Update 23-Aug-2022: Replaced SSDT-USBX.aml; Removed _DSM patch from Clover pack; Fixed freeze seen during OS upgrades. Update 15-Aug-2022: See build notes, efi for clover 5148 and opencore 0.8.3 are included. Same ACPI and currently released kernel extensions were used for both bootloaders. I have successfully ported Ventura onto a Latitude 7480, with recent Clover and recent Opencore bootpacks. Both are attached here. The bootpacks work for 10.14, 10.15, 11, 12 and 13. 10.14 and 10.15 do not have the point stick working, though. Several challenges for this port: 1. Kabylake CPU, Skylake era support circuits 2. PS/2 keyboard, I2C trackpad and dual point stick. 3. Letting go of assumptions and old techniques. Still working on that! I apologize in advance if I failed to note your contribution. I want to thank all the people who have made the pieces and provided information that makes this work so well.

@Hecatomb A word of advice when you want to post a copy of your EFI folder: remove the itlwm kext(s). Your EFI has no less than 4 x different copies of it, totalling in excess of 64MB ! You don't need to post that. 8086:15d2 is an Intel TB3 controller; can't say why it gets registered as an ExpressCard in Ventura. No idea what that 2nd PCI device listed as XHCI controller (i.e. USB3 controller) really is, no visible PCI ids. You were asked for a SysInfo extract + an IOreg extract but so far...nothing. I presume previous macOS versions did not register such hardware as ExpressCards. Ventura is only at fairly early beta stage so you may want to consider this a bug... If you delete the icon by holding [Command] whilst dragging the icon out of the menu but it keeps coming back at subsequent reboot, I've no idea how to remove it permanently if there's no option in Systems Settings to that effect. Good luck.

yes here is my efi EFI840g1.zip
