Make sure you installed both AppleALC.kext and Lilu.kext and delete any realtekALC.kext and/or VoodooHDA.kext you may have installed in your system. Rebuild kernel cache using Kext Wizard or any kext management tool then reboot.


As for the Mac App Store, check that your Ethernet connection is set as en0 (you can see this in System Profiler) :




If not, delete all network interface in System Preferences > Network and also, delete this file : Library/Preferences/SystemConfiguration/NetworkInterfaces.plist


Again, reboot then add your Eternet interface first.


THANK YOU again!!!


Everything works perfectly now :thumbsup_anim:
