Fantastic work! My touchpad works well now.

But...My BCM94352 broken after using your kexts.

I tried to pull my old BCM drivers to kexts but it did not work maybe as FakePCIID cannot be load...

Hello Jake,

thank you for the precious input from above, I have understood how it works and did all the steps that are required for the I2C Touchpad.

a) Extracted and fixed DSDT ( so I get a success compilation )

b) Added the patched from VoodooI2C

c) Installed the VodooI2C kexts

BIOS-Version: 1.7.2 (11/26/2018)

I have also provied screenshots with information about the TouchPad (Windows Device Manager: Hardware-IDs, etc) and also IOReg-Screenshot with what I can see under Mac.

  

Can you please have a look in the DSDT and give me some input, for some reason I feel like I am missing smth

Hi, i did not pay much attention on I2C kext, but I know sometimes it could cause a panic. And on the Alex's github repo, some people raised this kind of issue, but alex said he is too basy now, so if you cannot solved it, the things we can do maybe just wait...

Then you should user the press on touchpad to replace the buttons.

Hi all, update: USB audio seems to be fine via Dock, as is the USB-C nic in my dock. Driver from realtek site was necessary as 8153 is not part of AppleUSBECM afaict.

The onboard NIC also works fine using  i219 driver from multifail. I did have some trouble getting onboard to "built-in" status but the EFI string added to config.plist seems to be doing the trick.

 

I seem to have broken my onboard keyboard however... Yes the trackpad was jittery but now neither work. Not sure what I did to hurt it.  EFI attached.

I will help u to try this this week.

BTW, have you meet any panic about I2C kext? 

Thanks! In order not to disturb your communication with @Jake Lo, I will ask for cpu frequency details after you solve your problem.

Update: I think the reason is ssdtPRGen.sh, in this repo, there is no info for i5-8250u, i will try to find the related info and run it.  

Update +: Generated ssdt.aml and place at paych,  it did not work, the CPU frequency also maintain at 3.1G. 

Another problem is about CPU frequency, I used Inter Power Gadget as a monitor and found the frequency is maintain about 3.1Ghz, which may caused the fan always rotating fast.

Very cool, thank you, huge improvement!

 

Graphics and HDMI now good. Will test USB-C shortly.

 

USB atheros NIC is missing from USB hub now. Is this a PCI remap issue?

Trackpad is also working, however in a way I'd describe as jumpy.  How do I tune this?

 

 

7490 too, maybe use the same setting and ELF file.

Perfect sleep and graphics.

Not work:

   Trackpad Jumpy too and the click buttons did not work.

   Cannot use a earphone, but the built-in speaker is OK.
