unimatrix725 Posted June 3, 2013 Share Posted June 3, 2013 Great Post! I will have to give this a try when I have some spare time. I hated fixing my dsdt, this would have saved me some time. I currently use VoodooHDA it was the easiest and works great! https://github.com/AppleLife/VoodooHDA Link to comment Share on other sites More sharing options...
