Hey. I've tried again add the device-id as recommended but that ends up in a black screen so I had to remove it to save the IOReg file as you requested. The EFI folder you see reflects that change. Attached. Thanks in advance EFI.zip + IOReg file IOReg.ioreg

Hi @muttonhead411 Regarding the keyboard issue is fixed and everything seems fine. Adding the device-id as suggested makes the OS not bootable. So I reverted to where it was.

Hi, Keyboard is working now. Also for graphics, I changed device-id as seen on @Hervé post but no luck. Thanks,

Ok, I can confirm after typing exactly as mentioned works perfect Many thanks,

The ig-platform-id didn't really match with what you said. The SMBIOS seems to have changed properly. But the graphics are only in VESA mode. I'm using OpenCore Configurator and the settings I had under DeviceProperties were, AAPL,ig-platform-id - DATA - 09001659 device-id - DATA - 16590000 I changed to, AAPL,ig-platform-id - DATA - 09001619 device-id - DATA - 16190000 Is it correct?

Hi, I’ve used this EFI folder to perform Big Sur Beta 11 installation and seems to be almost perfect. I notice a bit more slowness compared to Catalina. Could be because it’s Beta or either there is some issue because I experience very slow boot. Also important to refer I have HD 520 instead of HD 620. Thanks in advance,

It works, fully working hackintosh now Many thanks @Jake Lo Just in case someone finds the same problem sometime, while I was doing this change at the same time I was reinstalling CoreDisplayPatcher but I don't think that was the fix as yesterday I had already tried that and no result.

Few more info, BIOS updated to latest version. Setting remains and also possible values. Strange thing is that in Clover the resolution is ok, only goes 16:9 on macOS. Also the audio output is detected. Any more ideas?

I confirmed it was set to 0x4 before changing it, and it was. Changed to 0x2 same result unfortunately.

I figured that and I did it first. It was 0x01 and now after running the command it's 0x04. macOS Booted but still no correct resolution

Got it. Just do double check, the option I should consider is the 0x795 if I got it right, or? Then change it to 0x4 with "setup_var 0x795 0x4"

If I understood correctly should be 0x3 anyways right?

Thanks. Unfortunately it didn't worked. I guess next step is what you mentioned. A quick search showed this post from you a while back. Is this up to date or you recommend something else? Also, you think latest Hirens with WinPE would be ok to run this guide?

It turns out the USBs not showing up was an issue related to having already a pre compiled SSDT, after doing everything from scratch all works fine. I can even get ethernet from WD15 and DA300 docks from Dell. Also hotplug works fine. Many thanks. The UltraWide monitor is still not working. I tried with -cdfon but no luck. I saw I have enable-hdmi20 with value (01000000) tried -cdfon with and without that property and still no correct resolution. Again this is connected directly to the notebook, no docks or adapters.

I will try the -cdfon arg when I have the screen again later today. However the USB part is getting tricky. I've checked what are the ports on the laptop and found which ones should be kept enabled or not. The question is I never see the USB-C ports, either hot plugged or plugged during boot.

Dell WD 15. Any guide you would recommend for that? Also any chance of getting the ethernet port active? Another strange thing that I just found is that UltraWide screen connected directly to HDMI port is not showing correct resolution. It seems that HDMI 2.0 is “not enabled”.

I did search and all those EFI folders would end up on KP as well so I thought starting with clean EFI folder. Anyhow, I've used @catmater v4 EFI folder and same KP, I realized the iGPU was different so -igfxvesa allowed me to boot, install and look around and see I had to adjust the config.plist for the HD 520 instead the HD 620. Everything seems to be working fine now. One question related to USB Ports, I see if a docking station is connected to USB-C port, the screens do behave like regular MAC but the USB and Ethernet ports seem dead. Ethernet seems obvious most likely because there is no driver but the USB ports, is it necessary to map the USB ports with dock attached? Or maybe there is some other way?

Hello everyone, Trying to install macOS Catalina 10.15.2 on Dell 7280 and always get stuck on a "++++++++++++++++++++++++++++++++++++++++++" verbose screen. Right now this is out of the box Clover (most recent) EFI folder with only the options mentioned on the general guide for Catalina also added the ECDV to EC DSDT patch but made no difference. Kexts are: AppleALC FakeSMC Lilu WhateverGreen Anyhow I'm attaching the EFI folder. Thanks, EFI.zip
