Dell Dude Posted March 9, 2020 Author Share Posted March 9, 2020 Alright, so I finally got my 1820A card working fully in macOS, but can't for the life of me get the trackpad working. I got 1820A working by finding my device with IORegistryExplorer: GP10 - 1D,1 with the 14e4,4353 injection If anyone has any tips on getting the trackpad working on these 3400 Series laptops, that would be greatly appreciated! Here is my debug output. debug_29620.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 9, 2020 Moderators Share Posted March 9, 2020 Remove VoodooI2CSynaptics.kext and add VoodooI2CHID.kext. You might need to reboot a few times before it'll work. If that still doesn't work, you could remove VoodooI2C and VoodooI2CHID and SSDT-I2C.aml and just use PS2 kext. Link to comment Share on other sites More sharing options...
Dell Dude Posted March 9, 2020 Author Share Posted March 9, 2020 Tried this and rebooted several times. No dice. Unfortunately, removing I2C kexts/table did not work either. debug_24981.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 9, 2020 Moderators Share Posted March 9, 2020 I see the problem. Restore the 2 kexts above. Replace the Config and SSDT with the attached. 3400_I2C.zip Link to comment Share on other sites More sharing options...
Dell Dude Posted March 9, 2020 Author Share Posted March 9, 2020 Thank you for continuing to help me troubleshoot this issue. I restored the two kexts and replaced the config and SSDT files that you attached. Still no trackpad improvement yet. Question: should I be using GenI2C to patch my DSDT file? debug_20071.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 9, 2020 Moderators Share Posted March 9, 2020 I have never tried it, but give it a try to see if it works better. Link to comment Share on other sites More sharing options...
