Hi, and welcome!
Please see the FAQ: What's a reproducible example (`reprex`) and how do I do one? Using a reprex, complete with representative data will attract quicker and more answers. This question doesn't require one, however. (Still, screenshots usually don't help all that much if they are any smaller than this one.)
I have your setup and just had a successful install. XQuartz and clang/gfortran aren't relevant, since this package didn't require compilation.
I've not seen the SSL error before. Can you connect to https in the browser?
Without an SSL connection, getting the "not available" message is expected.
