I tried installing VoodooHDA.kext-Snow32/64-v0243 with cVad correction but it didnt work, how do I properly install it?
Move the kext into your /System/Library/Extensions/ directory , it'll ask to be authenticated, click authenticate, type your password.
then open a terminal and type the following three series of commands, in order:
CODE
sudo chmod -R 755 /System/Library/Extensions
sudo chown -R 0:0 /System/Library/Extensions
sudo kextcache -v 1 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions/
that'll install the kext properly.
