Uses under 1.5 MB of memory at any one time (most of it is used for drawing the window).

Unfortunately there is no screenshot and I have no access to a Mac at the moment, but if View.c is where things actually happen, that is a huge amount of memory just for a (resizeable?) window with a little filled rectangle in it. The memory usage of a trivial app like this should be measured in kilobytes.

Comparing applications written in the same language across platforms is IMHO a good gauge of their relative efficiency. From what I've seen, Win32 and Linux (Xlib) are pretty close but Mac is clearly very "think different". I'm sure the liberal use of string constants here doesn't help either.

Here's a related interesting comparison: https://zserge.com/posts/fenster/

It also depends on how the operating system and frameworks actually work. For instance, the backing store for the window may be “charged to” the application on macOS but may be provided by the OS on another platform, or there may not even be one.
