For TuxGuitar, you need to install first the Java DevelopmentKit (it is an extended version of Java if I understood correctly) and then install TuxGuitar and it should run perfectly.
Here is the link Java Development Kit
I've installed JDK 8 but still no dice. The program appears to open, but then closes again immediately. Several other people on the user reviews / download page are reporting the same issue of the program not opening on mac: https://tuxguitar.en.softonic.com/mac/comments
If you run it on Mac with no problems, it might be that you are still back on a very old version of macOS? I'm on High Sierra here.

Did you re install TuxGuitar after installing JDK? I am not sure but it might change. I just know that this trick worked for me and other people on the french forum without doing any crazy code changes
Solved: it was old version of tux guitar causing issue. The one on first google result is bad: https://tuxguitar.en.softonic.com/mac
^ This is v1.2 and doesn't work on recent macOS.

The third google result is a sourceforge link to a v1.4, and that one does work:
