  1. I have 2 fingers scrolling, 2 fingers right click and mouse movement..but I can't find how to make tap to drag work. I've tried to use the accessibility options but I think I missed something. can you please describe how this is supposed to work?
  2. Yes it works. Many thanks for your support! @aaugustowskifor some reason, your EFI generates more error messages during boot than mine...This is probably because I use a Corei5, not exactly the same CPU. Have you been able to progress the TouchPad support? This is really the only last thing not fully working on my Latitude 7400
  3. hi here's my current EFI would appreciate if you have any idea how to fix the brightness keys thanks EFI.zip
  4. 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?
  5. Wondering if you have found a solution as I'm using a similar config. Also do you have the F6/F7 brightness keys working fine? thanks
  6. yes Fn+s and Fn+B work but not the Fn6/Fn7 keys from the keyboard I will try the layout-id you suggested in the boot arg thanks
  7. Hi Jack. I ended up installing Big Sur using a USB installer. WiFi, BT, TrackPad incl buttons fully working!. I'm a happy user especially after this painful install process. When you say to try the layout-id, is this in the boot args or using the device properties device injection process? I will do further testing but seems so far that the only non working parts are the brightness controls with Fn keys and audio jack. I would love to fix those but as I said, I can easily live without
  8. Hi Jack, the brightness controls with the Fn key do not work with your SSDT. I think that I can live without..thanks for trying anyway I have another issue. When launching the Big Sur installation via software update, the app starts then fails at 12min exactly prompting to reboot the system. In fact, the system doesn't reboot, it's just restarting the Finder. any idea what could cause this issue or a workaround to this install process? I've tried several times and it fails constantly at 12min Should I try to upgrade running the Big Sur installer from a Mac.?
  9. Thanks Jack. I will test this later today and report here's the IOReg file MacBook Pro.zip
  10. I manage to fix the serial issue using UpdateSMBIOSMode as Custom instead of Create (which was the default).. How to enable Fn6 / Fn7 keys to adjust the brightness controls? thanks
  11. thanks Hervé. I've followed carefully step by step. I'm booting and everything works fine. Even the TrackPad and buttons which were not working properly under Clover are now fully functional. Only issue is the About This Mac which does not seem to pick properly the model and serial number. Any obvious reason when looking at my EFI folder attached.? Also I'm wondering if the Audio solution is the best one given that the Jack does not work (but it didn't either in Clover..) Next step when system is stable to upgrade de Big Sur thanks EFI.zip
  12. Hi I’m currently using a Latitude 7400 with Catalina using Clover. i would like to upgrade to Big Sur but need to upgrade to OpenCore first. Has anyone done it already? If yes , could you please share your EFI folder ? Thx
  13. I've just upgraded to Catalina and most of my USB have disappeared. USB mouse, Bluetooth and Webcam seem to be working. Only the Touch Pad buttons are not working! I'll continue further testing and submit a debug file if needed many thanks for your help
  14. For sure I have USB issues. Any guidance to troubleshoot and fix would be appreciated . Really frustrating as everything else is working fine..Thanks in advance
  15. the problem is that I also have USB issues with this config. My USB mouse only works when connected to the Dell docking station via USB-C. When connected directly to the USB port of my laptop it doesn't work. any idea how to make the mouse work over the USB port? thanks
