Toleda,
Can I get some general advice? I set up my system back in September, with an i5-4670k and the Asus Z87I-Deluxe, running 10.8.5.
With your tools (and a little help) I managed to get the regular audio working (I output to my receiver via Digital Optical), as well as the wifi. However, I still haven't managed to get the Bluetooth working (it doesn't have the line through it, but it will never connect to anything) or HDMI audio. I kind of gave up after I got the regular audio and wifi working, since it worked "good enough".
Would it be easier to upgrade to Mavericks to get the BT and HDMI audio working, or should I stick with Mountain Lion?
