2- Get It

A macOS GUI for youtube-dl

A macOS video/audio downloader. Think of it as a youtube downloader that works on many sites.

Get It will download audio and/or movies from many websites such as YouTube, BBC, Instagram, ... It's a GUI round the popular YouTube-DL command-line program but with an easy to use interface. It will save your settings dynamically or you can restore the default settings. The default settings will download the audio from a video, convert it to an MP3 and save it to you downloads folder. This was, in my opinion, the mostly used setting.
