+4 stars for bringing this to MacOS, -3 for stability issues somehow related to typing. It seems that as long as you type slowly enough, you'll be able to type in your entire password; but the faster you type, the more often you'll see "The application RDC has unexpectedly quit." If you don't need "high" encryption and don't apply the Q324380 (MS02-051) patch, I recommend XFree86 + OroborOSX + rdesktop (rdesktop.sourceforge.net).
