I'm in the exact same position! I'm attempting to multi-box my machine (H97N-WIFI, i3-4360, NVIDIA GTX-750Ti, 16Gb Crucial, 2x256Gb Samsung 850 PRO SSDs) - one SSD for OSX 10.10, and the other for Win8.1:
- Downloaded 10.10 from the App Store.
- Built the UniBeast using a USB stick
- Tailored the settings for my BIOS as per the UniBeast installation guide
- However, the loading of the boot screen to OSX through UniBeast hangs indefinitely right at a specific line (through verbose loading) involving the Bluetooth Controller Transport.
I tried all of the variations I could find (-v, -x, -s, etc...) through this site and others, and every time it fails at the exact same line.
All I need to do is get the OSX boot loader to mount successfully - I haven't even been able to install anything to the SSD yet!
Any ideas here?
