Can anybody explain to me how I can patch AppleRTC.kext or upload one ready to go?
just run the command (copy/paste texte) into terminal app
perhaps just repair permissions (with disk utility optional I think)
and recreate cache to be sure...
sudo chown -R 0:0 /System/Library/Extensions
sudo chmod -R 755 /System/Library/Extensions
sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions
