I use xterm-mouse under Terminal.app just fine as I rely only on Emacs
pasteboard integration via xclip. (I use clipetty when terminals support
osc52--there's no easy programmatic test for that which I'm aware of so I
set that up "by hand.") I don't think it is a good idea to blanket disable
xterm-mouse for macOS users.

FWIW, one can detect it via getenv "TERM_PROGRAM" when set to "Apple_Terminal".
I'd suggest this is an exercise for the user. In my configuration, I have
various things I configure based on if macOS and the terminal program; one
being Apple's Terminal.app, another being WezTerm, etc.
