That was easy do to, I feel useless... I worked, thanks!

How one can do it? Thanks in advance.

I moved to OpenCore 0.6 and the trackpad only jumps from time to time. BUT I have found something interesting: in the OC picker, where you select the operating system, the mouse moves AND the physical buttons work. Later in Catalina/Big Sur buttons don't work. Why could be that? Summoning @Jake Lo and @Hervé in case they know the reason.

Hi all, I have been using Herve's EFI files successfully with Catalina. The voodooI2C/HID files for his Latitude 7490 worked like a charm. I am moving to OpenCore and, while everything works, the trackpad shows some delay between my fingers movements and the trackpad arrow. Is this happening to anyone else? I attach my EFI folder. Thanks. EFI.zip

I did not update anything, as it is working fine for me.

No idea, sorry. If you boot in verbose mode, what message do you see?

It does not work, you have to buy a new one

it is working for me, with a DW1560 card. Do you use the stock one or have you installed a Broadcom?

Here you are! https://www.dropbox.com/s/39m05nmzx4qe1p3/ EFI Working OCT19.zip?dl=0 Let me know if it works.

Micron 1100 SSD 512Gb

Here you are: https://drive.google.com/open?id=1i0v_aY23VgCWYTKsCOR0gZeIe1Cn6fz_ I have the factory SSD, I changed nothing on the BIOS, as I remember and I did not update the BIOS.

I have the same laptop and used the manual Hervé linked, everything worked perfectly, except the trackpad buttons.

Magically, It worked again. I tocuched nothing, but now it works afters some restarts...

Hi again, I updated to 10.14.5 and trackpad stoped working. Does your system work?

You got them from me The thing is that there is some lag with the Dell trackpad, but not with the Magic Trackpad. I tried your 7490 guide, but I get a KP when booting.
