prim_tty:init(#{}). does not work on macOS #10174
Description
Describe the bug
Gazler/termite#4
prim_tty does not work on macOS
macOS: Version 15.6.1 (24G90)
Processor: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
Terminals: Alacritty and Terminal.app
shells: fish and bash
I checked the same code on Linux and it works.
To Reproduce
run iex and :prim_tty.init(%{})
or run erl and prim_tty:init(#{}).
Expected behavior
Should return tty state
Affected versions
erlang 28.0.2
elixir 1.18.4-otp-28
Additional context
