I dig the fact that Camtasia for Mac tried to do a "ground up" re-write to make it more of a native Mac app, but it seems like boatloads of stuff vs. the PC version dropped. Plus, if it's totally different than the PC version (in every way) the learning curve is steep for vets.
Hey everyone- with the latest releast (v3) of Camtasia for Mac, we've added some significant features that have been on the Windows side (and vice versa). We've also made the two programs look and behave much more similarly. Camtasia for Mac now includes grouping and quizzing, two of the biggest and most asked for features. While not everything is supported on both, you can share projects between platforms and we think most of what you care to share is cross-platform compatible! https://www.techsmith.com/camtasia.html
