Installing Videux is easy, and is just like installing most Mac apps. Download the app (either the trial or after purchase above). Double click on the downloaded dmg to mount it, and then drag Videux Pro DL from your that folder to your application folder. The build is code-signed and we are a known developer, so you shouldn't have to do more than just ok it to run the first time. Then just start it like any other Mac app. You'll be greeted by a short tutorial to help you get started.
System requirements: Mac running El Capitan, Sierra or later.
