No, not even close. There is more that doesn't work than works. Of what I use, all I got was python3 and git. But no python3.8, no ffmpeg, no erlang, no gnutls, and on and on.
I looked through brew.sh. Apologies if I'm missing something, but I don't think I am.
There's something really offensive about apple being too cheap to just pay some homebrew devs. And dumping the work of the arch swap onto charity effort.
I just linked you to the official page which shows what works and what doesn't work, and your response is that you're still right and everything works?
ffmpeg has so many configure options, I always avoid building it with brew.
