Hi , first of all , Thanks Jake Lo . My E7440 is running Mavericks right now !! I only have a little problem..when i plug any headphones don't work.. it is detected in system preferences audio , and silence the internal speakers...but don't sound. Edit: also i made mi own SSDT ( i have a i5 4200u) , but i see it only up to 2.4 ghz .. is this normal ?
