm still having the same issue as yours. Every reboot it's a lottery. Sometimes the screen works fine, but other times I have to wait some 5 minutes before the screen turns on.

I have activated SSH and VNC sharing - I can login into the laptop during the black screen period.

Also I tried several times to find anything in the logs (captured via log show --info --debug) at the moment when the screen turns on. As far as I can tell, there's absolutely nothing there that might be related (there are a number of messages during the time period in question, but for all of them similar messages happen many times before, while the screen is blank.

Very weird.

I am trying to understand if the main issue is the G1 or if its a general Ice Lake issue.

For instance, would I be safer getting a 1065G7 than a 1035G1?

I am asking since I am considering an Acer Aspire 3 with the 1065G7 or an Acer Aspire 5 with the 1035G1. They are exactly the same price right now with similar specs so it would seem the 1065G7 is a better choice but I wonder if it will also make hackintoshing it easier?

The best option would be a 1065G7 laptop with no dedicated gpu (eg: an MX 250/MX 350 etc...).

I was experiencing the same issue. My screen wasn't completely black but extremely dim (essentially my brightness slider was at minimum). Screen would go normal brightness after ~4-5 minutes. The issue was an incorrect SSDT-PNLFCFL.aml. I followed the instructions here to find that my ACPI path was PCI0.GFX0. But the SSDT I had downloaded was for PCI0.IGPU. I compiled the sample SSDT given on this site and put in my ACPI folder and the back lighting issue was solved. Here is the correct SSDT for the GFX0. I have a Dell 5593, non-touch 1080P display with 1035G1.

SSDT-PNLFCFL.aml

EDIT: Well that lasted about a day. Now it has reverted to being dim for the first 4 minutes. Occasionally it will be fine from the start. No changes being made, just rebooting...

I'm on a hp x360 spectre aw0023dx, 1065g7 with 4k oled screen.

tried 528A and all other device id, no acceleration.

with

<string>-v alcid=3 -igfxcdc -igfxdvmt -cdfon</string>

it wont boot into system, just reboot on iGPU setting up.

But I can see 3D rendering log in the bootlog.

Any suggestions?

Your config.plist is invalid (no value for the ACPI/Add/Comment key), Xcode refuses to open it at all.

For those who have problem with sleep (wake is not working at all, only reboot will help and also got panics about DC9/DC6 - here is the solution: https://github.com/acidanthera/bugtracker/issues/1207

Try to use bootargs -noDC9 or -nodisplaysleepDC6 (in my case -noDC9 worked well, so i didn't test the second one, but i saw guy, who have used the second one too and it's worked as well as first one)

Make sure that your usb mapped correctly, plus that's might be usb mouse wake-up

Btw, i don't no if that method working correctly on G1 graphics, because afaik you have problem with brightness glitches. So that's might be the problem.

If you have G4/G7 graphics - you can try to test it with other framebuffers. Default one for Ice Lake which is mentioned in Dortania docs is not working properly for sleep/wake, it's unstable.

i have no problem with Big Sur beta 10. Working as well as Catalina.

UPDATE:

Got the glitch of Apple logo to disappear after half of progress bar is done - after update to Big Sur 11,0,1 beta that's seems to be fixed. Now Apple logo not disappearing until progress bar fully loaded, after that i got black screen for 5-7 seconds and login screen appear. that's might be still strange, but something changed, heh

I have G7, i'll try to change others...

About USB map, i haven't find how to do correctly, with USBInjectAll type c port didn't worked well... And i haven't usb mouse...

Hi @Austere.J,

I found someone that said have temporary fixes the black screen after boot issue here https://github.com/dortania/bugtracker/issues/17#issuecomment-718727817 . I've been tested on my device (1005g1) and it works but it looks like the brightness is dropping.

Thank you

Hi Guys,
I need your support for correct brightness.

I use the ID 538A0000 under i7-1065G7 (Lenovo S340-15IIL IceLake with MacBookPro16,2 Smbios)
SSDT-ALS0.aml in use = ambient light works.
SSDT-PNLFCFL.aml (_SB.PCI0.GFX0.PNLF) in use = PNLF works.
USB is patched = works.
with bootargs -noDC9, sleep also works to.
Nvram works, also retains the brightness level that was set last.

well, on windows it's much brighter.

when i starting MacOS shortly before IGPU initializes it dims a little, which is also the maximum brightness of the screen.
I can control with the buttons minimal and maximal, no problems.
when I go to sleep and wake up it is suddenly much brighter, like on windows.
Otherwise I couldn't find any negative symptoms.

How can I achieve that it has the same brightness level as windows without sleep and wake?
Can someone help me with this?

Thanks and greetings Coban

Using this ig-platform make my cursor issue come back and vram drop from 3gb to 1.5gb. previously i've been fix the issue by set stolenmem and unifiedmem but doesn't work with this ig-platform.

Did you get this issue on your device?
