I trying to install maverick with a unibeast 5 prepared usb. I get stuck during the first boot.
All is wel, chimera comes up, select usb Disk, apple logo appears, spinning wheel. But when it seems finished the display shuts off. No Signal.
I tried: Graphicsenabler=Yes an No...
Are you still intersted i a solution?
The ahci entry is somewhere hidden in the BIOS. I have to look again but i have been in the same loop. And if sata is not acha then osx can't see no drive, therefore this no entry symbol.
