I wanted to download a Facebook video. After about an hour of google searching through all the phony apps that say they can download FB and can’t — I found this screen recording app and it works sweetly. I recorded at 30fps and it got the job done on the first try with NO hassles. My computer is an old macbook pro with Mavericks and this software worked great. A breath of fresh air in a room full of farty amateur software that doesn’t do jack.
