hello, i am new here. I just installed onyx on my mac. I have already the mavericks system. After i launched onyx it showed me the message i need to restart my mac with pressing "R" for repiar and repair some stuff ( i don't know anymore what it was). So i did it, i restarted and with pressing shift + r and a loading bar showed under the apple logo while launching. The problem is - this bar comes to like one tenth and then my mac automaticly turns off. This is really werid because now i can't even turn my osx on. I would like to ask anyone who have a clue on this issue for help. I will be very grateful for any advice. thanks
