I had Camtasia on my PC, and the closed captioning was wonderful. Then I upgraded to Mac. It's not there. I talked to support, and they confirmed it's not available on Mac. I am legally required to provide my students with closed captioning on every video I make (I teach computer science in college). This is an extreme legal liability for both my school and for me. While I don't have any deaf or hearing-impaired students that I know of, I have a number of student who have ADD who rely on CC to keep them focused. I won't be renewing my Camtasia license again until you add this feature for Mac. I can't believe your company is so callous about something so important!
