For testing = I've been using the mini-memstick images from the -CURRENT snapshots, = most recently the one from 20140903. I am able to select "EFI Boot" on the USB device from the Mac's boot = menu, and it does _something_, but the screen never changes--the image = of the boot menu is displayed indefinitely. I think it is actually = booting since there is drive activity and the caps lock key indicator = starts working a few seconds in, but the screen just stays the same. = Thinking the resolution of the Retina display may have been an issue, I = tried booting with it disabled (lid closed) and an external monitor and = keyboard. The result was the same--Mac boot menu frozen on the external = display. Is there anything I should try to troubleshoot or debug this issue? = Anything else I should include in a PR? I can test patches if needed = (probably after building an image including the patch from a VM). Thanks, JN
