I have an issue with booting this system while monitor(s) (one or two) and plugged into the mini-Display ports. It will never boot. If I unplug them and plug in a monitor connected via DVI, it boots fine.
So, I have been keeping a spare monitor around for when I need to reboot. Unplug the two monitors, plug in the DVI-connected monitor, let it fully boot up, and then unplug that monitor and plug in the two monitors I actually use (which, then, work fine).
What is the deal???
