Does FEditor work with mac?

I’ve tried opening it but it keeps telling me to check the console and there’s nothing there.
I really just need to check if the portraits I’ve made work.
Edit; just realized I may have asked something similar earlier. My b if so
Double edit; alright so it does work on mac but Java doesn’t wanna play ball and run it. Any ideas?
Triple edit; its the same issue with Nightmare 2.0
moar edits; the launcher is Jar Launcher 14.9.0
