Audio Configuration
Now we have to take care about Audio.
Until now, each one of us had to patch AppleHDA.kext (if you have dsdt edits) or get HDAEnabler (without edited dsdt), and every system update we had to repatch it.
Now it's time to try a different method. Thanks to the Clover so called "Patch on the fly", and to the great support of Forum Moderator Toleda, here's a simple method to patch Audio that would (hopefully) survive to the System Updates (already tested from 10.10 to 10.10.1).
- Open Terminal and type
Code:
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1
- Open Applications/Utilities/Disk Utility, go to the menu bar find Debug and flag "Show Every Partition"
- Now in Disk Utility you'll see all the partitions, included EFI (greyed out, cause it's unmounted)
- Mount EFI partition from Disk Utility and close the window
- Download audio_CloverALC-master.zip from
toleda's repo, unzip it and leave it in Downloads folder.
- Open Downloads/audio_CloverALC-master and unzip audio_cloverALC-100.command.zip.
- Double click on audio_cloverALC-100-v1.0.2.command, a Terminal window will open, type your password (even if you don't see anything) and press enter
Code:
