About This File
Yosemite brings new AppleHDA which one cant be correctly patched by Simple AppleHDA Patcher (bin-patch).
Solution for masochist who still using patched AppleHDA... install this kext and add Kext-Dev flag to boot arg.
1. Open Terminal
2. Paste this into Terminal window "open /Library/Preferences/SystemConfiguration/com.apple.Boot.plist"
3. Add flag in correct place (look at screenshot) flag "kext-dev-mode=1"
4. Save changes.
DSDT/Clover Layout injection still needed.
