Okay, I recreated my USB and made sure to follow the guide closely.
I am using a 8GB USB 2.0 flash drive.
I made a 500MB DOS partition named CLOVER EFI and a HFS+J partition named install_osx.
I have FakeSMC, GenericUSBXHCI, and VoodooPS2Controller kexts in EFI/CLOVER/kexts/other.
I have HD4000 1366x768 graphics and am using that config file renamed config.plist in /EFI/Clover.
I then built the OSX installer using the Unibeast method, selecting install_osx as the destination, Yosemite as the OS, and the Laptop Support option.
The installer still crashes at Bluetooth controller transport, both booting normally and in safe mode.
I'm sure I missed something very simple, however I reread the guide and I can't seem to figure out what it is. I'd really appreciate if you could point me in the right direction as I'm at a loss for what to try next. Thanks!
