Feature request: macOS support

[sxyazi]

Hi, I am maintaining a terminal file manager called Yazi. Some users have asked me if it's possible to preview images in Alacritty on macOS.

This works well with X11/Wayland (sway, hyprland and wayfire), where ueberzugpp creates a sub-window to display images. However, it seems that macOS does not support this. So I'm wondering if it's possible to achieve the same in macOS.

I am willing to try contributing this feature, but I don't have any experience with C++/macOS and might need some guidance, like where to start.

Thank you for creating this awesome project, allowing terminals that don't support images to display!

there's a fork of alacritty that has sixel support, maybe it also works on macos. They could also use wezterm/kitty.

So I'm wondering if it's possible to achieve the same in macOS.

natively using metal (or Cocoa?) maybe, don't know, a deep dive on their documentation would be required. It could be an interesting experiment.

MacOS also has XQuartz so X11 could work, the terminal also has to run under XQuartz though.
