<< Solved >> Audio not working after 10.14.4 update.

[OPAEU]

Hi, I'm in need of help to fix audio in my Dell Inspiron 14r 5421. I'm using AppleALC.kext and layout-id=29 boot flag, and the audio was working perfectly fine until I upgraded to version 10.14.4 yesterday, and audio stopped working (I also updated Lilu.kext WhateverGreen.kext, AppleALC.kext and Clover to the latest versions). Any help will be apreciated.

from your kextcache output file:

Kext rejected due to improper filesystem permissions: <OSKext 0x7fc4c2715f70 [0x7fff99e5a8f0]> { URL = "AppleALC.kext/ -- file:///Library/Extensions/", ID = "as.vit9696.AppleALC" }

delete it and reinstall it
