don't know much about MacOs.  I'd try look at this info page

(info "(elisp) Multiple Terminals")

(x-display-list) will give you a list of the displays available for
the Xserver.

If you want the sizes of the displays I don't know how to get them
directly from elisp.  You can use the system command xwininfo for the
root window.

xwininfo  -display 0:0 -root

display is in the form HOST:SERVER.SCREEN.  You will need to parse the
output of the command and extract Width and Height.

  Width: 1280
  Height: 1024
