A small update: I tried with an external keyboard and mouse attached and it booted up to the user interface.

But unfortunately neither the keyboard (MS natural 4000) nor mouse (mac mighty mouse) allowed me to interact with the os. The cursor was stuck in the middle and even ctrl-alt-del did not work.

Never the less it is a start.
Afterwards I tried to have only one device attached at a time and it still booted up the same, even when I detached both

. So my previous post was misleading, the current state is: ReactOS boots on MacBook 3.1, but I can not interact with the OS because no input is accepted.

Well, it seems that now I get up to the user interface, but can not interact with it. Is it also what you get too?
I can not try the truck because I don't know how to build a live cd out of it, but with the next release sheduled this month, I think I can wait until then.
