I support the USB 2.0 vs 3.0 on a Gigabyte x58 UD7A board, could not get to the installer screen on a USB3 port.
It also requires that I used the "GraphicsEnabler=no", and I add to that line "-x" safe mode seems to get to the installer more reliably. I do use a NVIDIA EVGA GTX 670 card.
=======================================
However, I cant seem to get the Mac installer to see my SSD drive, when it asks were to install OSX my choices are blank, no hard drives listed.
I have tried the default intel ICH10 SATA slot zero and one, tried the SATA Marvell 9128 chip slot and the JMicron362 slots, I tried a few different cables.
I tried two SSD's in all of the slots above, the first is a brand new blank Samsung 256GB SSD, unformated,and the MOB sees it during start up. I also tried a Crucial C300 older 60GB drive, it is seen in the MOB bios start up and Camelion sees it as well since it has a windos installation on it, and camelion gives the option to boot windows (I dont use it obviously, I boot from the Unibeast USB)
No other cards installed. Video is in first PcIE slot.
I made sure the MOB BIOS is set to AHCI in all cases.
Any ideas?
