[QUOTE="extremelychewy, post: 1098220, member: 59936"] I have a couple more pieces of information I wanted to throw out there. After attempting the install, where it reboots mid-install, but never resumes installing, a locked boot.efi file appears on the USB drive. If I'm understanding the boot process of the mac properly, shouldn't this be the file that allows the drive to be recognized as bootable? I believe EFI is the equivalent of a pc bios? Anyway, another thing that I am noticing is that the small green "activity" led on the USB drive (the one that lights up every time it is accessed) does not light up during the booting process or the optional boot screen. Is it possible that the computer just isn't even powering the USB ports during bootup so it isn't recognizing the drive is even there? [/QUOTE]
