QTR-Quadtone RIP

After the latest OS X update 10.8.4 QTR in calibration mode prints separation file in calibration mode strangely: K, C print but with odd densities, M stops printing at 50, LC at 5, Y at 20 and LM not at all.

Deleted printer, QTR in lib/, and app/ and restarted. Reinstalled QTR and printer and the problem persists.

Any advice?

For now I am assuming that files like the one below (from Paul Roark) let me print an untagged grayscale file as if I was using calibration mode. Am I right?
