I have recently updated to macOs Catalina, and i wanted to reinstall technic launcher to play with my friends. I already have java installed, but when i open the .jar file, it pops up on my dock and disappears twice. When i check the logs there is usually one log for each time i open it, along with nothing in the surrounding folders. I have tried to 'reinstall' technic multiple times.
