Baio77 Posted October 5, 2021 Share Posted October 5, 2021 I think the best solution is to use SSDT, in any case both Opencore and Clover Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 5, 2021 Administrators Share Posted October 5, 2021 SSDTs are more flexible and to the point. DSDT patching is now kinda deprecated and seldomly used. Link to comment Share on other sites More sharing options...
djuby Posted October 5, 2021 Author Share Posted October 5, 2021 Thank you guys. I will go the SSDTs way and will post the results. @Baio77 I will use your SSDTs as reference and will make my own for my system. Link to comment Share on other sites More sharing options...
djuby Posted October 7, 2021 Author Share Posted October 7, 2021 Hi guys, Here is my update. Following this guide (https://dortania.github.io/OpenCore-Install-Guide/config-laptop.plist/coffee-lake-plus.html) I created all required SSDTs. System boots fine. Still no full trackpad functions (works just like a normal mouse, no gestures). I tried to use VoodoI2C+VoodooI2CHID kexts, but I get kernel panic. So right now I'm using just VoodooPS2Controller kext. Brightness is not working (no brightness slider in settings, and brightness keys are not working too). Sleep is not working. When I force it to sleep, it doesn't actually go to sleep - screen goes blank, but the system is still on. When I try to "wake" it up - nothing, just blank screen. I have to reboot. I am attaching my current EFI folder, original DSDT, ACPI Paths file (for some system devices). Any ideas and suggestions will be greatly appreciated. Best regards.

Baio77 Posted October 7, 2021 Share Posted October 7, 2021 post ioreg please , use this SSDT . The choice of SSDTs is not accidental, I know DELL machines and all these SSDTs are needed. add rename in config for SSDT GPRW and SSDT XOSI. SSDT GPRW and SSDT PMCR they help the laptop sleep although this also depends on other factors Archivio.zip For the trackpad as well as Ioreg I would need to know the precise model, if ALPS are developing a Kext in these days, but now gestures work, only the trackpad buttons are missing Link to comment Share on other sites More sharing options...
djuby Posted October 9, 2021 Author Share Posted October 9, 2021 Here is my IOReg. I added rename for SSDT XOSI, but there is no patch rename for GPRW. Where do I get this? Attaching config.plist as well. Best regards. IORegDump.ioreg.zip config.plist.zip Which device is the touch pad? Searching any of the DeviceIDs does not tell who's the manufacturer. And here are two more screenshots from AIDA64 on the touchpad device. Link to comment Share on other sites More sharing options...
Baio77 Posted October 9, 2021 Share Posted October 9, 2021 This rename for GPRW Ioreg is not good, wrong SMBios 16.2 is for Ice Lake CPU, use 16.4 or 16.1 https://drive.google.com/file/d/10EKHFG8WbqNusmLfdik7mWLnKSFIZj7j/view use this file ACPI and Kext Pass the EFI Link to comment Share on other sites More sharing options...
djuby Posted October 10, 2021 Author Share Posted October 10, 2021 Thanks Baio77. I've changed the SMBios to 16.4. Updated the ACPI and Kext as per your file. Removed VoodooI2C and VoodooI2CHID kexts. I still get kernel panic when using them. Still no brightness control. Attaching current EFI. Best regards. EFI.zip ... and here is the IOReg.
