ioncatana Posted February 5, 2019 Share Posted February 5, 2019 Hi JakeLo, thank you for your fast reply. I have tested your boopack and here are the results: a) I get kernelt panic in VoodooI2C.kext b) I replaced the kext's with mine and I could boot into OS (Problem: TrackPad is working very poorly | no buttons from trackpad are working and the sound isnt working) c) I have taken a few of your patches from the config and the ACPI-contents The state is still the same: + Sound OK, GPU OK (FullHD), Bluetooth, Keyboard, USBs - Trackpad isnt working / and the buttons from Trackpad are not working - WiFi (will replace it with an atheros or smth) --- Info of my Trackpad: Alps Virtual HID HID\Vid_044E&Pid_1212&Col01&Col01 I2C HID Device HID\VEN_DELL&DEV_081C&Col01 HID\DELL081C&Col01 HID\VID_044E&UP:0001_U:0002 HID_DEVICE_SYSTEM_MOUSE 7490_EFI_CLOVER.7z Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 5, 2019 Moderators Share Posted February 5, 2019 You can try contacting the developer of VoodooI2C. I don't have any hardware with I2C touchpad so...you'll have to do some homework. https://voodooi2c.github.io/#Installation/System Requirements https://gitter.im/alexandred/VoodooI2C Link to comment Share on other sites More sharing options...
ioncatana Posted February 7, 2019 Share Posted February 7, 2019 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 DELL7490_DSDT_I2C-Touchpad-Info.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 12, 2019 Moderators Share Posted February 12, 2019 No need for the DSDT as the hot patches plus SSDT-I2C.aml + SSDT-XOSI.aml are already patched for it. The problem is perhaps the kexts does not support your hardware yet. Link to comment Share on other sites More sharing options...
micheajp Posted March 5, 2019 Author Share Posted March 5, 2019 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. 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. EFI.zip Link to comment Share on other sites More sharing options...

Update +: Generated ssdt.aml and place at paych, it did not work, the CPU frequency also maintain at 3.1G. Mine is running low and ramping properly. @persistz if you try the efi I just uploaded do you have the same problem? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 5, 2019 Moderators Share Posted March 5, 2019 @micheajp why do you use a Desktop SMBIOS over a laptop? Link to comment Share on other sites More sharing options...

micheajp Posted March 5, 2019 Author Share Posted March 5, 2019 I still don't know what to look at deeper for the USB-C DP video issue. Any ideas? It's detecting my monitor incorrectly. Link to comment Share on other sites More sharing options...
