Sup brahs, I got a late 2009 uni-body Macbook (non Pro) and after a 3 hour set I close the lid and turned off the Kontrol S4 like always and all the sudden I had no WiFi and the Mac speakers were disabled (crossed circle). After some tests it found a lot of wrong permissions in the airport that it seemed to fix but still no Airport installed. I heard it could be a bad or not properly connected airport card but I didnt move the thing and when spinning it sits on cushions so it minimize vibrations. The sound was fixed by putting is headphones, closing the lid, pulling the headphones out and opening the mac again...

It;s odd this mac has so many issues... any ideas?
