oyko Posted December 14, 2020 Share Posted December 14, 2020 Hi, I have Dell Latitude 7480 i7 7600U, Intel HD 620 Graphics I have installed Big Sur 11.0.1 (20B29), bootloader OC 0.6.4 everything works except Sleep and "No Trackpad Found" on system preference. Work 2 fingers up and down scroll, 2 fingers tap, 1 finger tap. I use VoodoI2C, VodooI2CHID, VoodooPS2Controller. Any suggestion for solutions? Is trackpad detected on System Preference? Thank you Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 14, 2020 Moderators Share Posted December 14, 2020 @oyko No because Alps I2C touchpad are not supported by those kexts. You'll just have just those basic function and detected as a generic mouse. Link to comment Share on other sites More sharing options...
oyko Posted December 14, 2020 Share Posted December 14, 2020 Oke thanks for the info @Jake Lo, Yes mine only got function 1 tap, 2 tap fingers and up down scroll. Anyway is it possible to make it works (multi gestures) ? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 14, 2020 Moderators Share Posted December 14, 2020 I'm not a developer, so if you know how to port drivers from Linux, then give that a go. As I said, Alps I2C is not supported so no gestures. You could try to research if you could replace the ALPS I2C with a Synaptics I2C touchpad since synaptics is supported.
