Do you even do your homework? Ratzlaff didn’t design OS X! He was just a people manager. OS X was designed Bas Ording, Imran Chaudhri and Don Lindsey. Since then both Ording and Chaudhri have gone on to design the iPhone and more for Apple. Lindsey left after the first version and has gone on to Microsoft. Ratzlaff just took the credit for all their work to ensure a job after Apple. Check the patents!! Think hard how someone who says he designed OS X could have designed something awful as “Kapitall”
