DVDFab HD Decrypyer for Mac, working as a DVD decrypter and Blu-ray decrypter, is a cost-free and simplified version of DVDFab DVD Copy and DVDFab Blu-ray Copy. It can copy nearly all the DVDs (except for adult DVDs and those containing multiple vts protections) and Blu-rays released before 2018 to blank discs or to the hard drive on your Mac, in "Full Disc" or "Main Movie" modes only. It's one of the always free portions of DVDFab, which can work off internet connection environment, and needs ImgBurn or Nero Burning ROM installed for DVD/Blu-ray copy or backup.
