Looks like I have one more hurdle after my recent motherboard swap. The problem is that, when booting into Mavericks, it hangs / freezes at the Apple Logo about half the time.
I can tell that it's going to happen because the screen stays on full brightness, opposed to going to the most recent dim-ness that I like to keep it at.
The apple logo and grey screen come up as normal, the little progress circle thing spins for 1 minute, and then it just stops spinning and I do a hard-reset. Strange that it just happens sometimes, like as if it flips a coin to decide.
Since swapping Mobo, I have updated drivers and Bios on Windows, reconfigured Bios settings, and updated Clover.
