Why did you remove the VoodooI2C kexts? Try this, replace Config & DSDT/SSDT Add all kexts to /EFi/Clover/kexts/Other but AppleBacklightInjector.kext goes into /L/E Repair permission and rebuild cache 7480_catmater.zip

HD520 or HD620? PS2 is for the keyboard. I2C is for the touchpad Your DSDT was missing the GPIO Controller patch

Made a couple of changes to your DSDT, see if touchpad works. If not, try replacing VoodooPS2Controller with the attached VoodooPS2Controller.kext.zip DSDT.aml

Yes, but some might not and need additional patch. What brand is your NVMe drive?

The files you're using is not for the touchscreen model probably. Replace the Config.plist in /EFI/Clover Replace the DSDT/SSDT in /EFI/Clover/ACPI/Patched From the attachment here

I said to install over it, not clean install. Anyway, from the generic EFI folder, copy HFSPlus.efi from Clover/drivers64UEFI to the same directory in the EFI partition If you want the Latitude theme, just copy the Latitude folder from the themes folder over to the same theme folder in the EFI partition.

Did you install Clover to the SSD? Reboot with the USB installer, select the installed drive. Once you get to the desktop, install Clover, copy the EFI folder to the installed drive from the USB

Sorry I haven't updated those files. Go ahead and install latest Clover over it to update the files and try again. I'll update that soon, but those files should work fine if your MacOS is 10.1.3.3 and older.

The files in /EFI/Clover/drivers64UEFI are data 2/09/2018 so it does not reflect the latest Clover 4439 which should show today's date. Do you have UEFI and AHCI set in the BIOS?

If you're installing HS 10.13.4, you'll need the latest Clover (minimum 4428).

SSDT-PNLF.aml is for Brightness. The generated SSDT.aml goes in ~/Library/ssdtPRGen You'll have to manually copy it to /EFI/Clover/ACPI/Patched

follow steps 7 and 8 of post install

The recommended cards are DW1560 and DW1830, not DW1820A

Follow post installation from guide here https://osxlatitude.com/topic/8506-dell-latitude-inspiron-precision-vostro-xps-clover-guide/

Add HFSPlus.efi to /EFI/Clover/drivers64UEFI

Use this bootpack, goes into /EFI/Clover

Clover guide. Bootpack on post #2

sounds like a bad USB installer. Try another USB drive

set BIOS to: 1 XHCi hand off = Enable 2. VT-D = Disabled

It's Fn+F3 & Fn+Insert to control brightness. If it's not working, then you might just need to repair permission and rebuild cache

Hmmm, though the hot patch for HDMI is set in the Config, but it's not reflecting in the IOReg. Try this, in /EFI/Clover/kexts/Other, remove IntelGraphicsDVMTFixup.kext and AppleALC.kext Add AppleHDA_ALC292.kext to /L/E Run the permission.sh again. Look in the output, make sure you see AppleHDA_ALC292.kext in the cache If not, run it again until you see it. Reboot, check again for HDMI audio AppleHDA_ALC292.kext.zip

Follow instructions from here to debug issue gen_debug -sysprofile

Under Sound preference, do you see the option to switch to HDMI audio? It's not automatic

Can you please just edit your post with new findings instead of new posts? Did you do the post install? 7. Copy kexts from /EFI/Clover/Kexts/Other/LE to /Library/Extensions Repair permission and rebuild cache Use the permission.sh script to do the above To control brightness, use Fn+F3 and Fn+Insert You could try installing Karabiner-Elements app to reset the Fn key
