That all looks pretty much like I'd expect.

Can you check if it ever reaches the end of ns_select? You could
either stick a breakpoint at, say, like 4733 of nsterm.m, or make it
print to the console or whatever.

I suspect that since you're seeing a spinning wheel it's not reaching
the end, but we may as well find out for sure.

You're running macOS 10.15, yes?

Do you use Homebrew or something else?

Does 'emacs -q' also freeze up?
