Hpbrown Posted December 6, 2020 Share Posted December 6, 2020 Hi I''ve done further testing on my Latitude 7400 which works almost perfectly except the TouchPad. When using Voodoo PS2, the TouchPad works as a mouse, buttons are functional, drag & drop OK but unfortunately not the 2 or 3 finger gestures I've tried then to test HID and follow the guide https://voodooi2c.github.io using SSDT patching: External (GPHD, FieldUnitObj) Scope (\) { If (_OSI ("Darwin")) { GPHD = 0x0F } Else { the TouchPad is now functional with 2/3 finger gestures, scrolling OK..but unfortunately not the drag & drop or buttons. is there any idea to improve this.? did I miss anything?

ShadowMinhja Posted December 22, 2020 Share Posted December 22, 2020 If anyone here still struggling, I got my 7490 trackpad working great now! I posted my EFI in this other thread which helped me resolve the issues. Hopefully since the 7490 and 7400 are really close, it might help. https://osxlatitude.com/forums/topic/13361-dell-latitude-7490-opencore-bootloader-buggy-trackpad-support-request/page/2/ Link to comment Share on other sites More sharing options...
