Yes, use the Mac flasher from (I assume this is an PPC Mac - if not, then install Linux or something on a spare partition): http://tablets-dev.nokia.com/d3.php And invoke the flasher with "flasher-2.0.macosx --disable-rd-mode". And once that is done, you will want to update. Instructions can be found here: http://wiki.maemo.org/Updating_the_tablet_firmware The syntax for the Mac flasher is the same as the Linux one.
