Hi people, This is a preliminary installer to activate the sound card IDT 92HD87B2/4 (111D:76D9) in MacOS. This new version of the installer does not contain AppleHDA patched Kext. To work properly, it must be installed over vanilla AppleHDA Kext. I want to thank the whole community for their efforts and content provided, because without these it would not be possible to create this installer. I would appreciate comments and suggestions!!
