On the iMac 17" with the Superdrive - DVR-105 (Pioneer) Toast 6 now burns bin/cue files perfectly.

I had an error with Firestarter and MMB reporting "cannot accept cue sheet variant" and could not figure it out. It seems to be a problem with cdrdao and the drive (more on Pioneers part)

Unfortunately, I have not found a fix yet (tried different versions of cdrdao and everything) except using Toast 6.
