Nix used to use headers from macOS 10.10 or thereabouts, even on newer
versions of macOS. I don’t know if this is still the case. The problem
is that our compile‐time feature detection code detects the wrong
features as a result.

Could you perhaps try changing src/nsterm.h so that this:

#define NS_DRAW_TO_BUFFER 1

is always defined? You should be able to just delete or comment out
the #if and #endif.

I don’t know how easy that is for you with Nix, hopefully it’s pretty
straight forward.
