Why do you have duplicate kexts /L/E and /S/L/E?
Kext with invalid signatured (-67062) allowed: <OSKext 0x7fc97ef39890 [0x7fff931d28e0]> { URL = "Shiki.kext/ -- file:///Library/Extensions/", ID = "as.vit9696.Shiki" }
Kext with invalid signatured (-67062) allowed: <OSKext 0x7fc97ec9b480 [0x7fff931d28e0]> { URL = "Shiki.kext/ -- file:///System/Library/Extensions/", ID = "as.vit9696.Shiki" }
Also, Shiki.kext, IntelGraphicsFixup.kext (and other related kexts) are deprecated... replaced with WhateverGreen.kext.
AppleBackightInjector.kext deprecated replaced with AppleBacklightFixup.kext.
Also, NullEthernetInjector.kext is not for your scenario (you have RMNE).
Your kexts are installed to the wrong location. Should be /L/E, not /S/L/E. Refer to the FAQ.
