Hello

After some day to read all tutorials and settings from other users who succeed to install this os x I still have some major problems.

1. No audio hardware detected - no sound
2. If I try to copy something from drive to another computer freeze and I need a resest
3. some drives ca not be visible in finder

I and bios update, video drivers update, reinstall os x several times.

What really should I must do?

My config is:

Gigabyte GA Z97X UD5H
i7 4790K
32 GB Crucial DDR 3
SSD 128 GB Samsung 830 EVO & 500 GB 850 EVO & some Sata 2 and 3 drives.
Gigabyte GeForce GTX 760 4GB DDR5 256 bit

HELP please.

I have the same MOBO and same problems -- copy = freeze, no audio. Did you ever find a solution?

Disable hard drive sleeping in your preferences>energy saver tab, and also test by using a usb audio device if its 100% a problem with the OS
