You added the kext but did not enter the info in the Config file. Unlike Clover, you need to manually add each kext + plugin (if available) to the Config file in order for it to load. Here, added it for you, give it a try. config.plist.zip

You should be able to run Catalina with Clover 5119, no problem. Post your Clover folder if you need assistance with the rest. Can't help much without knowing what you have and what you'll need to fix those issues.

I don't see you added RealtekRTL8111 in the OC folder or IOReg file. You can disable IntelMausi since it's not needed and replace it with RealtekRTL8111.kext

@pasuri With a quick googling would've given you the result. Here's one https://raw.githubusercontent.com/black-dragon74/OSX-Debug/master/IORegistryExplorer.zip

you can try latest OC files here https://osxlatitude.com/forums/topic/9179-dell-latitude-e7x70-installation-guides-uefi-only-clover-and-opencore/?do=findComment&comment=104256

remove this from the boot arg under NVRam in the config file -igfxvesa

Good luck with Clover, support is not so good with Big Sur at the moment.

Yes, to resetting the NVRam on any changes

Check OC Picker, do you see an option for Install MacOS...? Looks like the installation didn't complete, from the screenshot it shows kernel = 19H15 = Catalina. Big Sur kernel = 20xx

Post IOReg file using this app Launch, save, compress and attach it here

Post your OC folder + IOReg file using IORegistryExplorer.app There're no ethernet patches hard coded in the SSDT's if you're using my OC files

try this config config.plist.zip

ok, give this one a try config.plist.zip

Post your OC file + IOReg file using IORegistryExplorer.app

Ok, try these. VoodooPS2 is for Elantouch but it works for me E7470. If that also not work, then ApplePS2 will be your last resort. Make note of the plugins when you add them one at a time. PS2Controller.zip

Try this one, made a modification VoodooPS2Controller.kext.zip

You need to disable it in the Config file as well, not just removing the kext. Also the 1revenger1 voodoo has less plugins, so make sure to edit the Config as well, disabling voodoops2mouse.kext should be enough

Disable or remove SMCDellSensor.kext //fix touchpad else replace Voodoo with this Alps version https://github.com/1Revenger1/VoodooPS2-Alps/releases Change audio layoutid to 11. That should fix audio and HDMI

Remove the Intel wifi / BT kext should bring the folder size down

@Skyfox61 post your OC files + IOReg file using IORegistryExplorer.app

Please post IOReg file with IORegistryExplorer.app with HDMI monitor connected What version of VoodooI2C does it have?

try my files here For external HDMI video, close the lid for a second until external monitor becomes primary. Then open the lid. or sleep the computer 1st, then wake it up. HDMI video will work correctly If you have Intel wifi /BT, replace / add appropriate kexts which you seem to have already

Try this, replace the Config and add the SSDT* to ACPI folder 5590_touchpad.zip

@NTHT1MD Looks like it might be a graphics issue. So in the boot arg, add this to get the installation going. Remove it after installation -igfxvesa Here's the edited Config file from your attachment with the boot arg added config.plist.zip

Can you post your DSDT?
