You could:

        go to the code tab at https://sourceforge.net/p/s7commwireshark/code/HEAD/tree/;

        clone the repository;

        download the Wireshark 3.4.7 source, so the Wireshark header files are available, if you haven't done so already;

        run the tools/macos-setup.sh script in the Wireshark source tree, so the header files for the support libraries are available, if you haven't done so already;

        make sure you have Xcode installed;

        build it;

        install it in the appropriate directory;

but we don't have a tutorial on doing that, so you'd have to figure it out yourself or keep asking questions.

Another semi-automated way, without setting up a local build system is:

- fork the github wireshark repo (github.com/wireshark/wireshark)

- clone locally, create a new branch, manually incorporate the dissector, push the new branch

- the github workflow for macos compiles the branch including the dissector and creates binary distribution for it.

IT *should* give you a working mac bin package, despite I've never tested it. However if it works, it gives you a dmg without the hassle of a local build env.
