    in E5xxx

    Posted

    EFI OC 0.9.0 use OCAT to manage the Config.plist.

    Try this EFI, Corrections:
    Fix SSDT PNLF 
    Add Kext SDReader
    Fixed Kext USBPort not loading as it is done with SMBios Macbookpro 11.4
    Removed Useless Kexts ECEnable is not needed on DELLs, it should still see the battery
    PciRoot(0x0)/Pci(0x3,0x0) is wrong contains strings for IGPU.

     

    Test in USB if start ioreg.

    I advise you to compare each section of the config because I changed various things.

    Latitude 7400: Troubleshooting Thunderbolt3

    "Thunderbolt Boot Support" Disable.

     

    Open ioreg search for RP05 (here you find your TB3) See that in these 2 Ioregs you have the patch active. So SSDT-TB3 works, I just need to modify it. I leave the modified EFI to test.

    Try this, ioreg if start, you need to save ioreg after connect type-c hub and TB3 dock. Thank you.

    Here's the OpenCore EFI for my Dell Latitude 7400. Everything works great. macOS Monterey 12.6.3 configured for Intel WiFi/BT:

    Dell 7400 OC 0.8.9 Monterey IntelWiFi

     

    If you have BCM card remove the kexts Airportitlwm, IntelBluetoothFirmware and BlueToolFixup. Ventura tested and not working well with Intel 9560NGW, if you have Intel 8260/8265 it will work flawlessly. Enjoy!

     

    My specs are:

    • Whiskey Lake i7-8665U CPU
    • Intel UHD 620 graphics
    • 14" FHD IPS touchscreen
    • 16GB DDR4
    • Realtek ALC295 Audio
    • Intel 9560NGW wireless

    If you want to try this EFI I fixed some things, from ioreg I see there is to fix the TB3 if this EFI starts ioreg and then I fix the TB3.

    Here in this repository is the example for patch TB3 , it works hotplug and sleep\wake. Obviously SSDT-TB3 must be adapted to the TB3 in use.

    Thanks for the replies and I have a few questions: Patch stolenmem solves the DVMT problem in theory, this determines whether the PC boots or not. So I think the problem is elsewhere as logic. Much more likely a connector issue, I think. I would like to extrapolate as much information as possible and try to understand the problem and actually determine NOT compatibility with Hackintosh. For a complete debug I add kext debug in the traditional efi and related botargs??? Here I extrapolate info on video connectors???? Thanks for the valuable info.

    For trackpad check the pictures in this reposity, set as in the picture and try https://github.com/Baio1977/DELL_VOSTRO_5501-ICE-LAKE/blob/main/Screenshot/touchpad.png

    For WI-FI use kext for Monterey https://github.com/OpenIntelWireless/itlwm/releases/tag/v2.1.0  and BT  https://github.com/OpenIntelWireless/IntelBluetoothFirmware/releases .
    Don't use this kext on Monterey or higher IntelBluetoothInjector.kext.

    Use this kext for Monterey+ BlueToolFixup.kext

    Latitude 7280: Problem with backlight control

    in The Archive

    Posted

    The problem surely depends on the ACPI of your DELL, in this case the DSDT. Here in the code is the explanation:

     

    //
    DefinitionBlock("", "SSDT", 2, "OCLT", "OCWork", 0)
    {
        External (_SB.ACOS, IntObj)
        External (_SB.ACSE, IntObj)
        
        Scope (\)
        {
            If (_OSI ("Darwin"))
            {
                \_SB.ACOS = 0x80
                \_SB.ACSE = 0 //ACSE=0:win7;;ACSE=1:win8 
            }
        }
    }
    //EOF

     

    This you might try to vary

     

    ACSE=0:win7;
    ACSE=1:win8

     

    In SSDT single is Zero set, you have to try with One
    https://github.com/Lorys89/DELL_LATITUDE_7280/blob/main/EFI/OC/ACPI/SSDT-DELL-LATITUDE-7280.dsl 

     

    Scope (\)

    {

    If (_OSI ("Darwin"))

    {

    HPTE = Zero

    SDM1 = Zero

    \_SB.ACOS = 0x80

    \_SB.ACSE = Zero

    }

    Test this EFI if start ioreg https://drive.google.com/drive/folders/1ZNwe7Rw2ZXV0fbzpnRq43uhnUIDqp6Nh?usp=sharing
