Hi! i recently bought hardware for my new hackintosh high sierra 10.13.6 (aorus gaming 7, i7 8700k, gtx 1080, corsair 32gb @4000 and m2 970 evo) i found an efi file (10.13.2) from a guy that knows a lot of hackintosh and have same specs like my mine, except the gpu (amd) and sdd, i tried it, the ram shows up at correct speed, everything looks perfect except the gpu, its like im in safe mode, i know is the driver and the setup in the efi file,
  • How can i change it to nvidia web driver and remove amd gpu?
  • do i have to change something else because the file says 10.13.2 and i´m 10.13.6?
  • Do i have to change the smbios so i can have imessage ?
  • Is there a way that airdrop works? (i have in both hacks Tp-link ac 1900 didnt needed drivers)
  • i tried to update kext files like lilu 125 but now i have to use -liluoff to get it booting

Sorry for my noob questions but i want to make the most of this hardware instead of just running osx in "ok, its working mode"
