So after upgrading to a mbp as my main machine, I retired my old imac to the bedroom for media center duty. I've got things close to how I want them with front row and plex doing most of the dirty work. For my planned use, no keyboard or mouse are needed. A combo of the apple remote and snatch on my itouch are doing quite well. The problem is, if I turn the machine off, it sees no mouse or keyboard over usb, and attempts to find them over bluetooth. Does anyone know how I can get rid of this? I've tried just turning bluetooth off before shutdown, but this doesn't seem to solve it. This is REALLY annoying, as I'd prefer to keep the machine off more often rather than having is sleep all the time.
