Thanks, yes, that is an option I’ve considered. My applet already checks for required components and handles the download and install for the user (who only needs to provide admin credentials). But, Apple’s recommendation is for developers to include a Python runtime with the app <https://developer.apple.com/documentation/macos-release-notes/macos-catalin…> I guess that's because apps can be finicky over which version of Python they require with as well as the range of modules required. So, I’ve been working with the developer of the Python tool my applet uses to use PyInstaller to build a single file executable containing the script, Python and required modules. That can be built by a GitHub YAML script and published for all Mac users. It’ll probably be built to run on macOS 10.15 Catalina and Universal2 architecture. My AS applet will then be able to download, install and use the executable in the same way as its existing components. Cheers.

How to include or install a Python runtime in an AppleScript applet
by Vincentius Vincentius Oct. 3, 2021

Oct. 3, 2021

Hello, I am not a Python developer. So, please forgive the intrusion. I have developed an AppleScript applet which provides a GUI “frontend” for a Python script provided by another developer. The applet runs on any version of macOS from OSX 10.10 up. The Python script is very functional but only works from Terminal and invoking it correctly it is complex especially for users not familiar with Terminal. My applet simplifies all that so Mac users can more easily access the functionality of the Python script. As you will guess, the applet currently works because Apple for many years have included Python2.7 in macOS. But, recently, development of the Python script has ceased and I have to move to another Python script (forked from the original) which is actively developed. My problem is that the new Python script requires Python3 which is not in macOS. So, I need to find a way of providing a Python runtime to users of my applet. Can anyone help me with advice on how to create and distribute a Python runtime (with my applet) ? The shebang in the script has this: #! usr/bin/env Python3. I guess that means the script will call the Python3 stub located in /usr/bin/. But, that will invoke the Xcode Command Line tools download which most of my users will not want. How do I redirect that call to a Python3 runtime ? As the wider Mac developer and user community learn that they need Python3, there will be a growing need for simple Python3 runtimes. But, the macOS distribution currently available includes the IDE and other development tools which, again, most of my users will not want. Would it possible to prepare a runtime installer suitable for users who wish to run Python apps and scripts ? Thanks. Garry macytdl(a)gmail.com

Kevin, many thanks. Requiring users to install Python themselves might be asking too much for many – they would just look somewhere else for a tool that doesn’t impose requirements. Anyway the standard install comes with developer tools that the ordinary user will not need and, from my experience, object to. I’ve been pointed to PyInstaller which might be a solution for distributing the Python script separately. Cheers.
