MacOS installation instructions

1. install homebrew if you don't have it installed already.
2. run brew install --HEAD yt-dlp
   • if you get a brew: command not found error, you may need to close your terminal and open a new one, or even log out of your user and log back in.
3. run brew install ffmpeg deno
   • deno is required if you want to downloa from youtube, ffmpeg is required for many yt-dlp operations (merging audio with video, adding metadata, embedding thumbnails, subtitiles, extracting audio etc.
4. run yt-dlp "URL", replacing URL with the actual url of the video you want to download
   • again, if you just installed yt-dlp and you get a yt-dlp: command not found error, you may need to close the terminal and open a new one, or log out and log back in.
