Does your post processing script have an executable bit enabled?

Does your post processing script have an executable bit enabled?

I previously had a path set to open the Python Launcher .app. Since it's a Mac, it seems to handle the executables differently from Windows, i.e. the standard .exe. Ultimately, the .app path was a dead end since the Python Launcher is basically just an options menu but then the pathing for Mac is also less straight forward in general, so it could be a screw up in how I wrote the command to activate the script.

For Mac it works similar to the Linux one, rather than Windows.

OrcaSlicer runs post processing scripts using default shell interpreter. Shel interpreter reads first line of the script (shebang line) and tries to run interpreter for that script.

Your error may be either:

1. Executable bit missing for the script
2. Interpreter specified in shebang line either not found or cannot be executed, for example due to permissions reason.

You may find hints which might help you troubleshoot issue: https://discussions.apple.com/thread/254067051

Yeah. I have previously chmod'd all folders in the path, gave OrcaSlicer admin permission and some other things. None of those worked. That link you posted is an excellent explanation. I'll give it a shot and report back with my findings. Thank you, @buzzhuzz!
