Legacy-Kexts VS VoodooPS2

Try adding SATA-unsupported https://github.com/khronokernel/Legacy-Kexts/blob/master/Injectors/Zip/SATA-unsupported.kext.zip

I would guess SATAUnsupported.kext, but you should check here and make sure you've disabled anything unsupported, such as IRRT, hardware, etc. Again, I have no idea what your hardware and OC configs look like. Maybe start fresh, and open a new thread? You mentioned using the same files for your Clover and OC configs, and can personally tell you this rarely works right.

SATA-unsupported

For Catalina, You should use this kext instead SATA-Unsupported(opens new window)

Thanks for the tip, I tried installing SATA-unsupported.kext and AHCIPortInjector.kext

ATAPortInjector

I took a look at your EFI, and I don't see any obvious errors in the config.plist. Concerning the ACPI, I don't think a valid EC is required in macOS prior to Catalina 10.15; thus, SSDT-EC is unnecessary. Concerning the Drivers, I don't think Ps2KeyboardDxe is required. Also, why use VBoxHfs-32 instead of HfsPlus32? I am curious as to where you got most of your kexts; USBInjectAll only works on El Capitan 10.11 and above, and I don't think IOATAFamily nor SATA-unsupported are required for your laptop; does your laptop even support AHCI or SATA?. AHCIPortInjector and VoodooHDA, I'm not sure about (for the latter, I think you should be using VoodooHDA-FAT). The others look fine, though.

Keyboard and mouse nipple - VoodooPS2Controller

VoodooPS2Controller (For the trackpad it has to be modified) Look at the guide

I use Itwlm/AirportItwlm v2.1.0 and VoodooPS2Controller v2.2.9 (haven't gotten around to updating).

Keyboard (VoodooPS2), TouchPad (w/gestures) and TrackPoint (VoodooSMBus)

Questions/Basic Troubleshooting - Did you determine which type/hardware/rev your Touchpad is? Did you check in the BIOS if it's actually HID, or PS/2? You stated HID, but I see a kext entry for VoodooPS2Trackpad as well. Did you read the guide over on the VoodooPS2 page?. You may or may not have to edit the config inside the VoodooPS2Trackpad.Kext (hardware dependent, and not always necessary as of 2.28). Read carefully, there are known issues with Trackpad Gestures. Do you also have a Touchscreen as well, and is it working? (I see Voodooi2c, assuming there's no other i2c devices) Did you do Clean Snapshot after loading your Kexts/ACPI?? OCValidate?

I also tried VoodooPS2 without success.

you need to add voodoops2 kext to EFI Kext folder https://github.com/acidanthera/VoodooPS2/releases

I've seen https://github.com/acidanthera/VoodooPS2 but it only works on Hackintosh's I think? I tried installing the ktext on my genuine Macintosh but to no avail.

Currently using acidanthera / VoodooPS2
