I used @Jazzoo's EFI from https://github.com/CloverLeafBG/Dell-Latitude-7490-OC-Hackintosh.
This got things working!!! The one thing I noted other than the difference in the number of SSDT's was that they were using was the fact they were using a MacBookPro15,2 SMBIOS and I had used a MacBookPro14,1 SMBIOS which came out of a suggestion from the Dortania guide.
