Mac no longer works in the CI

[royfalk]

It seems that MacOS 13 and newer are not supported by CMake.
With the deprecation of MacOS 12, I attempted to increase the version of the CI (#928 ) to 13 and the build broke.
It needs fixing both for CI and for people who want to play on Mac.

Looking at my PR (#891) I noticed that some of the dependencies that were assumed have changed. I'm going to build a bootstrap script for MacOS and try to detect stuff so install it.

good progress on the PR; but need to figure out how to set some of the libs with homebrew
OS 13 and 14 are almost to the same point in the build cycle

Seeing something odd with Boost Python in Homebrew. It's supposedly built against Python 3.12; but Homebrew installs Python 3.13. Following the simplest route yields errors between the two versions, but I figured out how to get it set correctly so it's building against Python 3.12 only to have it not work as if it's built against Python 3.13.

That looks like good progress. Let me know if you need some help.
