Further research is now completed. This is the easiest method for Apple driver compatibility.
Use Brigadier: https://github.com/timsutton/brigadier/releases (https://github.com/timsutton/brigadier/releases) - To download all Apple drivers for Win10PE
CMD Line Usage(to manually download drivers):
brigadier.exe --model=MacBookAir7,2
brigadier.exe --model=MacBookPro15,1
brigadier.exe --model=MacBookPro14,1
brigadier.exe --model=MacBookPro13,1
brigadier.exe --model=iMac18,3
brigadier.exe --model=iMac17,1
brigadier.exe --model=iMacPro1,1
By running all of the above commands you will get a downloaded copy of every modern Win10PE driver for all major Apple products. Only the above listed models need to be selected as some of the drivers cover more than a single model. (For example, MacBookAir7,2 covers almost every apple product from 2010-2015)
Place the drivers you would like to integrate into the Driver Integration plugin.
Enjoy! :thumbsup:
