I have been trying to install Mac OS sierra onto my Latitude e7470 using the bootpack provided. I have updated my bios to 1.15.4 and have changed the necessary settings in the bios (sata AHCI) as well as my DVMT to 0x3. I am able to boot the installer however i notice my HDD activity light stays solid the whole time during boot. When I go to disk utility to format the SSD it will stay on unmounting disk for a good 10 minutes and format for another 10. When i go to install it will fail because "Target volume appears to be invalid."  My ssd is an sata III Intel ssdsckgf256a5, Latitude e7470 i7-6600u with qHD touch. I have uploaded my efi folder and Pictures of the issue.

Your system has a touchscreen, so my files might not work properly for you. Go ahead and export the raw files, I'll try to patch them for you.

Boot to Clover, hit F4, this will export to the USB drive. Compress and attach /EFI/Clover/ACPI/Origin folder here

 

Are there other differences besides that? Does it have an Nvidia card too?

Good news and bad news, you were able to fix the PCI device problems, I now have wifi showing up now and so does the NVME SSD. However the intel m.2 sata drive I was originally using still seems to stall out  un-mounting and formatting. I know this drive is good because it was running Windows 10 without an issue. I will proceed using an NVME SSD. 

Thanks for your help.

Replace your /E/C/A/Patch files with this

I have updated my boot pack with the Mojave version in preparation to install Mojave. When I re-add these patched files (deleting the old ones in ACPI/Patched) the System wont boot due to ACPI errors. I can use the stock (boot pack) ACPI/Patched files but I have lost touch screen functionality again. can you Modify the ACPI/Patched files to allow Touch to work again?

Thank you.
