Hello, I've installed Mac OS X Yosemite 10.10.1 on my Alienware X51. In the beginning i had many problems like Reboot Loop but i solved it with the Haswell Kernel and the npci=0x2000 Flag. Then i installed it. And the next problem was the Missing Bluetooth Controller Transport Error when i booted into OSX Yosemite. I fixed it by removing the Kext from the IntelHD Driver. And the next problem was that it was stuck at the [IOBluetoothHCIController][start] -- completed screen. Then i fixed it but after i configured my Hackintosh a Kernel Panic appeared. See in the attached Photo. And sorry for my Bad English. I'm from Germany. Hope you can Help me!
