Administrators Hervé Posted December 17, 2023 Administrators Share Posted December 17, 2023 In all likelihood, it's USB related. Post your full hardware specs and bootloader's EFIif you want support. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted December 17, 2023 Administrators Share Posted December 17, 2023 Those specs aren't much helpful to sort out your predicament, are they? What about the touchscreen? As for your zip file, it's not downloadable... Link to comment Share on other sites More sharing options...

Administrators Hervé Posted December 19, 2023 Administrators Share Posted December 19, 2023 Either your Touchscreen is not USB-based in which case it could be I2C or PCIe based and you'll need an adequate kext, or your USB ports are not properly mapped and the device is not properly detected. Can you post a zipped IOReg extract? Link to comment Share on other sites More sharing options...
