  1. It's totally strange that our trackpads are responding differently under virtually the same conditions. Can you confirm if VoodooI2CHID is loading properly (I don't see it in your screenshot)? Do we even have the same trackpad? The hardware ID for my trackpad is DELL081C. If we have the same trackpad then my thoughts jump to the BIOS configuration / version. I flashed mine recently so should be on the latest version. Or else, could it be that our trackpads are flashed with different firmwares? I tried the Swung boot loader which you linked - it seems to perform exactly as Hervé's does - albeit this occasionally occurs: "but it would occasionally cut off while dragging or using the cursor, which is more frustrating (the buggy and jumpy trackpad bug dissapeared though). " however it is very slight for me (once every 10 minutes, barely noticeable). As an aside, what did you do for wi-fi? Did you replace your internal card?
  2. Hey Fuzeless, Are you using OpenCore as I was, or Clover or some other bootloader? I've resorted to using clover for the timebeing as I'm exhausted with trying so many different options and getting nowhere. The trackpad works perfectly under clover using the bootpack I linked to previously. OpenCore is another story entirely. I have tried so many different configurations at this point, such as different versions of I2C and I2CHID; +- XOSI +- GPIO +- XOSI + GPIO + various hotpatches of GPIO and XOSI +- Mojave OS +- Catalina OS +- transplanting the SSDT-I2C.aml file from Hervé's bootpack. Since my first post I attempted GPIO pinning the trackpad. According to the guide it is already very-well-pinned but I made some edits to the DSDT file to remove extra entries in XCRS section so that "Return (ConcatenateResTemplate (SBFB, SBFG))" was the only return statement. Also tried patching the dsdt with the three recommended patches but the laggy trackpad behaviour was still the same. Weirdly, if I pull-up the trackpad in IORegExplorer, while booted with clover, it lists values under gpioIRQ and gpioPin (see screenshot). These properties are not defined under OpenCore, even with the custom DSDT for GPIO pinning + patches. This seems relevant. If you're still experiencing issues then maybe it is worthwhile testing Herve's bootpack to see if that resolves the problem?
  3. Ah yes, Intel I2C does show as being loaded in IORegExplorer. I removed AppleIntelLpssI2C.kext, AppleIntelLpssI2CController.kext and AppleHPM.kext, reloaded kext cache, and sadly the problem sticks. I also tested an alternative opencore configuration using a custom GPI0, and no SSDT-XOSI file but the results are largely the same. Might try an upgrade to Catalina tomorrow and pray that will solve it.
  4. Tried this using VoodooI2C V2.14 and VoodooI2CHID V1.0 (copied from Hervé's files) which fixes the jumpy cursor problem but comes with a different problem: laggy cursor movement - which is even more bothersome and frustrating. I've also tried various other VoodooI2C versions (between V2.14 and V2.4.2) which generally result in one problem or the other.
  5. I followed the OpenCore laptop guide provided by dortania.github.io which has worked splendidly well, however I am encountering some issues with the trackpad. The cursor's movement is jumpy. When moving the cursor, or when taping to click, the cursor often jumps to a different position on the screen. Has anyone encountered a similar issue before and can provide some pointers, or has some idea of what's up here? SPECIFICATIONS: DELL Latitude 7490 CPU model - Intel Core i5 Kaby Lake-U/Y OS Version - Mojave 10.14.6 VoodooI2C - v2.4.2 VoodooI2CHID - v1.0 INSTALLATION DETAILS: Using Rehabman's hotpached SSDT-XOSI and have applied the _OSI to XOSI Rename patch to my config.plist file (see https://dortania.github.io/oc-laptop-guide/prepare-install-macos/setting-up-input-devices.html for links/details). Oddly enough, the trackpad works perfectly under Clover, using Hervé's bootpack. Is there someway of transplanting the relevant sections from this clover bootpack into my vanilla opencore installation?
