Following the advice given above by Digital Guru I upgraded the Blu-ray recorder Tsstcorp BDDVDW SE-506AB Ver. TS01 using TSSTcorp's website instructions. No change, same errors using fresh BD discs. I have never been able to burn a BD disc with this recorder, but plays BDs fine.
Perhaps I need to invest in a new Blu-ray burner for the Mac. Any further suggestions to fix this problem, or recommendations on a good Blu-ray burner?
