I just saw this article. I’m just passing this along in case you didn’t know like me. I recommend reading that article but the short and sweet version is that MacOS 10.15 (Catalina) has depreciations and 10.16 will not be shipped with scripting languages.

As they've quoted in the article, I'll share the important part from the MacOS 10.15 beta release notes:

Scripting language runtimes such as Python, Ruby, and Perl are included in macOS for compatibility with legacy software. Future versions of macOS won’t include scripting language runtimes by default, and might require you to install additional packages. If your software depends on scripting languages, it’s recommended that you bundle the runtime within the app. (49764202)

Use of Python 2.7 isn’t recommended as this version is included in macOS for compatibility with legacy software. Future versions of macOS won’t include Python 2.7. Instead, it’s recommended that you run python3 from within Terminal. (51097165)

I was a little shocked to see this but then also not shocked at the same time.

Any thoughts?
