How to update Mercurial on the Mac to use CAC Authentication

Anyone have an idea as to how to update Mecurial on the Mac to use CAC Authentication?

I have a supplied version on my work PC but would like to use the Mac for all my work.

Solution

You can install additional packages or newer versions on MacOS using third party packages from e.g. macports or homebrew. I prefer macports. Both provide a good documentation on how to start

EDIT: Have you checked this page?

Second Edit: Might be mercurial needs python 2.7

So no need in this case for macports or homebrew
