  • Administrators

it's a Latitude 5491, not an E5491 which does not exist...


Qualcomm card not supported -> to be replaced by a supported model.


For the rest, your Clover setup (config & kexts set) is very messy.

  • ACPI renaming contains stuff for Z390 desktop motherboard.
  • Your Clover Kernel & Kexts patches section contains all sorts of irrelevant and inappropriate patches (eg: BDW + SKL + KBL patches). Remove those
  • You selected MacBookAir8,1 SMBIOS, i.e. that of an Amber Lake platform with UHD617 graphics Amber lake model when you have Coffee Lake CPU with UHD630 graphics. Use MBP15,2 instead.
  • Graphics: you inject layout id 12345678, i.e. a fake layout used for troubleshooting graphics in VESA mode. You cannot get any graphics acceleration with this. Replace this fake layout value by one of a UHD630 layout or don't inject anything in Graphics section and, instead, inject any required properties such as layout id (eg: 0x3E9B0000) and iGPU id (but native id should be Ok) in Devices section for device PciRoot(0x0)/Pci(0x2,0x0). Then rely in Lilu + WEG kexts.
  • Get rid of all those XHCI and SATA kexts, they're not required
  • TouchPad will undoubtedly be I2C so you'll need to add the VoodooPS2 I2C kexts and probably the I2C SSDT tables too.

Refer to existing Coffee Lake/Latitude 5490/Latitude 5400/Latitude 7490/Latitude 7400 threads for guidance and do a search on UHD630.
