 And for Mac? 

 JDownloader 😬 

 Invidious could be another option🤞🏼 

 youtube-dl command-line tool. some nerdery required 

 'member when GitHub took down their source code? 

 I use this.

 That is foreign to me 🙃 

 If you run a Bitcoin node you can figure this out! Download the Mac installer from the releases page. You'll need to open up terminal to run the command. 

 seconding yt-dlp. very easy to run from cli. 

 Tubular on  f-droid 

 On Android . . . GrayJay, NewPipe, or BraveNewPipe all work.

GrsyJay is nice because it let's you search a bunch of streaming platforms at once.

Futo GrayJay has an F-Droid repo. 

 And on Mac? 

 yt-dlp run from the terminal. need to have ffmpeg as well. use homebrew for both.

 Do you need help installing Linux? 

 Maybe the "Video DownloadHelper" Firefox add-on will work on Macs.
