@HeatherHask605, This really depends on what kind of course you're going to record: talking head, screencast demonstrations or PowerPoint presentations. I do all three. I use Camtasia 2018 running on Windows 10. I read good things about ScreenFlow on Mac. Others will undoubtedly throw out other free options. Camtasia is expensive ($299 unless on sale). You can however get a great deal done on a 30-day free trial of the product. Hope this helps, ---Brian
